Explain different modes of asexual reproduction in plants.

Modes of reproduction that evolve only one parent is called Unisexual reproduction.

(a) Fission: The mode of reproduction in which unicellular organism split into two equal halves and produce new ones is called binary fission. For example, amoeba and bacteria

(b) Fragmentation: The mode of reproduction in which body of plant breaks up into smaller fragments and each fragment grows into a new individual is known as Fragmentation, e.g. Spirogyra, algae.

(c) Budding: The mode of reproduction in which small buds develop and get separated and matured into new organisms is called Budding. E.g. Yeast, Hydra, Bryophyllum.

(d) Spore formation: The mode of reproduction takes place by means of spores is called spore formation, e.g., algae and fungi

The spores are covered by thick walls that protect them until they come into contact with another moist surface and can begin to grow.
