Prokaryote Eukaryote Animal cells (5) Plant cells Small, simple, unicellular cell, no nucleus Eg. Bacteria. Capsule Cell wall Plasma membrane Ribosomes Plasmid Cytoplasm Nucleus Complex, contains nucleus, all animal or plant cells. A Typical Eukaryote Cell DNA Ribosomes CHARLO Golgi Body Cell Membrane תי nucleus -holds genetic information and controls activities of all sub cellular structres Lysosome Nucleus cytoplasm-Gel-like substance where most of the chemical reactions take place and have enzymes which control these reactions Nucleolus. Nuclear Membrane Bacterial Flagellum Nucleoid (circular DNA) cell membrane- Control what goes in and out of the cell mitochondria- where aerobic respiration takes place. Respiration transfers energy needed for the cell to work Vacuole ribosomes- Where the proteins are made in cell.
