Question

Consider the following four statements whether they are correct or wrong.
(a) The sporophyte in liverworts is more elaborate than in mosses.
(b) Salvinia is heterosporous.
(c) The life-cycle in all seed-bearing plants is diplontic.
(d) In Pinus, male and female cones are borne on different trees.
The two wrong statements together are

• A. Statements (a) and (b)
• B. Statements (a) and (c)
• C. Statements (a) and (d)
• D. Statements (b) and (c)

Answer 1

The correct option is C Statements (a) and (d)

The sporophyte is more developed in mosses rather than liverwort. The simplest sporophyte is found in Riccia, a liverwort, where it is represented by capsule only. The most complex sporophye is found in Funaria, a moss. However, the most advanced sporophyte is found in Anthoceros (a hornwort) due to the presence of intercalary meristem. Pinus (a gymnosperm) is a monoecious plant in which male and female cones are borne on different branches of the same plant. Hence option C is correct.
