Question

Some organisms suspend their metabolic activities to survive in unfavourable conditions. Explain with the help of any four examples.

Answer 1

• Some microbes like bacteria, fungi and lower plants produces thick walled spores which helps them to survive in unfavourable condition.
• Higher plants produces seeds which reduces metabolic activity and remain dormant in stress condition but they start germination in favourable conditions.
• In animals some species migrate, some hibernate and some aestivate to overcome the unfavourable conditions.
• Some aquatic organisms enters into diapause during unfavourable conditions e.g., zooplanktons.
