Question

Select the correct combination of the statements (1- 4) regarding characteristics of pteridophytes.

(1) They are the first group of plants to possess vascular tissues.

(2) Their gametophytes are differentiated into true roots, stem and leaves.

(3) The dominant phase in the life cycle is sporophyte.

(4) Unlike bryophytes, they do not require water for the process of fertilization.

• A. 3 and 4
• B. 1 and 2
• C. 2 and 4
• D. 1 and 3

Answer 1

The correct option is D

1 and 3

Pteridophytes are the first group of plants to possess vascular tissues (xylem and phloem). Therefore statement 1 is correct.

Gametophytes in pteridophytes are short-lived, small, inconspicuous, multicellular and independent. It is thalloid - undifferentiated into root, stem and leaves and is referred to as prothallus. Therefore, statement 2 is incorrect.

The diploid sporophyte is dominant in pteridophytes. Therefore, statement 3 is correct.

Pteridophytes, similar to bryophytes, require water for fertilisation. Therefore, statement 4 is incorrect.
