Question

Assertion : Algae and fungi are classified as thallophytes.

Reason: They both are autotrophs

(a) Both A and R are true and R is the correct explanation of A.

(b) Both A and R are true but R is not correct explanation of A

(c) A is true but R is false

(d) A and R are false

Answer 1

The correct option is: (c)

Explanation:

According to Eichler's classification, plant kingdom is divided into two subdivisions cryptogamae and Phanerogamae. Cryptogamae has 3 divisions thallophyta, bryophyta and Pteridophyta. Thallophya in turn is divided into 2 classes. algae and fungi. As both these groups have generally undifferentiated plant body (not differentiated into true root, stem and leaves) they are called thallophyta. Also. they are non vascular plants. But algae are chlorophyllous and hence show autotrophic mode of nutrition i.e. can prepare their own food. But fungi are non-chlorophyllous and cannot prepare their own food. So they are heterotrophic in nature.
