Water is not required for the act of fertilization in:

A

Cryptogams

B

Bryophytes

C

Spermatophyes

D

Pteriodophytes

Text Solution

Verified by Experts

The correct Answer is:
C
In spermatophytes, siphonogamy occurs where the male gametes are carried through the pollen tube and thus water is not required for the act of fertilization. In bryophytes and pteridophyte, male gametes are always motile and they swim in watery medium, thus water is essential for the act of fertilization.
