Jaringan Parenkim (Jaringan Tumbuhan )
Summary
TLDRIn this video, Yuningsih introduces the topic of parenchyma tissue in plants for grade 11 students. Parenchyma, also known as basic tissue, is present in most parts of the plant and is made up of large, living cells with a nucleus and many vacuoles. The video covers various types of parenchyma, including storage parenchyma (found in roots, tubers, and seeds), aerenchyma (found in water plants like lotus and water hyacinth), and other specialized forms like chlorenchyma and stellate parenchyma. Viewers are invited to like and subscribe for future content on plant support tissues.
Takeaways
- 🌱 The topic discussed is the parenchyma tissue in plants, which is a part of the Grade 11 curriculum.
- 🌿 Parenchyma is referred to as basic tissue because it is found in almost every part of the plant.
- 🌾 Parenchyma cells are living, large in size, and contain a nucleus and many vacuoles.
- 🪴 These cells have intercellular spaces, so they are not closely packed together.
- 🍃 Parenchyma has meristematic properties, meaning the cells can actively divide.
- 🥔 The first type of parenchyma mentioned is storage parenchyma, found in organs like tubers, roots, rhizomes, and seeds.
- 💨 The second type is aerenchyma, which stores air and is found in plants like lotus leaves and water hyacinth.
- 🌞 Mesophyll tissue contains palisade and spongy parenchyma, which have chlorophyll, so they are called chlorenchyma.
- ⭐ Another type is actinenchyma, whose star-shaped cells connect at the tips, found in plant petioles.
- 📚 The next topic in the lesson will be supportive tissues in plants.
Q & A
What is parenchyma tissue in plants?
-Parenchyma tissue is the basic tissue in plants, found in almost every part of the plant body. It consists of living cells that are large, have a nucleus, and many vacuoles.
Why is parenchyma tissue referred to as the 'basic tissue'?
-It is called the 'basic tissue' because it is found in almost every part of the plant body and forms the foundation for other plant tissues.
What are the characteristics of parenchyma cells?
-Parenchyma cells are living cells, large in size, with a nucleus, many vacuoles, and they have spaces between them, making their arrangement less dense.
What is the function of parenchyma tissue in plants?
-Parenchyma tissue has multiple functions, such as storing food, gases, or water, and it can also perform photosynthesis when it contains chlorophyll.
What is storage parenchyma?
-Storage parenchyma refers to parenchyma tissue that has large vacuoles for storing food reserves, typically found in parts like tubers, roots, rhizomes, and seeds.
What is aerenchyma tissue and where is it found?
-Aerenchyma is parenchyma tissue specialized for storing air, characterized by large intercellular spaces. It is found in aquatic plants like water lilies and water hyacinths.
What are the two types of mesophyll parenchyma in leaves?
-The two types of mesophyll parenchyma are palisade parenchyma and spongy parenchyma, both of which contain chlorophyll and are involved in photosynthesis.
What is chlorenchyma and what is its function?
-Chlorenchyma is parenchyma tissue that contains chlorophyll, which allows it to perform photosynthesis.
What is actinenchyma and where is it found?
-Actinenchyma is a type of parenchyma tissue with star-shaped cells that connect at their tips, commonly found in the petioles of leaves.
What will be the next topic after the discussion of parenchyma tissue?
-The next topic will cover supporting tissues in plants.
Outlines
🌱 Introduction to Parenchyma in Plants
The speaker introduces the topic of parenchyma tissue in plants, focusing on its importance as fundamental tissue. Parenchyma is present in almost every part of the plant body and consists of living cells that are large, have a nucleus, and contain many vacuoles. The cells have intercellular spaces, making them loosely packed. This tissue is meristematic, meaning it can actively divide.
🍽️ Storage Parenchyma for Food Reserves
The first type of parenchyma discussed is storage parenchyma, which is responsible for storing food reserves. These cells contain large vacuoles to store nutrients. Examples include storage in structures like tubers, roots, rhizomes, and seeds.
🌬️ Aerenchyma: Air Storage Parenchyma
Aerenchyma is a specialized type of parenchyma that stores air and has large intercellular spaces. This type of tissue is found in aquatic plants such as lotus leaves and water hyacinth (Eichhornia crassipes), allowing the plants to float.
