Standard SB1A Explain the role of cell organelles for both prokaryotic and eukaryotic cells… in maintaining homeostasis.

Two types of cells Prokaryotic Eukaryotic Single-celled organisms Has no nucleus No membrane-bound organelles Examples: Bacteria Viruses Multi-cellular Has a nucleus Membrane-bound organelles   Examples: Plants Animals Fungi

Think: How does each help the cell maintain homeostasis? Organelles Think: How does each help the cell maintain homeostasis?

Nucleus Controls the cell functions Contains DNA

Cell Membrane Controls what goes in to or out of the cell

Ribosomes Build proteins

Mitochondria Release energy for the cell

Endoplasmic Reticulum (E.R.) Can be rough (has ribosomes) or smooth Pathway for proteins to move through cell

Golgi Packs up proteins and sends them off.

Cell Wall Protects the cell, structure Not in animals, only plants and bacteria

Chromosomes Made of DNA Contain genetic information

Chloroplast Photosynthesis takes place here Makes food from solar energy

Lysosome Waste disposal

Vacuole Stores water Larger in plants
