Contents & notes: what this topic covers

Under Transport i. determine the relationship between increase in size and, the JAMB Biology syllabus expects you to study:

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

Study notes & guidance

Study Transport i. determine the relationship between increase in size and using a recommended Biology textbook that follows the JAMB syllabus. Work through the contents listed above one by one, make brief notes in your own words, and then practise as many questions on this topic as you can — in Biology, understanding and steady practice matter far more than memorising. Use the objectives below as a checklist: if you can do each one confidently, you have mastered this topic.

Objectives — candidates should be able to

After studying Transport i. determine the relationship between increase in size and, you should be able to:

1. Determine the relationship between increase in size and complexity; and the need for the development of a transport system in plants and animals.
2. Determine the sources of materials and the forms in which they are transported.
3. Describe the general circulatory system
4. Compare specific functions of the hepatic portal vein, the pulmonary vein and artery, aorta, the renal artery and vein.
5. Identify the organs of the plant vascular system.
6. Understand the specific functions of the phloem and xylem.
7. Identify media of transportation (e.g., cytoplasm, cell sap, body fluid, blood and lymph)
8. State the composition and functions of blood and lymph
9. Describe diffusion, osmosis, plasmolysis and turgidity as mechanisms of transportation in organisms.
10. Compare the various mechanisms of open circulatory systems in animal, transpiration pull, root pressure and active transport as mechanisms of transportation in plants.

These objectives are from the official JAMB syllabus. Use them as a checklist — if you can do each one confidently, you have mastered this topic.
