Cell Membrane : Cell Membrane Every cell is enclosed by a cell membrane. It controls the passage of materials in and out of the cell.
Nucleus : Nucleus The control center of the cell. It contains the DNA code for the cell coiled into chromosomes.
Cytoplasm(not an organelle - but important) : Cytoplasm(not an organelle - but important) All organelles reside (live and float around in) the cytoplasm.
Mitochondria : Mitochondria This organelle processes energy for a cell. It makes ATP.
(ATP = energy)
Involved in cellular respiration.
Golgi Complex : Golgi Complex The protein packaging and transport center of the cell.
Has incoming and outgoing vesicles.
Ribosomes(not an organelle - but important) : Ribosomes(not an organelle - but important) Synthesizes proteins.
Present in the cytoplasm.
Present with Rough ER.
No membrane present.
Smooth Endoplasmic Reticulum : Smooth Endoplasmic Reticulum Transports materials throughout the cell.
Digests lipids.
Produces proteins.
Rough Endoplasmic Reticulum : Rough Endoplasmic Reticulum Covered with ribosomes.
Produces proteins.
Transports materials throughout the cell.
Lysosome : Lysosome Breaks down materials for digestion.
Contains special enzymes for digestion in the cell.
Cell Wall (Plant Cell Only) : Cell Wall (Plant Cell Only) Rigid and strong wall.
Protects and maintains the shape of the cell.
Chloroplast(Plant Cell Only) : Chloroplast(Plant Cell Only) Contains chlorophyll.
Makes plants green.
Uses light energy to make ATP & sugars.
Photosynthesis takes place here.
Central Vacuole(Plant Cell Only) : Central Vacuole(Plant Cell Only) Most plant cells have one large one.
Filled w/ fluid.
Helps maintains turgor pressure and shape of cell.