☘️ Mesophyll: Photosynthetic Parenchyma
In the mesophyll layer of leaves, there are two types of parenchyma: palisade parenchyma and spongy parenchyma. Both contain chlorophyll and are involved in photosynthesis, which is why this type of parenchyma is also called chlorenchyma.
⭐ Stellate Parenchyma: Actinenchyma
Actinenchyma is a type of parenchyma with star-shaped cells that are interconnected at their tips. This structure is found in the petioles (leaf stalks) of certain species and provides mechanical support.
🌿 Conclusion: Parenchyma Overview
The speaker concludes the discussion on parenchyma tissues, summarizing the different types: storage parenchyma, aerenchyma, chlorenchyma, and actinenchyma. The video promises to cover supporting tissues in plants in the next segment and encourages viewers to like and subscribe for future content.

Highlights
Introduction to the lesson on plant parenchyma tissues for 11th-grade students.
Parenchyma tissue is referred to as the 'basic tissue' because it is found in almost every part of a plant's body.
Parenchyma tissue consists of living cells, which are large in size and contain a nucleus and many vacuoles.
These cells have intercellular spaces, meaning the cells are not tightly packed together.
Parenchyma tissue is meristematic, meaning it has the ability to divide actively.
The first type of parenchyma tissue mentioned is storage parenchyma, which contains large vacuoles for food storage.
Examples of storage parenchyma can be found in tubers, roots, rhizomes, and seeds.
The second type is aerenchyma, a parenchyma tissue that stores air, with large intercellular spaces.
Examples of aerenchyma tissue include the leaves of lotus plants and the water hyacinth (Eichornia crassipes).
Mesophyll parenchyma, which is found in leaves, includes both palisade and spongy parenchyma.
Parenchyma tissue that contains chlorophyll is referred to as chlorenchyma.
Another type of parenchyma tissue mentioned is actinenchyma, which consists of star-shaped cells that are connected at their points.
Actinenchyma tissue is commonly found in the petioles of leaves.
The lesson concludes with an overview of parenchyma tissue and a teaser for the next topic on supporting tissues in plants.

Hai Hai assalamualaikum warahmatullahi
wabarakatuh ketemu lagi dengan saya web
id Yuningsih kali ini kita akan membahas
materi kelas 11 yaitu tentang jaringan
parenkim pada tumbuhan disimak baik-baik
ya jaringan parenkim atau yang bisa kita
sebut sebagai jaringan dasar Kenapa
disebut jaringan dasar karena hampir
dijumpai di setiap bagian tubuh tumbuhan
jaringan parenkim terdiri dari sel hidup
yang berukuran besar selnya memiliki
inti sel dan banyak vakuolanya jaringan
parenkim memiliki ruang
parcel sehingga letak File tidak rapat
jaringan parenkim bersifat meristematis
atau aktif membelah sekarang kita
bicarakan tentang macam-macam jaringan
parenkim yang pertama adalah jaringan
parenkim penyimpan cadangan makanan
[Musik]
jaringan ini memiliki vakuola yang besar
karena untuk menyimpan cadangan makanan
contohnya ada pada umbi akar rimpang dan
biji jaringan Parenkim yang kedua adalah
aerenkim aerenkim adalah parenkim
penyimpan udara memiliki ruang antarsel
yang besar contohnya pada daun teratai
pada eceng gondok atau eichornia
crassipes
Kau macam jaringan Parenkim yang lain
ada pada mesofil daun yaitu adanya
parenkim palisade dan parenkim spons
parenkim Ini mengandung klorofil makan
namanya klorenkim selanjutnya macam
jaringan Parenkim yang lain kalau tadi
kita sudah membicarakan klorenkim
parenkim berklorofil aerenkim parenkim
penyimpan udara nah ini ada aktinenkim
Parenkim yang sel-selnya berbentuk
bintang yang saling bersambungan
dibagian ujungnya terdapat pada tangkai
daun karena spesies nah selesai sudah
pemaparan tentang jaringan parenkim pada
tumbuhan
Hai selanjutnya kita akan membahas
jaringan penyokong pada tumbuhan
Ditunggu ya Jangan lupa like dan
subscribe ya terima kasih saya minta
maaf Wassalamualaikum warahmatullahi
wabarakatuh
