Question

During unfavourable conditions slime molds form spores which are survival for a long time, spore dispersal take place by

• A. Water currents
• B. Air currents
• C. Insects
• D. None of these

Answer 1

The correct option is A Water currents

• Slime moulds are Saprophytic Protists.
• They move along decaying twigs and leaves engulfing organic material.
• Under a suitable condition, they form aggregation called Plasmodium.
• During unfavourable condition, the plasmodium differentiates and form fruiting bodies bearing spores at their tips.
• The spores possess true walls.
• They are extremely resistant and survive for many years even under adverse conditions.
• The spores are dispersed by air currents.
• So, the correct answer is 'Air currents'.
