Revision checklist SB2 SB2 Cells and control SB2a Mitosis Step Learning outcome Had a look Nearly there Nailed it! List the names and order of the stages of the cell cycle, including mitosis.    Describe what happens in each stage of the cell cycle, including mitosis.    Describe why mitosis is important for an organism. (growth, repair, asexual    reproduction) Explain why organisms may rely on asexual reproduction.    Describe how mitosis produces genetically identical, diploid cells.    Describe how cancers grow.    SB2b Growth in animals Step Learning outcome Had a look Nearly there Nailed it! Define growth in animals as an increase in cell number and size.    Give examples of specialised animal cells.    Describe how structure of specialised animal cells is related to their function.    Explain why cell differentiation is important in the development of specialised cells.    Use percentile growth curves to interpret growth in children.    SB2c Growth in plants Step Learning outcome Had a look Nearly there Nailed it! Describe the stages of growth in plants (cell division/mitosis, elongation, differentiation).    Give examples of specialised plant cells.    Describe how the structures of specialised plant cells are related to their functions.    Explain why cell differentiation is important in the development of specialised cells in plants.    © Pearson Education Ltd 2016.

Describe where stem cells are found.    Describe the function of stem cells in plants and animals.    Compare embryonic and adult stem cells in animals.    Give examples of where stem cells may be used in medicine.    Identify benefits and risks of using stem cells in medicine.    Evaluate the use of stem cells in medicine (by comparing their benefits and risks).    SB2e The brain Step Learning outcome Had a look Nearly there Nailed it! Describe what the brain is made up of.    Identify different parts of the brain (cerebellum, cerebral hemispheres, medulla    oblongata). Describe the functions of different parts of the brain (cerebellum, cerebral hemispheres,    medulla oblongata). SB2f Brain and spinal cord problems Step Learning outcome Had a look Nearly there Nailed it! H Describe CT and PET scanning.    H Explain how brain function is studied using scanning, and the advantages of this    H Explain the effects of spinal cord damage.    H Explain the effects of damage to different parts of the brain (including tumours).    H Explain the limitations of brain surgery.    H Explain why some types of spinal cord damage cannot be fully repaired    © Pearson Education Ltd 2016.

List the parts of the nervous system.    Describe how the nervous system detects stimuli.    Describe the structure of sensory neurones.    Describe the routes that impulses take to and from the brain.    Explain how sensory neurones are adapted to their functions (including the myelin sheath).    SB2h The eye Step Learning outcome Had a look Nearly there Nailed it! Identify the main parts of the eye.    Explain how the cornea, lens, iris and retina are adapted to their functions.    Explain how receptor cells allow full colour vision in bright light.    Describe common eye defects (cataracts, long-sightedness, short-sightedness, colour    blindness). Describe how cataracts are treated.    Explain how long- and short-sightedness can be corrected.    SB2i Neurotransmission speeds Step Learning outcome Had a look Nearly there Nailed it! Describe how the nervous system responds to stimuli.    Describe the structures of motor neurones and relay neurones.    Explain how motor neurones are adapted to their functions.    Explain the action and function of synapses.    Explain how the structure of the reflex arc allows a faster response.    Describe the structure and function of the reflex arc.    © Pearson Education Ltd 2016.
