This is a PowerPoint on Cell OrganellesTRANSCRIPT
Cell Organelles
What you need to know
An organelle is a membrane-bound structure that carries out
specific activities for the cell.
You will need to know the following organelles and their function:
Cell Membrane Nucleus
Cytoplasm Mitochondria Golgi Complex Ribosomes
Smooth Endoplasmic Reticulum Rough Endoplasmic Reticulum
Cell Wall Chloroplast
Central Vacuole Lysosome
Cell Membrane
Every cell is enclosed by a cell membrane. It controls the passage of materials in and out of the cell.
Nucleus
The control center of the cell. It contains the DNA code for the cell coiled into chromosomes.
Cytoplasm(not an organelle - but important)
All organelles reside (live and float around in) the cytoplasm.
Mitochondria
This organelle processes energy for a cell. It makes ATP.
(ATP = energy) Involved in cellular
respiration.
Golgi Complex
The protein packaging and transport center of the cell.
Has incoming and outgoing vesicles.
Ribosomes(not an organelle - but important)
Synthesizes proteins. Present in the
cytoplasm. Present with Rough ER. No membrane present.
Smooth Endoplasmic Reticulum
Transports materials throughout the cell.
Digests lipids. Produces proteins.
QuickTime™ and aTIFF (Uncompressed) decompressor
are needed to see this picture.
Rough Endoplasmic Reticulum
Covered with ribosomes.
Produces proteins. Transports materials
throughout the cell.
Lysosome
Breaks down materials for digestion.
Contains special enzymes for digestion in the cell.
Cell Wall (Plant Cell Only)
Rigid and strong wall.
Protects and maintains the shape of the cell.
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)
Most plant cells have one large one.
Filled w/ fluid. Helps maintains
turgor pressure and shape of cell.
