Answer 2

Answer:

In simple words this is known a asexual reproduction in plants

Explanation:

You might have heard about that if we want to grow a new rose plant we can cut it half from a particular spot and plant it. The part which was cut will eventually grow into a new plant  Some plants, like ferns and mosses, grow from spores. Other plants use asexual vegetative reproduction and grow new plants from rhizomes. We can also use techniques like grafting or take cuttings to make new plants. Basically to grow potato we dont need seed. As you might have observed that potato have some dark spots and some buds on them. the buds sooner or later eventually develop into a potato plant. Then the only thing you have to do is plant it.

Conclusion - Plants dont always need seeds to grow there are many other ways we can grow them. Basically "Asexual Reproduction in plants".
