Cell Structure and Organisation
Be prepared to discuss:
(a) The internal membranes of eukaryotic cells and their importance. The structure of the following organelles: mitochondria; endoplasmic reticulum (rough and smooth); ribosomes; golgi body; lysosomes; centrioles; chloroplasts; vacuoles; nucleus; chromatin; nuclear envelope; nucleolus; plasmodesmata. The function of these organelles. Structure of prokaryotic cells and viruses. Comparison of cell structure of eukaryote, animal and plant, prokaryote and virus.
(b) Levels of organisation: aggregation of cells into tissues. Brief histology of: epithelium, cuboidal and ciliated; muscle, smooth and striated; connective tissue, collagen. Aggregation of tissues into organs.
