animal & plant cells

• components of both plant and animal cells:

  • nucleus
  • cytoplasm
  • cell membrane
  • mitochondria
  • ribosomes
• additional components of plant cells:

  • chloroplasts
  • permanent vacuole
  • cell wall
• function of nucleus

  contains genetic material that controls the activities of the cell
• structure and function of the cytoplasm

  • gel like substance where most of the chemical reactions take place
  • it contains enzymes that control these chemical reactions
• function of cell membrane

  • holds cell together
  • controls what enters and exits the cell
• function of the mitochondria

  • site of aerobic respiration
  • respiration transfers energy that the cell needs to work
• function of ribosomes

  • joins amino acids in a specific order during translation for synthesis of proteins
• function of chloroplasts

  • where photosynthesis takes place
  • contain chlorophyll which absorbs the light needed for photosynthesis
• structure and function of permanent vacuole

  • contains cell sap
  • supports the cell, maintaining its turgidity
• structure and function of cell wall

  • made of cellulose
  • strengthens the cell
