Key concepts

• what are Eukaryotic cells

  plants, fungi, animals and protists
• what are Prokaryotic cells

  bacterial cells
• what does an animal cells contain

  cell membrane

  cytoplasm

  nucleus

  ribosomes

  mitochondria
• what does a plant cell contain

  permanent vacuole

  chloroplasts

  cell wall

  cell membrane

  ribosomes

  mitochondria

  cytoplasm

  
• what does a bacteria cell contain

  cytoplasm

  cell membrane

  cell wall

  plasmid-small rings of DNA

  flagella-used for movement

  
• what is the function of cell membrane

  to control what enters and leaves the cell (selectively permeable)
• what is the function of cytoplasm

  Where chemical reactions take place
• what is the function of a nucleus

  Contains the cell's genetic material.
• what is the function of ribosomes

  Make proteins (protein synthesis)
• what is the function of mitochondria

  makes energy for the cell (aerobic respiration)
• what is the function of permanent vacuole

  stores water and helps support the cell
• what is the function of chloroplasts

  To make food through photosynthesis, and contains chlorophyll
• what is function of cell wall

  to protect and support the cell
• what is a specialised cell

  A cell which has adapted unique features to perform its function
• how are sperm cells specialised


  long tail - allows sperm cell to travel towards the egg cell quickly

  middle section - filled with lots of mitochondria to provide the sperm with energy

  nucleus - carries one half of an organisms genetic material

  acrosome - contains enzyme needed to break into an egg cell
