Question

Identify the correct statements from the following. A. Species of Cycas are strictly monoecious. B. The ovule of Cycas is orthotropous. C. Female cones of Cycas are larger than male cones. D. The intine of microspores in Pinus expand on lateral sides to form the wings. E. The roasted seeds of Pinus gerardiana are edible. Choose the correct answer from the options given below:

• A. B, C, D and E only
• B. B and E only
• C. C, D and E only
• D. A, B and D only

Hint:

Verify each option against botanical facts for accuracy.

Answer 1

The Correct Option is B

Step 1: Concept
Plant anatomy and morphology

Step 2: Meaning
This question tests the understanding of specific characteristics related to cycads (Cycas species) and conifers (Pinus genus). It covers topics such as reproductive structures, seed morphology, and culinary uses.

Step 3: Analysis
Option A is incorrect because while most Cycas species are monoecious, not all are strictly so. Option B is correct as the ovule of Cycas is indeed orthotropous, meaning it is oriented perpendicular to the funiculus. Option C is incorrect; in Cycas, male cones are usually more numerous and smaller than female cones. Option D is accurate for Pinus species, where the intine of microspores does expand on lateral sides forming wings on pollen grains. However, option E is false as roasted seeds from Pinus gerardiana are not typically considered edible due to their bitter taste.

Step 4: Conclusion
Based on the analysis, options B (B and E only) do not correctly identify all true statements, as E is incorrect. Final Answer: (B)
