LOCATION |
DESCRIPTION |
FUNCTION |
cell wall
|
plant, not animal |
*outer layer
*rigid, strong, stiff
*made of cellulose |
*support (grow tall)
*protection
*allows H2O, O2, CO2 to pass into and out of cell |
cell
membrane |
both plant/animal |
*plant - inside cell wall
*animal - outer layer; cholesterol
*selectively permeable |
*support
*protection
*controls movement of materials in/out of cell
*barrier between cell and its environment
*maintains homeostasis |
nucleus
|
both plant/animal |
*large, oval |
*controls cell activities |
nuclear membrane |
both plant/animal |
*surrounds nucleus
*selectively permeable |
*Controls movement of materials in/out of nucleus
|
cytoplasm
|
both plant/animal |
*clear, thick, jellylike material and organelles
found inside cell membrane |
*supports /protects cell organelles |
endoplasmic
reticulum (E.R.) |
both plant/animal |
*network of tubes or membranes |
*carries materials through cell |
ribosome |
both plant/animal |
*small bodies free or attached to E.R. |
*produces proteins |
mitochondrion
|
both plant/animal |
*bean-shaped with inner membranes |
*breaks down sugar molecules into energy |
vacuole
|
plant - few/large
animal - small |
*fluid-filled sacs |
*store food, water, waste (plants need to store large
amounts of food) |
lysosome
|
plant - uncommon
animal - common |
*small, round, with a membrane |
*breaks down larger food molecules into smaller molecules
*digests old cell parts |
chloroplast
|
plant, not animal |
*green, oval usually containing chlorophyll
(green pigment) |
*uses energy from sun to make food for
the plant (photosynthesis) |
