Q2 / 120 · NEET 2011 (Mains) · Botany
Consider the following four statements whether they are correct of wrong.
I. The sporophyte in liverworts is more elaborate than that in mosses
II. Salvinia is heterosporous
III. The life-cycle in all seed-bearing plants is diplontic
IV. In Pinus male and female cones are borne on different tress
- AStatements (I) and (III)
- Correct answerBStatements (I) and (IV)
- CStatements (II) and (III)
- DStatements (I) and (II)
Solution
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 sporophyte 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 monoecious plant in which male and female cones are borne on different branches of the same plant.
Hence, the correct answer is option: 'B'.
