cell biology

• what are the two types of eukaryotic cell?

  Animal and plant
• what type of cell are bacteria?

  Prokaryotic
• where is the DNA found in animal plant cells?

  nucleus
• what's the function of the cell membrane?

  Controls movement of substances in and out of cell
• what is the function of the mitochondria?

  Site of respiration to transfer energy for the cell
• what is the function of chloroplasts?

  Contains chlorophyll to absorb light energy photosynthesis
• what is the function of ribosomes

  Protein synthesis
• what was the function of the cell wall?

  Strengthens and support cell
• what is the structure of the main genetic material in a prokaryotic cell?

  Single loop of DNA
• how are electron microscopes different to light microscopes?

  Electron microscopes use of electrons instead of light they cannot be used to view living samples and much more expensive have a much higher magnification and resolution
• what's the function of red blood cell?

  Oxygen transport
• give three adaptations of red blood cell

  No nucleus contains haemoglobin and has a biconcave shape
• what is the function of the nerve cell?

  Carry electrical impulses around the body
• give two adaptations of a nerve cell

  Branched endings to connect to other neurons and a myelin sheath insulate the axon
• what is the function of the sperm cell?

  Fertilising an egg
• give two adaptations of a sperm cell

  Tail and lots of mitochondria
• what is the function of the palisade cell?

  Carry out photosynthesis in the leaf
• give two adaptations of a palisade cell

  Lots of chloroplasts located at the top surface of the leaf
• What is the function of the root hair cell?

  Absorb minerals and water from the soil
• give two adaptations of a root hair cell

  Long projection and lots of mitochondria
