biology (cell structure and cell function)

• Plasm membrane


  • regulates the movement of substance across the cell
  • seperates the contents of the cell from external enviroment
• Cell Wall

  • maintains its shape of plant cell
  • protects the plant cell from burst
  • provieds strength and support to the plant cell
• Cytoplasma

  • acts as a medium for biochemical reactions of most living processes in the cell
• Nuclues

  • carries genetic information in form of a DNA
• Vacuole

  • stores nutrien , waste and metabolic by-product
• Ribosome

  • synthesis protiens
• Mitochondria

  • synthesis ATP
  • site of cellular respiration
• Rough endoplasmic reticulum

  • transport proteins made by the ribosomes throughout the cell
• Smooth endoplasmic reticulum

  • synthesises lipids and carries detoxicfication of drugs
• Golgi appratus

  • modifies , transport , sort and packages protien and carbohydrates
• Lysosome

  • digest old and worn organelles
• Chloroplast

  • site of photosynthesis
• Centriole
