Asexual reproductions in plants are of three types.
(a) Budding: In this process, a bud which is small, bulb like structure grows on the outer part of the cell, which after developed, gets detached from the parent cell forming an independent organism. Yeasts multiply by this method.
(b) Fragmentation: In this process, the parent body breaks up into two or more fragments, which later on, grows to become a new plant. Spirogyra and Fucus follow this type of reproduction.
(c) Spore formation: Some plants contain spores as reproductive bodies, which are surrounded by a thick wall. When there is a favourable condition for germination, these spores bursts out of thick wall, multiplies and grows into new plants. Ferns and mosses reproduce by this method.
