animal and plant cells structures and functions
Show Answers:

  1. Cells Membrane
    • Cell Membrane
    • Structure- Outer flexible membrane composed of lipids and phosphates
    • Function- Allows certain materials to enter and leave cell, support and protect cells.
  2. Nucleus
    • Nucleus
    • Structure: membrane bound structure inside cell filled with chromatin (DNA)
    • Function: Controls the production of proteins. Directs cell activities
  3. Ribosome
    • Ribosome
    • Structure: small particles of RNA and protein found throughout the cytoplasm.
    • Function: Site of protein synthesis. Produce proteins.
  4. Endoplasmic Recticulum
    • Endoplasmic Reticulum
    • Structure: Two forms of internal membrane systems. Rough and Smooth. Rough has ribosomes attached to it. Folded network
    • Function: workspace to assemble lipids and proteins.
  5. Golgi Apparatus
    • Golgi Apparatus
    • Structure: stack of closely connected membranes.
    • Function: modifies sorts and transports proteins and other materials around the cell.
  6. Vacuoles
    • Vacuoles
    • Structure: saclike structures filled with liquid.
    • Function: store materials such as water, salts, carbohydrates and proteins.Call vesicles in animal cells and much smaller.
  7. Mitochondria
    • Mitochondria
    • Structure: membrane bound structure with folded inner membranes.
    • Function: convert energy stored in food to usable cellular energy, power house.
  8. Chloroplast
    • Chloroplast
    • Structure: membrane bound structure found only in plants.
    • Function: capture the energy from the sun and convert it into glucose (chemical energy)
  9. Cytoskeleton
    • Cytoskeleton
    • Structure: network of tubes and filaments that are in cytoplasm or outside of cells.
    • Function: Used to maintain shape and cell movement.
  10. Centrioles
    • Centrioles
    • Structure: Found in animal cells only, rod shaped structures near the nucleus
    • Function: help organize cell division
  11. Lysosome
    • Lysosome
    • Structure: membrane bound organelle filled with digestive enzymes.ANIMAL CELLS ONLY
    • Function: digestion and breakdown of lipids and carbohydrates and proteins into smaller cells and also involved in getting rid of old, dead cells.
  12. Cell wall
    • Cell Wall
    • Structure: Rigid outer layer in plants only.Outside cell membrane
    • Function: Provides additional support and protection.
  13. Cytoplasm
    • Cytoplasm
    • Structure: Jelly like substance found throughout the cell.
    • Function: site of all chemical reactions, used to support organelles in cell.
