(a) A comparison of the vascular systems of animal groups: Insects - open circulatory system, dorsal tube shaped heart, lack of respiratory gases in blood. Vascularisation of earthworm, closed circulatory system and pumps, carriage of respiratory gases in blood.
(b) Mammalian circulatory system- double circulatory system compared with single circulation in the fish. The names of the main blood vessels associated with the human heart. Structure and function of heart and blood vessels. The cardiac cycle and the maintenance of circulation to include graphical analysis of pressure changes. Role of sinoatrial node and Purkinje fibres.
(c) The function of red blood cells and plasma in relation to transport of respiratory gases, dissociation curves of haemoglobin of mammal (adult and fetus). Dissociation curves of animals adapted to low oxygen level habitats e.g. Llama, lugworm. Bohr effect and chloride shift. Transport of nutrients, hormones, excretory products and heat. The formation of tissue fluid and its importance in exchange.
(d) Structure of the dicotyledon root. Absorption of water. Movement of water through the root: apoplast, symplast and vacuolar pathways. Structure and role of endodermis. The structure of xylem. Movement of water from root to leaf. Transpiration stream, cohesion-tension theory. Environmental factors affecting transpiration. Angiosperm adaptations: hydrophytes, xerophytes
(e) The structure of phloem as seen by the light and electron microscope. Translocation of organic materials from source to sink. Phloem transport: diffusion; cytoplasmic strands; mass flow models. Experimental evidence that solutes e.g. sucrose, are carried in the phloem. Use of aphids and autoradiographs.

Revision Powerpoint and revision workbook for plant biology
Note this includes aspects of 2.2 and 2.4 as well as 2.3. It's basically all the plant stuff that we've covered on my side of the course.
