Question

Plant group with largest ovule, largest tree, and largest gametes is

• A. gymnosperm
• B. angiosperm
• C. bryophyta
• D. pteridophyta.

Answer 1

The Correct Option is A

The question is asking which plant group is characterized by having the largest ovule, largest tree, and largest gametes. Let's analyze each of the options given:

1. Gymnosperm: Gymnosperms are a group of seed-producing plants that includes conifers, cycads, Ginkgo, and gnetophytes. They produce seeds that are not enclosed in an ovary (hence "naked seeds"). Gymnosperms have some of the largest features in the plant kingdom, including the largest ovule and some of the largest trees, such as the Giant Sequoia (Sequoiadendron giganteum) and the Coast Redwood (Sequoia sempervirens). Additionally, gymnosperms have large male gametes, especially in cycads. Thus, this option aligns well with the characteristics mentioned in the question.
2. Angiosperm: Angiosperms are flowering plants that produce seeds enclosed within a fruit. While they have many significant and biologically diverse groups, they are not known for having the largest ovules, trees, or gametes when compared to gymnosperms.
3. Bryophyta: Bryophytes include mosses, liverworts, and hornworts. These are non-vascular plants that do not form seeds and are much smaller in stature compared to gymnosperms and angiosperms. Therefore, they do not have the largest ovules, trees, or gametes.
4. Pteridophyta: Pteridophytes are vascular plants that do not produce seeds and instead reproduce via spores. They include ferns and their allies. Like bryophytes, they are not recognized for having the largest reproductive structures.

Based on this analysis, the correct answer is gymnosperm, as they exhibit the specified characteristics of having the largest ovule, largest tree, and large gametes.
