  • Animal and Plant Cells
    • Cell Structure
      • NUCLEUS -  controls all activities of the cell
        • Contains chromosomes which carry genes that carry instructions for making new cells and organisms.
      • CYTOPLASM - Chemical reactions take place here.
        • a liquid gel in which the organelles are suspended
      • CELL MEMBRANE - controls passage of substances in and out of cell
      • MITOCHONDRIA -     where  aerobic respiration occurs
        • Releases energy for the cell
      • RIBOSOMES - where protein synthesis takes place.
    • Plant Cells only
      • CHLOROPLASTS - Absorbs light so plant can make food by photosynthesis.
        • contain green substance chlorophyll.

        • RIBOSOMES - where protein synthesis takes place.
      • VACUOLE - keeps cells rigid for plant support
        • filled with cell sap
      • CELL WALL - made of cellulose that strengthens and supports plant.
    • Eukaryotic Cells
      • Complex and include animal and plant cells
      • Organisms made up of Eukaryotic cells
      • They have  1.Cell membrane 2.Cytoplasm 3.Genetic information enclosed in a nucleus.
    • Prokaryotic Cells
      • Smaller and simpler eg bacteria. Single-celled organisms.
      • Cytoplasm and cell membrane surrounded by cell wall (not made of cellulose)
      • Genetic material found in single DNA loop
      • May contain small rings of DNA called plasmids code for antibiotic resistance
      • They have no nucleus, they have a single strand of DNA in the cytoplasm
