Question

Long answer questions
E. Answer in detail.
1. Write a short note on spore formation in
plants.​

Answer 1

In spore formation, the parent plant produces hundreds of microscopic reproductive units called ' spores'. When the spore case of the plant bursts, then the spores spread into air. When these air- borne spores land on food ( or soil ) under favourable conditions ( like damp and warm conditions) they germinate and produce new plants.

Spore formation is a method of asexual reproduction which is found in non flowering plants such as fungi (Rhizopus) and bacteria. In this method of reproduction, the parent plant produces hundreds of tiny spores which can grow into new plants.

(or)

The form of asexual reproduction in which the organism breaks down into no. of spores and later these spores develop into new organism is called spore formation.

For eg: Protozoa

Answer 2

Answer:

Spore Formation is a method in Asexual Reproduction. Many Spores are stored in sacs called Sporangia. When Sporangia burst; minute single-celled, thin or thick walled structures called spores are obtained. Under suitable conditions, they develop into a new Plant.

Reproducing using spores is an asexual method. The sporangia are knob-like structures. They are present at the top of the thread-like structures called hyphae. They are dispersive, i.e. they are scattered by rain, wind or insects.
