PROPOGATION

Slide 4

Asexual reproduction

The formation of new plants from the cells of a single parent is called asexual reproduction

Slide 5

ASEXUAL REPRODUCTION

BUDDING

FRAGMENTAT-ION

SPORE FORMATION

Slide 6

Budding

In this process ,a small bulb-like outgrowth called bud is formed formed from the cell.This bud keeps on increasing in size and forms an independent organism which separates from the parent.

Eg: yeast

Slide 7

Fragmentation

In this process, the adult organism just breaks up into two or more pieces called fragments. Each of these fragments grows up to become a new plant .It is common in spirogyra & fucus.

Slide 9

Spore Formation

Some plants like ferns and mosses multiply asexually through spores . Spores are microscopic single celled or several celled reproductive bodies that are protected by a thick wall . During favourable conditions these spores burst out of the thick wall, start multiplying, and grow into new plants.
