Transport: JAMB Biology Past Questions and Answers

What the JAMB syllabus covers in Transport

Our summary: Why organisms need transport, what is carried, and the channels, media and mechanisms in animals and plants.

• Need for transportation
• Materials for transportation (Excretory products, gases, manufactured food, digested food, nutrient, water and hormones.)
• Channels for transportation ((i) Mammalian circulatory system (heart, arteries, vein and capillaries); (ii) Plant vascular system (phloem and xylem).)
• Media and processes of mechanism for transportation

Objectives

• determine the relationship between increase in size and complexity; and the need for the development of a transport system in plants and animals.
• determine the sources of materials and the forms in which they are transported.
• describe the general circulatory system
• compare specific functions of the hepatic portal vein, the pulmonary vein and artery, aorta, the renal artery and vein.
• identify the organs of the plant vascular system.
• understand the specific functions of the phloem and xylem.
• identify media of transportation (e.g. cytoplasm, cell sap, body fluid, blood and lymph)
• state the composition and functions of blood and lymph
• describe diffusion, osmosis, plasmolysis and turgidity as mechanisms of transportation in organisms.
• compare the various mechanisms of open circulatory systems in animal, transpiration pull, root pressure and active transport as mechanisms of transportation in plants.
