What I need to be able to do…
Cell structure
Label an animal cell – Cell membrane, cytoplasm and
nucleus
Label a plant cell – Cell wall, cell membrane, cytoplasm,
nucleus, chloroplast and vacuole
State the function of all the parts of animal and plant
cells listed above
Identify the mitochondria and ribosomes in a cell diagram
Explain the function of a mitochondria and a ribosome
Label a bacterial cell and explain the differences between
it and other types of cell.
Label a fungal cell and explain the differences between it
and other types of cell.
Transport
Describe the structure of the cell membrane

enzyme are
Give 3 named examples of chemical reactions carried out
by enzymes and be able to draw the word equations
Explain how temperature effects enzyme activity
Explain how pH effects enzyme activity
Describe some uses of enzymes in industry e.g. Biological
detergents and rennet in cheese making

Describe what is meant by anaerobic respiration
Explain what the products of anaerobic respiration are in
humans and yeast
Explain how anaerobic respiration can be used to benefit
man (fermentation in yeast – breadmaking and brewing)

fixation) of photosynthesis
Label the parts of a leaf
Explain the role of the xylem and phloem
Explain what a limiting factor is
List the limiting factors for photosynthesis
