Question

During unfavorable conditions, the plasmodium of slime moulds differentiates to form fruiting bodies bearing spores. What is a unique feature of these spores?

Options

Choose one · Correct answer highlighted

They possess true walls and are extremely resistant. Correct They lack a cell wall entirely and are fragile. They use flagella to swim toward decaying matter. They germinate into photosynthetic structures.

Explanation

When conditions become unfavorable (like lack of moisture or food), the plasmodium of slime moulds differentiates and forms distinct fruiting bodies at its tips. According to the NCERT text, the spores produced within these fruiting bodies possess 'true walls'. This is crucial because it makes them extremely resistant to harsh elements, allowing them to survive for many years until conditions improve and they are dispersed by air currents.
