Distinguish between the following pair of terms: (a) Egg and sperm. (b) Sexual reproduction and asexual reproduction. (c) Budding and Regeneration.

(a) Egg and sperm 

Egg Sperm 

1. Egg is produced in the ovaries. 

2. Egg is spherical in shape with a nucleus. 

Sperm 

1. Sperm is produced in the testes. 

2. Sperm has head with nucleus, middle piece and tail. 

(b) Sexual reproduction and asexual reproduction. 

Sexual reproduction 

1. In sexual reproduction the two sexes i.e., male and female produce special type of reproductive cells sperms in the male and eggs in the female. 

2. To produce a new individual the sperm has to reach the ovum and fuse with it. e.g. Humans, bird, reptile, etc. 

Asexual reproduction: 

1. It involves the production of an offspring from a single parent without the fusion of reproductive cells (gametes). 

2. It is a rapid mode of multiplication, e.g. Lower plants and animals {Amoeba). 

(c) Budding and Regeneration 

Budding: Budding is a process in which buds grow on the outside of the parent body. The buds detach themselves when they are large enough. Example: Hydra 

Regeneration: Regeneration is the process that uses cell division to regrow lost body parts. 

Example: Starfish, sponges
