Living Cells
Introduction
The structure and function of a variety of cells including plant, animal and microbial cells should be studied so that candidates can appreciate that cells are functional living units. While specialised cells can be used to exemplify variety, the detailed structure and function of these should be dealt with in the context of other units, eg in Animal Physiology.

a) Cell structure and function
i Similarities and differences between
animal, plant and microbial cells.
Cheek epithelial cells, leaf mesophyll cells and
yeast cells should be used to illustrate typical
plant, animal and microbial cells, their similarities
and differences in structure.
Examine fresh and prepared slides of a range of
plant, animal and microbial cells using appropriate
stains and a light microscope. Suitable examples
would include: cheek epithelium, onion epidermis,
rhubarb epidermis, Elodea, yeast.
ii Function of cell structures. Functions of nucleus, cytoplasm, cell membrane,
cell wall, chloroplasts and vacuole.
iii Commercial and industrial uses of cells.
Bread making. Anaerobic respiration in yeast produces carbon
dioxide gas which causes dough to rise.
Select and present data on the commercial and
industrial uses of micro-organisms.
Alcohol production. Fermentation in yeast results in the production of
alcohol (beer and wine).
