products are excreted

8. Growth
– basis of growth-cell
division (mitosis)
enlargement and
differentiation

– regulation of growth by
hormones

9. Cell reactions to its
environment
(i) Irritability as basic
characteristics of the
protoplasm
(ii) Types of responses

10. Movement:
(i) Cyclosis
(ii) Ogranelles for movement
(iii) Growth movement as
regulated by auxins

11. Reproduction:
Forms of reproduction

a. Asexual:
– Fission
– Budding
– Vegetative propagation

b. Sexual:
– Conjugation
– Fusion of male and female
gametes, meiosis, structure
and functions of the male
and female garments.
Sub-theme

2.Tissues &
Supporting
Systems
1. Skeleton and supporting
systems in animals:
– Biological significance
– Forms e.g. chitin, cartilages
and bones

2. Types of skeleton:
– Hydrostatic skeleton
– Exo-skeleton
– Endo-skeleton

3. Vertebrate skeletons:
– the skull
– sternum and ribs
– limb girdles
– limbs

4. Bones of the vertebral
column

5. Different types of supporting
tissues in plants:
– location and arrangement of
structural components.

6. Functions of skeleton in
animals
– protection
– support
– locomotion

7. Functions of supporting tissues
in plants:
– strength
– rigidity
