Assertion : The fungi are widespread in distribution and they even live on or inside other plants and animals. Reason : Fungi are able to grow anywhere on land, water or on other organisms because they have a variety of pigments, including chlorophyll, carotenoids, fucooxanthin and phycoerythrin.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion
  3. CIf assertion is true but reason is false
  4. DIf both assertion and reason are false.

Correct answer

C. If assertion is true but reason is false

Step-by-step solution

Fungi are considered ubiquitous i.e. they occur in a variety of habitats. Most of them are moisture loving and terrestrial and few (eg. Monoblepharis) are aquatic. Fungi may be epiphytic (i.e. live on plants eg. Armillaria), saprophytic (i.e. grow in dead organic matter eg. Mucor), symbiotic (i.e. live with association with other plants eg. lichen, mycorrhiza) and predacious (eg. Dactyldela) and parasitic (eg Erysipi) fungi are achlorophyllus i.e. devoid of chlorophyll hence cannot prepare their own food. They are
