Question

Choose the correct statements among the following
I. Diplo haplontic life cycle can be seen in Bryophyte.
II. In Volvox, meiosis in zygote results in haploid spore.
III. Cycas has siphonogamous oogamy.
IV. Mycorrhizal association can be seen in Cycas roots.

• A. I and II
• B. II and III
• C. I and III
• D. III and IV

Hint:

Focus on examples like Volvox for zygotic meiosis and Cycas for siphonogamy while distinguishing life cycles of plants.

Answer 1

The Correct Option is B

II) Correct — Volvox is a green alga that shows zygotic meiosis leading to haploid spores.
III) Correct — Cycas has siphonogamy, where the male gamete is carried through a pollen tube.
I) Incorrect — Bryophytes exhibit haplodiplontic, not diplontic or diplohaplontic life cycles.
IV) Incorrect — Mycorrhizal association is found in higher plants like Pinus, not typically in Cycas.
