Assertion and Reason_Fungi
Numerical
Assertion : The fungi are widespread in distribution and they even live on 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, fucoxanthin and phycoerythrin.
Correct Answer: C
Explanation:
Fungi are considered ubiquitous i.e., they occur in a variety of habitats. Most of them are moisture loving and terrestrial and few (e.g., Monoblepharis) are aquatic. Fungi may be epiphytic (i.e., live on plants e.g., Armillaria), saprophytic (i.e., grow in dead organic matter e.g., Mucor), symbiotic (i.e., live with association with other plants e.g., lichen, mycorrhiza) and predacious (e.g., Dactyldela) and parasitic (e.g., Erysipi) fungi are non-chlorophyllus i.e., devoid of chlorophyll hence cannot prepare their own food. They are heterotrophic and show absorptive type of nutrition.
