Which of the following is incorrect?a)Phanerogams contain specialized ...
Explanation:
Phanerogams and Cryptogams:
- Phanerogams are vascular plants that produce seeds and flowers, while cryptogams are non-vascular plants that reproduce by spores.
- Phanerogams have specialized reproductive organs like flowers and seeds, whereas cryptogams do not have these structures.
Gymnosperms and Angiosperms:
- Gymnosperms are a group of seed-producing plants with uncovered seeds, such as conifers, cycads, and ginkgoes.
- Angiosperms are flowering plants that produce seeds enclosed within a fruit, such as apple trees, roses, and grasses.
- Gymnosperms and angiosperms are two main groups of phanerogams based on the type of seed they produce.
Covered and Naked Seeds:
- Gymnosperms have uncovered or naked seeds, meaning the seeds are not enclosed within a fruit or ovary.
- Angiosperms have covered seeds, where the seeds are enclosed within a fruit or ovary.
Fruit Production:
- Angiosperms bear fruits as a part of their reproductive process. Fruits develop from the ovary of the flower after fertilization.
- Gymnosperms do not produce fruits; instead, they produce cones or other structures to house their seeds.
In conclusion, option C is incorrect because it states that gymnosperms have covered seeds, which is not accurate. Gymnosperms have naked seeds, while angiosperms have covered seeds enclosed within fruits.
