Study notes & guidance

Study Internal structure of a flowering plant 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 Internal structure of a flowering plant, you should be able to:

1. Identify the transverse sections of these organs.
2. Relate the structure of these organs to their functions.
3. Identify supporting tissues in plants (collenchyma) sclerenchyma, xylem and phloem fibres)
4. Describe the distribution of supporting tissues in roots, stem and leaf
5. Examine the arrangement of the mammalian internal organs.
6. Describe the appearance and position of the digestive, reproductive and excretory organs.

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.
