|| ======Covered in Class====== || ======Revised @ home====== || ======I am certain====== || ======I need help====== ||
 * ======**5.1 Transport in plants**====== ||
 * ====== 1  ====== || ======State the functions of xylem and phloem.====== ||   ||   ||   ||   ||
 * ====== 2  ====== || ======Identify the positions of xylem and phloem tissues as seen in transverse sections of unthickened, herbaceous, dicotyledonous roots, stems and leaves.====== ||   ||   ||   ||   ||
 * ====== 3  ====== || ======Identify root hair cells, as seen under the light microscope, and state their functions.====== ||   ||   ||   ||   ||
 * ====== 4  ====== || ======Relate the structure and functions of root hairs to their surface area and to water and======

ion uptake
||  ||   ||   ||   ||
 * ====== 5  ====== || ======State the pathway taken by water through root, stem and leaf (root hair, root cortex cells, xylem, mesophyll cells).====== ||   ||   ||   ||   ||
 * ====== 6  ====== || ======Investigate, using a suitable stain, the pathway of water through the above-ground parts of a plant.====== ||   ||   ||   ||   ||
 * ====== 7  ====== || ======Define //transpiration// as evaporation of water at the surfaces of the mesophyll cells followed by loss of water vapour from plant leaves, through the stomata.====== ||   ||   ||   ||   ||
 * ====== 8  ====== || ======Describe how water vapour loss is related to cell surfaces, air spaces and stomata.====== ||   ||   ||   ||   ||
 * ====== 9  ====== || ======Describe the effects of variation of temperature, humidity and light intensity on transpiration rate.====== ||   ||   ||   ||   ||
 * ====== 10  ====== || ======Explain the mechanism of water uptake and movement in terms of transpiration producing a tension (‘pull’) from above, creating a water potential gradient in the xylem, drawing cohesive water molecules up the plant.====== ||   ||   ||   ||   ||
 * ====== 11  ====== || ======Define //translocation// in terms of the movement of sucrose and amino acids in phloem; from regions of production to regions of storage OR to regions of utilisation in respiration or growth.====== ||   ||   ||   ||   ||
 * ======**5.2 Transport in humans**====== ||
 * ====== 1  ====== || ======Describe the circulatory system as a system of tubes with a pump and valves to ensure one-way flow of blood.====== ||   ||   ||   ||   ||
 * ====== 2  ====== || ======Describe double circulation in terms of a low pressure circulation to the lungs and a high pressure circulation to the body tissues and relate these differences to the different functions of the two circuits.====== ||   ||   ||   ||   ||
 * ====== 3  ====== || ======Describe the structure of the heart including the muscular wall and septum, atria, ventricles, valves and associated blood vessels.====== ||   ||   ||   ||   ||
 * ====== 4  ====== || ======Describe coronary heart disease in terms of the blockage of coronary arteries and state the possible causes (diet, stress and smoking) and preventive measures.====== ||   ||   ||   ||   ||
 * ====== 5  ====== || ======Describe the function of the heart in terms of muscular contraction and the working of the valves.====== ||   ||   ||   ||   ||
 * ====== 6  ====== || ======Investigate the effect of physical activity on pulse rate.====== ||   ||   ||   ||   ||
 * ====== 7  ====== || ======Investigate, state and explain the effect of physical activity on pulse rate.====== ||   ||   ||   ||   ||
 * ====== 8  ====== || ======Name the main blood vessels to and from the heart, lungs, liver and kidney.====== ||   ||   ||   ||   ||
 * ====== 9  ====== || ======Describe the structure and functions of arteries, veins and capillaries.====== ||   ||   ||   ||   ||
 * ====== 10  ====== || ======Explain how structure and function are related in arteries, veins and capillaries.====== ||   ||   ||   ||   ||
 * ====== 11  ====== || ======Identify red and white blood cells as seen under the light microscope on prepared slides, and in diagrams and photomicrographs.====== ||   ||   ||   ||   ||
 * ====== 12  ====== || ======List the components of blood as red blood cells, white blood cells, platelets and plasma.====== ||   ||   ||   ||   ||
 * ====== 13  ====== || ======State the functions of blood:======

carbon dioxide.
||  ||   ||   ||   ||
 * ====== 14  ====== || ======Describe the immune system in terms of antibody production, tissue rejection and phagocytosis.====== ||   ||   ||   ||   ||
