Plant and Animal Cells

• Cell


  The very smallest unit of living matter. All living things, including plants and animals, are made up of cells.
• Cell


  A cell is like a chemical factory. There are many different kinds of cells, doing many different jobs in a plant or animal.
• Organelle identification


  Watch the video and list as many organelles as you can
• In reality, most cells are much more complicated than this!
• Similarities between plant and animal cells

  Both have a nucleus, cytoplasm, cell membranes, and mitochondria
• Differences between plant and animal cells

  Plant cells also have a cell wall, chloroplasts, and a vacuole
• Respiration


  Both cell types can respire (due to the presence of mitochondria)
• Photosynthesis


  Only plant cells can photosynthesis (due to the presence of chloroplasts)
• In that same minute, about three billion cells divided so that all the cells that died were replaced.
• Like all living things, cells die. If you watched a clock for one minute, about three billion cells in your body die.
• Dead skin cells flake off and dead cells from internal organs will pass through and out of the body with waste products.
• Cell lifespan


  • White blood cells: 13 days
  • Red blood cells: 120 days
  • Liver cells: 18 months
  • Nerve cells: 100 years
• Organelles


  • Vacuole
  • Cell membrane
  • Cell wall
  • Mitochondria
  • Nucleus
  • Chloroplast
  • Cytoplasm
