Transcript of Organelles

Cell Wall
Thick fibers that protect the cell and give it shape
Plasma Membrane
Function: flexible boundary that controls the movement of substances into and out of cell
Cytoplasm
Function: Semi-fluid material inside the cell
Is the site of most cellular activity
Ribosomes
Site of Protein synthesis
Found in cytoplasm & Rough ER
Nucleus
Function: Control center which contains coded directions for protein production and cell division

Contains DNA for coding proteins

Endoplasmic Reticulum
Golgi Apparatus
Function: modifies proteins and other cellular materials and packages them for distribution outside the cell
Vacuole
Function: membrane bound vesicle used for storage, usually water, salts, and wastes

Tend to be found in
Plants (larger)

Lysosome
A vesicle that contains digestive enzymes for the breakdown of excess or worn-out cellular substances.

Clean up Crews
Mitochondria
Produce most of the energy needed to carry out the cell’s functions (jobs).

Take fuel particles (sugars such as glucose) and break them into smaller particles releasing energy in the process.

Carbon Dioxide is the waste product
Chloroplast
A double-membrane organelle with thylakoids containing chlorophyll where photosynthesis takes place.

Site of Photosynthesis
And now a video.....
Cytoskeleton
Function: Fibers that support and give shape to the cell
Semi-permeable or Selectively Permeable
Function: Highly folded membrane:
Can have ribosomes attached & is the site of protein production (Rough ER)

Can provide storage and transportation of proteins and lipids (Smooth ER)
Outside the cell
Found in Plants
