Correct option is D
Correct Answer: (4) A-ii, B-iii, C-i, D-iv
Explanation:
Let's match the plant types with their correct features:
A. Heteroblastic: This refers to plants that undergo morphological changes that take place with plant development (ii). Heteroblastic plants display different forms of leaves or other structures at different stages of their lifecycle, such as juvenile versus adult phases. These changes are part of their natural growth process.
B. Phanerogams: Phanerogams are plants that reproduce through well-developed sexual structures (iii). These plants have distinct, visible reproductive organs such as flowers (in angiosperms) or cones (in gymnosperms), which are involved in sexual reproduction.
C. Hemicryptophyte: Hemicryptophytes are plants that die back to near ground level at the onset of the unfavorable season (i). These plants have buds at or just below the soil surface, enabling them to survive harsh conditions such as winter and re-grow when the environment becomes favorable again.
D. Hermaphrodite: A hermaphrodite plant is one that has both male and female sex organs in the same flower (iv). These plants can self-pollinate or cross-pollinate within the same flower or between flowers of the same species.
Information Booster:
Heteroblastic (A): The term heteroblastic refers to the plant's ability to undergo changes in its form or structure, particularly at different stages of life. An example is the juvenile leaves of many tree species being different from adult leaves in shape and size.
Phanerogams (B): Phanerogams are flowering plants that are capable of sexual reproduction, with specialized reproductive structures (flowers or cones). This group includes both angiosperms (flowering plants) and gymnosperms (cone-bearing plants).
Hemicryptophytes (C): These plants are well-adapted to survive harsh conditions, such as extreme cold. They die back to near the ground level (their buds remain near the surface), allowing them to survive winter or drought and regenerate when conditions improve.
Hermaphrodites (D): Hermaphroditic plants have both male and female reproductive organs in the same flower. This adaptation allows them to reproduce sexually within a single individual, enhancing their chances of reproduction in some plant species.
