| (c) | Funaria | (iii) | Dominant diploid sporophyte alternating with reduced gametophyte called prothallus |
| (d) | Cycas | (iv) | Dominant haploid leafy gametophyte alternating with partially dependent mutlicellular sporophyte |
Choose the correct answer from the options given below:
Assertion (A): Bryophytes are the amphibians of the plant kingdom.
Reason (R): They are found in swamps and areas, where water and land meet.
(A) Elaters
(B) Indusium
(C) Agar
Assertion (A): In evolution, the distribution of Bryophytes and Pteridophytes, was limited.
Reason (R) : The need for water for the transportation of male gametes and fertilization limited their distribution.
The correct option among the following is:
A) The female sex organs of Angiosperms are called strobilus.
B) The fusion of motile male gamete with non-motile egg is called zooidogamy.
C) Some algae are in association with animals.

Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : The first stage of gametophyte in the life cycle of moss is protonema stage.
Reason (R): Protonema develops directly from spores produced in capsule.
