🍄 Fungi and Animalia Kingdoms: Diversity and Ecological Roles

This paragraph discusses the Fungi kingdom, which includes mushrooms, molds, yeasts, and lichens. Fungi are characterized as eukaryotic heterotrophs with chitin cell walls, lacking chlorophyll and reproducing via spores. Their role in breaking down decaying matter and forming symbiotic relationships with plants is emphasized. The four main types of fungi—zygomycetes, ascomycetes, basidiomycetes, and deuteromycetes—are briefly introduced, along with examples of each. The Animalia kingdom concludes the video script, describing animals as multicellular, eukaryotic heterotrophs capable of movement. The paragraph differentiates between vertebrates (with backbones) and invertebrates (without backbones), providing examples of each and noting the wide range of adaptations that allow animals to survive on every continent.

Keywords

💡Monera

Monera refers to a kingdom of single-celled prokaryotic organisms that lack a nucleus and membrane-bound organelles. In the video, it is mentioned that this kingdom is now divided into two: Bacteria and Archaea. Monera organisms are found almost everywhere on Earth, playing a vital role in processes like the nitrogen cycle and food production, such as making sauerkraut.

💡Bacteria

Bacteria are a group of prokaryotic organisms that are part of the Monera kingdom. They are known for their ubiquity and ability to obtain energy through various methods, including photosynthesis, chemosynthesis, and the breakdown of organic material. The script highlights that bacteria can be classified by shape, such as coccus, spirillum, and bacillus, and reproduce asexually through binary fission or sexually through conjugation.

💡Archaea

Archaea are another group of prokaryotic organisms, distinct from bacteria, that are adapted to extreme environments such as hot springs, the stomach of a cow, or the Dead Sea. They have a different type of cell wall and are antibiotic-resistant, as mentioned in the script. Archaea are crucial for understanding the diversity of life forms on Earth.

💡Plantae

Plantae is a kingdom of multicellular eukaryotic organisms that obtain their energy from the Sun through photosynthesis. The video script describes how plants have a cell wall made of cellulose, a large central vacuole, and chloroplasts containing chlorophyll. Plants are categorized into vascular, like trees and flowers, and nonvascular, like moss, with the former having tissues for transporting water and nutrients.

💡Photosynthesis

Photosynthesis is the process by which plants, and some other organisms, convert carbon dioxide and water into glucose and oxygen using sunlight. It is fundamental to the energy cycle on Earth and is mentioned in the script as the method by which plants produce their own food and release oxygen into the atmosphere.

💡Protista

Protista is a diverse kingdom often referred to as the 'junk drawer' of the biological classification due to its mixed membership of eukaryotic organisms that do not fit neatly into other kingdoms. The script notes that protists can be unicellular or multicellular, heterotrophic or autotrophic, and include groups like algae, amoebas, and slime molds.

💡Fungi

Fungi is a kingdom characterized by organisms such as mushrooms, molds, yeasts, and lichens. They are eukaryotic heterotrophs that obtain nutrients by breaking down decaying matter or forming symbiotic relationships with other organisms. The script explains that fungi reproduce through spores and have cell walls made of chitin, unlike plants.

💡Animalia

Animalia is the kingdom that includes all animals, from pets like dogs and cats to wild creatures like fish and humans. The script points out that all animals are multicellular eukaryotes, are incapable of photosynthesis, and are heterotrophic, meaning they must consume other organisms for energy. Animals are also characterized by their ability to move, with some exceptions like certain sponges.

💡Vertebrates

Vertebrates are a subcategory of animals that possess a backbone or spinal column. The video script mentions various examples, including fish, amphibians, reptiles, birds, and mammals. Vertebrates represent a significant portion of the Animalia kingdom and are found across diverse habitats on Earth.

💡Invertebrates

Invertebrates are animals without a backbone, making up the majority of the Animalia kingdom. The script lists several types, including sponges, cnidarians (like jellyfish), various worms, mollusks, arthropods (like insects), echinoderms (like starfish), and more. Invertebrates display a wide range of forms and adaptations.

💡Eukaryotic

Eukaryotic refers to cells that contain a nucleus and other membrane-bound organelles. The script explains that most life forms on Earth, including all plants, fungi, animals, and some protists, are eukaryotic. This cellular organization allows for more complex functions and structures within the cells of these organisms.

