Animal/plant cell 1a

• Animal cell


  • Nucleus
  • Cell membrane
  • Cytoplasm
  • Mitochondria
  • Ribosomes
• Animal cells do not have a cell wall, large vacuole, or chloroplasts
• Plant cell


  • Cell wall
  • Large vacuole
  • Chloroplasts
• Plant cells have a cell wall, large vacuole, and chloroplasts, which animal cells do not have
• Nucleus


  Contains chromosomes which carry genetic information
• Cell membrane


  Holds the cell contents together, controls what goes in and out
• Cytoplasm


  Gel-like substance where reactions happen
• Mitochondria


  Where reactions for aerobic respiration happen
• Cell wall


  Made of cellulose, supports and strengthens the cell
• Large vacuole


  Has cell sap (sugar and salt), pushes against cell wall to firm the cell
• Chloroplasts


  Where photosynthesis happens, contain green chlorophyll that absorbs light
• Specialised cells have different subcellular structures and functions compared to unspecialised cells
• Specialised cells


  • Sperm cell - adapted to move fast, with many mitochondria to produce energy
  • Red blood cell - lost their nuclei and packed with haemoglobin
• Differentiation


  The process where a cell becomes specialised for its job
• what’s the meaning of multicellular

  complex organisms made of lots of cells
• The three main types of tissue are epithelial, connective and muscle tissue
• Muscle tissue contracts to produce movement.
• Meaning of differentiation 


  cells changing to become specialised
• What happens when cells become specialised

  They develop different sub cellular structures
• What 3 structures aren’t found in a animal cell

  Cell wall,large vacuole,chloroplasts
• What do cells make up

  living organisms
• What is the function of a nucleus?

  contains chromosomes that carry genetic information
• What is the function of the cell membrane?

  Holds the cell together and controls what goes in and out the cell
• What is the function of cytoplasm?

  Gel like substance, reactions take place here
• What respiration takes place in the mitrochindria?

  Aerobic respiration
• What does the cell wall contain and how does it help

  Contains cellulose which supports and strengthens the cell
• What does the large vacuole contain and how does it work?

  Cell sap which gets pushed to make the wall firm
• What does chloroplasts do?

  Contains chlorophyll to absorb light for photosynthesis.
