A View of the cells: Cell parts and organelles Cell Parts & Organelles Cell or Plasma Membrane Function(s) Animal Plant Bacteria APB maintains homeostasis (like a gate) Cell Wall PB supports and protects the cell (like the wall of a house) Cytoplasm APB Nucleus AP Nucleolus AP site of protein synthesis, suspends all of the organelles in the cell (like Jell-O or a factory) control center of the cell, contains the directions to make proteins (like a boss or the president) makes ribosomes (like a factory machine) Endoplasmic Reticulum-ER AP Rough ER: site of protein synthesis; Smooth ER: site of lipid and steroid synthesis Ribosomes APB Golgi Apparatus AP make proteins; can be found free in the cytoplasm or attached to rough ER modifies, sorts, and packs proteins into vesicles Vesicle APB sacs that transport materials to all parts of the cell Vacuoles APB temporary storage site for various materials Lysosomes AP Mitochondria AP gets rid of all cell waste because they contain digestive enzymes that breakdown material powerhouse of the cell, makes energy; has a double membrane Chloroplast P Cytoskeleton AP Microtubules & Microfilaments AP make up the cytoskeleton; tubes and fibers of proteins Centrioles and Centrosomes Flagella A/AP play a role in cell division; centrioles (A) and centrosomes (A & P) AB aid in locomotion and feeding; long, whip-like; usually found on unicellular organisms Cilia AB Pili B aid in locomotion and feeding; short, hair-like projections; usually found on unicellular organisms Used for sexual reproduction produces food: captures light energy and converts it into chemical energy forms the framework of the cell, highway system of the cell; made up of microfilaments & microtubules
