Sexual reproduction:-
1. It involves the fusion of the male and female gamete.
2. It requires two (usually) different individuals.
3. The individuals produced are not identical to their parents and show variations from each other and also, from their parents.
4. Most animals reproduce sexually. Both sexual and asexual modes of reproduction are found in plants.
5. It is a slow process.
Asexual reproduction:-
1. It does not involves the fusion of the male and the female gamete
2. It requires only one individual.
3. The individuals produced are identical to the parent and are hence, called clones.
4. Asexual modes of reproduction are common in organisms having simple organizations such as algae and fungi.
5. It is a fast process.
Vegetative propagation is a process in which new plants are obtained without the production of seeds or spores. It involves the propagation of plants through certain vegetative parts such as the rhizome, sucker, tuber, bulb, etc. It does not involve the fusion of the male and the female gamete and requires only one parent. Hence, vegetative reproduction is considered as a type of asexual reproduction.
