A1 - Cell Structure

Cards (16)

  • Function of Ribosomes
    • site of protein synthesis
    • contains RNA
  • Role of Golgi Apparatus
    • stores lipids proteins carbohydrates
    • makes vesicles
  • Role of Centrioles
    • involved in cell division
    • required for mitosis and meosis
  • Two Processes of Cell Division
    • Mitosis produces two cells that are identical
    • Meiosis produces four non identical cells
  • Describe Meosis
    • A process by which gametes are produced
    • The number of chromosomes is halved compared to normal cells
    • Haploid cells are produced
    • Four daughter cells are produced
  • Describe meosis
    • A process by which gametes are produced (1) 
    • The number of chromosomes is halved compared to normal cells (1) 
    • Haploid cells are produced (1) 
    • Four daughter cells are produced (1) 
  • Explain how cells divide for growth
    • By mitosis - producing daughter cells
    • Doubling the chromosomes then splitting them
  • Role of lysosomes
    • contains enzymes - for digestion
  • Function of Nucleolus
    • Makes Ribosomes
    • Produce RNA
  • 4 Parts of Nucleus
    • Nucleolus
    • Nuclear Envelope
    • Nuclear Pores
    • Chromatin DNA
  • Function of Mitrochondria
    • Aerobic respiration takes place
    • Releases energy
  • Function of Lysosomes
    • Destroy pathogens in cells
    • Release digestive enzymes from the cell
    • Break down waste materials
  • Function of Golgi Apparatus
    • Receives proteins from the RER
    • Produces lysosomes involved in lipid synthesis
  • Function of Rough Endoplasmic Reticulum
    • Provides a larger surface area for protein and glycoprotein synthesis
    • Provides a pathway for materials to be transported
  • Function of Smooth Endoplasmic Reticulum
    • Synthesises, stores, and transports lipids and carbohydrates
  • Function of Centrioles
    • involved in cell division
    • required for mitosis and meosis
