Excretion: JAMB Biology Past Questions and Answers
What the JAMB syllabus covers in Excretion
Our summary: The excretory structures from contractile vacuole to kidney, how kidneys, lungs and skin excrete, and plant excretory products.
- Types of excretory structures (Contractile vacuole, flame cell, nephridium, Malpighian tubule, kidney, stoma and lenticel.)
- Excretory mechanisms ((i) Kidneys; (ii) lungs; (iii) skin.)
- Excretory products of plants
Objectives
- define the meaning and state the significance of excretion
- relate the characteristics of each structure with functions.
- relate the structure of the kidneys to the excretory and osmo-regulatory functions.
- identify the functions and excretory products of the lungs and the skin.
- deduce the economic importance of the excretory products of plants e.g. carbon (IV) oxide, oxygen, tannins, resins, gums, mucilage, alkaloids etc.
