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
Ribosomes synthesis proteins for export
ribosome both plant/animal *small bodies free or attached to E.R.
*made of rRNA and protein *synthesizes proteins
