Syllabus content and objectives
Official JAMB Biology outline · B: Form and Functions
Content
Need for transportation in organisms; transported materials, including excretory products, gases, manufactured food, digested food, nutrients, water and hormones; relationship between increasing size and complexity and the need for transport systems.
Objective
Determine the relationship between increased size and complexity and the development of transport systems in plants and animals; identify sources of transported materials and the forms in which they are transported.
Content
Mammalian circulatory system: heart, arteries, veins and capillaries; functions of the hepatic portal vein, pulmonary vein and artery, aorta, renal artery and renal vein.
Objective
Describe the general circulatory system; compare the specific functions of the hepatic portal vein, pulmonary vein and artery, aorta, renal artery and renal vein.
Content
Plant vascular system: phloem and xylem; their roles in transportation.
Objective
Identify organs of the plant vascular system; explain the specific functions of phloem and xylem.
Content
Transport media and mechanisms, including cytoplasm, cell sap, body fluid, blood and lymph; composition and functions of blood and lymph; diffusion, osmosis, plasmolysis and turgidity; open circulatory systems in animals; transpiration pull, root pressure and active transport in plants.
Objective
Identify transport media; state the composition and functions of blood and lymph; describe diffusion, osmosis, plasmolysis and turgidity; compare mechanisms of open circulation in animals with transpiration pull, root pressure and active transport in plants.
