Plant - Coggle Diagram
Plant
Structure of plant cells
cell wall
outer layer of the cell
made of cellulose
has primary and secondary layers
chloroplast
contains chlorophyl
contains green pigment
used to absorb sunlight for photosynthesis
amyloplast
found in storage tissues
produce and store starch
vacuole
to store nutrients
maintain water balance
biggest organelle in the cell
tonoplast
membrane surrounding vacuole
semipermeable
allows some things to pass through and get in the vacuole
plasmodesmata
connection between cells found in the pits
pits
pathways in between cells in order for plant cells to communicate with each other
middle lamela
cementing layer between cell walls
how plants and animal cells compare
plants have cell walls while animals dont
plants have permanent vacuole while animals dont
plants cells are more rigid than animal cells
plant cells have chloroplast while animals cells dont
animal cells have lysosome, centrosome, and centriole while plant cells dont
plant stem
sclerenchyma
for support
located in the outer part of the stem
long narrow cells
dead cell
xylem
transport cells
water conducting cells
dead sclerenchyma cells stacked on each other
allows water to be trasported from roots to leaves
phloem
trasnport cells
alive cells
transport product of photosynthesis to the entire plant
the importance of water and organic ions
water
water is neccessary for photosynthesis to happen
organic ions
nutrients from the ground
both are needed to produce the energy needed for the plant to grow
Strucutre of
polysaccharides starch
mixture of
amylose
amylopectin
cellulose
combiation of alpha and beta glucose
linked by 1-4 glycosidic bonds
secondary thickening
makes the cell hard and stronger
can be used by humans to make objects that requires something strong
