Science

• Vacuole (Animal cell)

  • A space within a cell
  • Stores a liquid, food and waste materials
  • Small and numerous
• Cytoplasm

  • Jelly-like substance that fills a cell
  • Site where most chemical reactions take place
  • Both Animal and Plant cells has Cytoplasm
• Nucleus

  • Centre that controls all activities that occur within a cell
  • Contains deoxyribonucleic acid (DNA) - the hereditary or genetic material in living things passed down from parents to offspring.
  • Both Animal and Plant cells has Nucleus
• Cell membrane

  • Thin outer layer that surrounds a cell
  • Controls the movement of substances in and out of a cell
  • Layer below the cell wall in the Plant cell
  • Both Animal and Plant cells has Cell membrane
• Cell wall

  • Tough outer covering surrounding the cell membrane in a Plant cell
  • Protects and supports the entire cell
  • Rigid and gives the cell a regular shape
  • Allows a substance to move into and out of the cell
  • Unlike Animal cells, Plant cells has Cell wall
• Chloroplast

  • "Food factory" in a Plant cell
  • Allows photosynthesis to take place
  • Unlike Animal cells, Plant cells has Chloroplast
• Vacuole (Plant cell)

  • A space within a cell
  • Stores liquid, food and waste materials
  • Large and few
• Unicellular organism

  A single-celled organism that is not a plant or animal.
• Multicellular organism

  An organism that has more than one cell.
• Root Hair cells.

  • Lack of Chloroplast.
  • Absorbs water from soil by Osmosis.
• Organisation.

  Cell: Root Hair cells have a specific function. -> Tissue: Root Hair cells make up the Root tissue. They perform the same function of absorbing water and mineral salts. -> Organ: Root is an organ made up of different tissues that work together to perform the same function of absorbing water and mineral salts. -> System: Transport system of a plant is made up of different organs, such as the root and the stem. Works together to perform the specific function of transporting substances around the plant.
• Red blood cells.

  • Appears pale due to the absence of nuclei.
  • Transports oxygen from the lungs to the body.
