REVIEW OF CELL ORGANELLES
Organelles Common to Prokaryotes and Eukaryotes
CELL WALL
Made of various materials. In plants, CELLULOSE. Provides
support, shape, and acts as a barrier
CELL MEMBRANE
Composed of fats and protein
-1o barrier between the cell and the environment
- embedded proteins perform transport, enzyme,&
communication functions
RIBOSOMES
The organelle of Protein Synthesis
FLAGELLA
Responsible for moving the cell
Organelles found ONLY in Eukaryotes - most are MEMBRANE-BOUND
NUCLEUS
Membrane bound region-contains chromosomes & nucleolus
NUCLEOLUS
in Nucleus - Ribosome assembly
CHROMOSOMES
contain DNA packaged with proteins
ENDOPLASMIC
RETICULUM:
"inside the cell network" - membrane-bound network inside the
cell connecting the cytosol, nucleus, and the golgi complex
ROUGH . . . . . . . . . . . . . . .
studded with ribosomes
transport and modify proteins made by the ribosomes
SMOOTH . . . . . . . . . . . . . .
modification of proteins and production of new membrane
GOLGI COMPLEX
Modification and packaging of proteins for use within the cell or
for export from the cell - membrane bound
VACUOLE (P)
Membrane bound sac - contains mostly water
LYSOSOME
Membrane bound sac - contains digestive enzymes
PEROXISOME
Membrane bound sac - contains detoxifying enzymes
MITOCHONDRIA
Energy factory - converts stored energy into usable energy Membrane-bound
CHLOROPLAST(P)
Energy factory - converts radiant energy into chemical energy
(sugars) - Membrane-bound
CYTOSKELETON
Composed of microtubules & microfilaments - CELL
SCAFFOLDING
Responsible for cell shape and movement of and within cell
CILIA
Responsible for cell movement, feeding and creating “current”
around the outside of the cell
