Activity 4.1:
Aim: To gather and interpret information about sexual and asexual reproductions
Instruction
1. Work in groups.
2. Discuss the differences and similarities between internal and external fertilisation.
3. Record your discussion in a table as below.
4. Collect information from the Internet on the following types of asexual reproductions:
(a) binary fission
(b) budding
(c) spore formation
(d) vegetative reproduction
(e) regeneration
Answer:
(a) Binary fission is the division of one parent cell to two daughter cells.
(b) Budding is a process of bud formation on the body of an organism. The bud starts off asa swelling. Then, it develops and breaks off as a new individual.
(c) Spore formation is a process of producing spores in the sporangium. After the sporangium splits, the tiny and light spores get scattered by the wind. When they land in a moist place, they grow into new plants.
(d) Vegetative reproduction is a method of producing new plants from a vegetative part of a plant except the flower.
(e) Regeneration occurs from the ability of the fragments of some organisms to grow and develop into completely new individuals.