welcome to moomoomath and science in

this video I'd like to look at the six

kingdoms that are used to classify life

on earth the six kingdoms include

bacteria archaea bacteria plant Protista

fungi and Animalia these six include all

living organisms on Earth

for many years there are only five

kingdoms kingdom monera

is now divided into two kingdoms

bacteria and archaea bacteria let's take

a look at these six kingdoms and their

characteristics the kingdom monera

consists entirely of single-cell

organisms member this kingdom are found

almost everywhere on earth they are

found in hot springs kal stomachs and

almost every surface on earth all

members of this kingdom do not have a

nucleus or membrane-bound organelles

therefore they are classified as

prokaryotes they do have a cell wall

genetic material cytoplasm and ribosomes

bacteria get their energy in many

different methods

some get energy from the Sun other get

energy from chemicals like co2 while

others break down organic material this

kingdom is divided into two groups

archaea bacteria and bacteria archaea

bacteria is found in extreme

environments for instance some live in

the stomach of a cow or hot springs the

dead sea or even swamps and marshes they

have a different type of cell wall than

bacteria and they are antibiotic

resistant bacteria is also found almost

everywhere bacteria is very important to

life on Earth

although some cause disease most are

very helpful to us they break down food

in our stomach help the nitrogen cycle

and even help make some of our food like

sauerkraut we cannot survive without

bacteria bacteria can be classified by

their shape for instance coccus as a

sphere shape spur Ilham as a spiral

shape and bacillus as a rod shape most

members of the Monera kingdom reproduce

asexually in a process called binary

fission but some reproduce sexually in a

process called conjugation

it is made up of multicellular

eukaryotic organisms they give their

energy from the Sun they are producers

and they make up the bottom part of

energy pyramids let's discuss a couple

of traits that all plants have in common

first since they are eukaryotic they

have a new nucleus

the sales of plants have a cell wall

made of cellulose this cell wall

provides protection and gives the plant

cell shape plant cells also have a large

central vacuole where it stores water

and other materials plants have

chloroplasts that contain chlorophyll

and this is used to produce glucose

which we also call sugar plants take

carbon dioxide plus water with Sun light

to create glucose and oxygen in a

process called photosynthesis there's a

very wide range of plants they're

roughly 500,000 species of plants on

earth two major categories are vascular

and nonvascular plants vascular plants

at vascular tissue which allows them to

grow larger in size there are two types

of vascular tissue xylem which

transports water throughout the plant

and phloem which transports sugar

throughout the plant think of it backs

vascular tissue as our veins and

arteries and this allows some vascular

plants to grow very large nonvascular

plants move water and sugar around by

osmosis this limits the size of

nonvascular plants a common example

would be moss

you can also classify plus-5 plants as

plants with flowers and plants that do

not have flowers angiosperms are plants

that have flowers they contain a car

pool that has a stigma style and ovary

which is used in reproduction

most of our vegetables and fruits we

like to eat are angiosperms gymnosperms

do not have flowers and they rely on

airborne pollen to reproduce many of our

trees like pine and fir trees are

gymnosperms there's a quick look at the

kingdom plant system the kingdom

Protista is one of the five major

kingdoms this kingdom is kind of the

junk drawer kingdom because many of the

organisms in this kingdom just don't fit

anywhere else

most are aquatic but not all of them

some are unicellular but many are also

multicellular they are all eukaryotic

but some can reproduce sexually and

other a sexually some are heterotrophs

but others are autotrophs

some are decomposers and others are

parasites there are several major groups

of protists first some are classified as

animal like these heterotrophs can be

parasites predators and some are

classified by how they move sardines

move by using a pseudo pipe the common

example is an amoeba a mass geo porins

move by using a Jill Forge elem Giardia

is an example of this ciliates

move with hair like structures take a

look at this video of the amoeba and a

pair of Museum which is a ciliate moving

[Music]

just practice photosynthesis but they

don't have roots or leaves one common

example is algae some algae is

unicellular but kelp is an algae and is

very large other plant-like protists

include googly annoyed which move with a

flagella plankton and diatoms which look

like glass and finally some protists are

fungus like these protists are

decomposers common examples are slime

molds and water modes so there you have

a quick overview of kingdom Protista

kingdom fungi is made up of mushrooms

mold yeast and lichen fungi are very

important to life on Earth and many work

with plants in a symbiotic relationship

the following are some basic fungi facts

fungi have a nucleus and membrane-bound

organelles so they are considered

eukaryotic most fungi are heterotrophs

and get their energy from other

organisms most are unicellular but some

like yeast is unicellular

fungi cannot move about fungi may look

like plants but they are not plants and

they are different from plants in

several ways

almost all fungi do not have chlorophyll

so they cannot practice photosynthesis

they reproduce with spores not seeds

many fungi have cell walls made of

chitin instead of cellulose like plants

molds have cell walls of cellulose so

they earn our in exception many fungi

break down decaying matter and absorb

nutrients using a network of fibers

called - hi fear tube-like structures

that grow and cover a food source which

allows them to digest and absorb

nutrients many fungi like mushrooms have

a visible fruit which is easily seen and

a mass of - called a mycelium and most

likely this mycelium is hidden from view

there are four main types of fungi the

first is zygoma cotta and many of these

fungi are molds they produce spores on

the tips of their - a common example is

bread mold next our club fungi they have

a dome-shaped part where reproductive

spores are produced common examples are

mushroom next are sack fungi these fungi

produce reproductive spores in a sack

like structure common examples include

yeast mildew and lichen and finally you

have the imperfect fungi

this group is like your junk drawer of

fungi the fungi they don't really really

fit anywhere else go here however each

of these fungi reproduce asexually

athlete's foot is an example and finally

fungi can reproduce both sexually and

asexually thanks for watching and I hope

to talk about the animal kingdom the

kingdom Animalia is made up of many

organisms we encounter daily your pet

dog belongs to this kingdom along with

fish cats humans and many other types of

animals there is a very wide range of

animals in this kingdom but all animals

have these common traits all animals are

eukaryotes

which means they all have a nucleus and

membrane-bound organelles they are all

multicellular organisms all are

heterotrophs or in other words they

cannot produce their own food they must

eat another organism and finally almost

all animals can move sponges some

sponges cannot move so that might be an

exception there are two major categories

of animals the vertebrates which have a

backbone and the invertebrates that do

not

invertebrates make up the largest amount

of animals on earth

they include sponges cnidarians which

have stinging cells such as a jellyfish

many types of worms in fact there's

thousands of species of worms Mull escs

which include a squid or octopus

arthropods which include the insects eat

I know terms which are starfish and sea

urchins vertebrates on the other hand

have a backbone examples include the

strange fish called Lancelot's and

lampreys many other types of fish and

fib Ian's such as this frog reptiles

which includes snakes many many birds

and even mammals which we are animals

are found on every continent on earth

and they have adaptations that help them

survive thanks for watching I hope that

helps with the animal kingdom and

remember moomoomath uploads a new math
