Transcripts

all right you are watching this video

because you have chosen um the Palisade

cell as your cell for your cell project

so this presentation is going to be an

overview of the Palisade cell remember

that this is just an overview so after

this you should go to padlet and here is

some of the resources that are already

available to you that will give you more

in-depth information about Palisade

cells as well as your textbook and of

course you are um expected to do some of

your own research as well and if you

find any great resources please be sure

to post them here on the padlet for

Palisade

cells okay Palisade cells what is a

palisade cell a palisade cell is a leaf

cell um it's a very specific type of

leaf cell so if we look here at this

picture of a tree

we have a leaf and I've blown that up

here's your Leaf we know that leaves are

very flat so here is a cross section of

the leaf so if you took this and just

that thin thin layer the thickness that

thin thickness going up and down of the

leaf right here would go

here and right here are our Palisade

cells so here are one two three Palisade

cells that we have shown in this

picture notice that Palisade cells we

saw in the previous picture they look

kind of like bricks they're they're

they're kind of boxy in shape these this

is one Palisade cell that I am outlining

look how similar that looks to bricks on

a wall and I want you to think why might

that be what how might it help the plant

as a whole the tree as a whole that

these Palisade cells are shaped and laid

out just like the bricks to a wall what

might that help with or allow the plant

to be able to

do the function of a palisade cell is of

course to make food for the plant so

we're going to take that tree example

these cells are the food makers for the

tree they are near the outside of a Leaf

as we saw here see how they're near the

outside of this Leaf they're not in the

middle they're not in the bottom they're

right up here near the surface and that

is to get a bunch of

sunshine they make sugar doing

photosynthesis from that Sunshine so

they use the sun's energy to make sugar

but they also do need some of the energy

from the cell which is also something I

want you to think about what might that

mean is inside a palisade cell if it

needs energy in order to do this

photosynthesis also photosynthesis

occurs in chloroplasts we can see

several chloroplasts here this green

color inside these chloroplasts is

called

chlorophyll chlorophyll is a type of

protein also something I want you to

think about chlorophyll is a type of

protein so what does that mean about

what is inside that Palisade

cell in order to do photosynthesis we've

got a picture of it right here and the

chemical equation that occurs so we've

get the sun of course and then this

chemical reaction is what is happening

inside one chloroplast and there are

there's more than one chloroplast inside

a palisade cell there is carbon dioxide

it reacts with water and using that

sun's energy and a little bit of the

plant's energy it will create

glucose which is sugar which is food for

the plant and then oxygen is a byproduct

and that oxygen is what we breathe

in this is a picture of where do all

these ingredients for photosynthesis

come so carbon dioxide is coming in from

the air we breathe it out the plants

absorb it in through their leaves so

they have special structures on

different cells of the leaf to take in

that carbon

dioxide higher concentration oops sorry

higher concentration out here lower

concentration in here we also get water

water is coming up from the roots it is

traveling up to the leaves so again I

want you to think where is the higher

concentration where is the lower

concentration because that's a process

for how these Palisade cells that are in

this Leaf right here get these

ingredients in order to make sugar which

is food and then the

oxygen okay that's kind of it so these

are some things I want you to think

about how does the shape and layout of a

palisade cell help it do its

job in order to complete photosynthesis

the Palisade cell needs energy and

chlorofil and that should give you an

idea of what organel are in abundance

here remember also that chlorophyll is a

protein okay then finally how does the

plant get those needed ingredients to

complete

photosynthesis what process would bring

these ingredients to the Palisade cell

and of course again remember this is

just that brief over you to get your

brain started thinking about what a

palisade cell is how some of its basic

structures and its processes you do need

to go to that padlet to do more to get

more information and then of course do

some more of your own research if you

find any great resources be sure to um

post it on that padlet for your fellow

class classmates to take advantage of

and of course if you have any question
