Animal cell
Take a moment to see how
the plant cell diagram
compares to the animal cell

Plant cell
Chloroplasts
(On sheet)
#10
• Name: Chloroplasts
• Function: to convert sunlight into energy for the cell

Chloroplasts (notes)
• Chloroplasts are what make plants their distinctive green color
• The process of turning light into energy is called photosynthesis
The green blobs you can
see in each of the cells are
chloroplasts
Cell wall (on sheet)
• Name: Cell wall
#11
• Function: rigid support, protection
The cell wall lies outside the
membrane
It is like a suit of armor worn
over the skin
Central vacuole
(On sheet)
• Name: Central vacuole
• Function: storage, support the cell with pressure
The central vacuole can take
up most of the space in a
plant cell
#12
Turgor pressure (not notes)
• Smaller plants (those without wood) use water pressure to hold their shape
• Unlike animal cells, the cell wall in plant cells keeps them from bursting when
water flows in
• The central vacuole is like a balloon full of water, pressing on the cell wall
• This is why plants wilt when they
are low on water
