formation of thick walled spores.
D.
formation of thick walled spores.
Bacteria, fungi and lower plants survive in adverse conditions through formation of thick walled spores. Algae form resting spore or akinetes which are thick walled spores and store food material. In fungi, thick walled perennating spores called chlamydospores are formed. Bacteria form endospores which is probably the most resistant living thing known. They may remain alive in boiling water for more than 2 hours.
In a 50 gm living tissue, what would be the amount of water
15- 25 gm
25 - 30 gm
35- 45 gm
70- 90 gm
Cleistogamy is leading over anthesis because
pollination agent is not required
it assures heterozygosity
it favours insect pollination
it allows xenogamy
