ORGANELLE LOCATION DESCRIPTION FUNCTION
cell wall plant, fungi and bacteria but
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
All cells *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
nucleus is absent in
prokaryotic cells
both plant/animal
*large, oval generally
. *controls cell activities
*key organelle which has the genetic material and is
involved in multiplication of cell, growth and maintenance
of cell.
nucleolus All cells except prokaryotes
*Found inside cell’s nucleus
* may have more than one
*disappears during cell division
* Make ribosomes, contains building blocks or mRNA,
tRNA, rRNA
nuclear membrane both plant/animal *surrounds nucleus
*selectively permeable *Controls movement of materials in/out of nucleus
Centrioles Animal cells *paired structures near the nucleus
*made of cylinder of microtubule pairs *stparate chromosome pairs during mitosis
cytoplasm both plant/animal
All cells *clear, thick, jellylike material
(sytosol)
* organelles found inside cell
membrane
*contains cytoskelon fibers
*supports /protects cell organelles
endoplasmic
reticulum (E.R.)
Smooth
Rough
both plant/animal *network of tubes or membranes
No ribosomes
Attached ribosome
*carries materials through cell
Synthesis of fats/lipids

These are the vacuoles or sac like* to modify and package proteins for exportstructures. They occupy a considerablehave cis and trans faceamount of cytoplasm.stacks of flattened sacs vacuole^ plant - few/largeanimal - small

fluid-filled sacs^ * Vacuoles are pouches in the cell that store materials suchas water, salts, proteins, and carbohydrates, waste productsand toxic waste..store food, water, waste (plants need to store large amountsof food) Vesicles^ A lot of small bubble sacs inanimals, large sac in themiddle of plant cells

These are small-sized sac like*These help in storage and release of substances as requiredstructures. They are of different typesby the cell. For example lysosomes help in cell digestionlysosomes, peroxisomes.when cell dies. Vacuoles function is to store water. lysosome^ plant - uncommonanimal - common
