Class Notes - Cells and Organelles

Lysosome

Uses digestive enzymes to break down large molecules- Recycles damaged organelles.

Cytoplasm

Transport- Clear fluid within cell that contains all organelles- Moves materials through the cell- Various chemical reactions happen here- Digestion.

Chloroplast

Site of Photosynthesis- Converts light energy into chemical energy- Found only in plant cells.

Golgi Body

Modifies, stores, and roots proteins- Chemically packaged molecules.

Ribosome

Synthesis- Makes proteins in the cell- May be free in cytoplasm or attached to ER (rough ER)

Mitochondria

powerhouse of the cell- respiration- releases energy from nutrient molecules.

Nucleus

Regulation- Controls most activity in the cell- Contains genetic information in the form of DNA- DNA has instructions for making proteins.

cell membrane

Separates from outer environment- Outer boundary of the cell- Controls what enters and leaves the cell- Also known as the plasma membrane

Vacuoles

Store food, water, or waste products- Plants have large vacuoles.

Cell wall

Only found in plant cells- Adds protection and support- Made of cellulose.
