Asexual reproduction

• Does not involve the fusion of gametes.
• Requires only one parent.
• Offsprings produced are the exact copies of their parents.

Modes of asexual reproduction

• Fission- involves cell division or splitting of cells e.g., Amoeba
• Multiple fission: In multiple fission, a single cell divides into many daughter cells simultaneously. Examples:Plasmodium and Amoeba
• Fragmentation- new organisms formed from fragments of parents e.g., lichens
• Regeneration- new organisms formed from body parts e.g., Planaria, Hydra
• Budding- new individuals from protrusion called buds e.g., Hydra

Reproduction-It is the ability of living organisms to produce new individuals.

1. Asexual reproduction – New plants are formed without seeds or spores.
2. Sexual reproduction –  New plants are obtained from seeds.
