Class Notes - Cells and Organelles

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

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

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

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

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

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

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

ER (Endoplasmic Reticulum) - Rough ER has ribosomes attached - Molecules move throughout ER - Molecules can be chemically packaged (modified) here

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

Golgi Body - Modifies, stores, and roots proteins - Chemically packaged molecules
