Correct Option
The correct matching is A-4, B-1, C-3, D-2.
- Fruit (A) develops from the ovary (4) of a flower after successful pollination and fertilization. The ovary wall matures into the pericarp of the fruit.
- Seed (B) develops from the ovule (1) after fertilization. The ovule contains the embryo and nutritive tissue, enclosed within protective seed coats.
- Wood (C) is primarily formed from the secondary growth of the stem (3) in woody plants. It consists mainly of secondary xylem, providing structural support and water conduction.
- Starch (D) is the primary storage carbohydrate synthesized in the leaves (2) of plants during photosynthesis. It is stored in chloroplasts and other plastids.
Incorrect Options
- Option (a) is incorrect because it incorrectly matches Fruit with Leaf and Starch with Ovary. Fruits originate from ovaries, and starch is synthesized in leaves.
- Option (c) is incorrect as it misassociates Fruit with Leaf, Seed with Stem, Wood with Ovule, and Starch with Ovary. Each of these pairings is biologically inaccurate regarding origin or primary function.
- Option (d) is incorrect because it incorrectly matches Seed with Stem and Wood with Ovule. Seeds develop from ovules, and wood is a product of stem growth.
