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
