Write a short note on spore formation. (OR) How spores are produced in sporangia of fungi? |
|
Answer» 1. Spore formation is a method of asexual reproduction which occurs through microscopic reproductive units called spores. 2. Most of the fungi like rhizopus, mucor etc., bacteria and non-flowering plants such as ferns and mosses reproduce by the method of spore formation. 3. In fungi like rhizopus spores are produced in some specialised structures called sporangia which bursts and spreads the spores into air. These spores when fall on food or soil under favourable conditions germinate and produce new plants. 4. In non-flowering plants like fern, the leaves called sporophyll bears clusters of sporangia on their lower side. These sporangia produce the spores which produce the new plant when it falls on ground under favourable conditions. |
