Asexual reproduction

Asexual reproduction

Earlier we saw that plants reproduce not only from seeds but by other processes as well. The production of new plants without the involvement of pollination and fertilization is knows as asexual reproduction. Let us know the types of asexual reproduction.

1. Vegetative Propagation

In potato, shoot arise from eyes. Sugarcane, yam are also grown like this. Vegetative parts of the plants such as root, stem and leaves can help to propagate the plant.

2. Budding

When we go to a bakery we see so many types of cakes and breads. These are very soft in nature. This is due to the presence of Yeast. Single yeast undergoes asymmetric division. It produces a small protuberance which gradually grows and detaches from the parent cell. This process is called budding.

4. Fragmentation

In a pond we see so many algae. Spirogyra is a filamentous alga, when it matures, the filament divides into pieces. Each fragment or piece of a filament will grow into a new filament or individual. Likewise Spirogyra produces so many young ones and this process is known as fragmentation.

5. Spore Formation

What do you mean by unfavourable conditions? Scarcity of water, high temperature, nutrient deficiency in soil etc.,  are unfavourable conditions. During these conditions non-flowering plants like Algae, Fungi, Moss and Ferns produces spores. They germinate into a new plant when favourable conditions are returns.
