B) Flower
C) Root
D) Ovary

Answer 1

Hint: Fruits are juicy, pulpy, coloured, an aromatic structure that contains seeds and are a rich source of vitamins, minerals and fibres. Grapes, bananas, papaya, watermelon are some of the fruits which are consumed by humans and are the main source of a balanced diet. A fruit comprises of two parts the pericarp and the seeds.

Complete answer:
Now let us look into the given explanation to get the correct answer:
A) Leaf: Leaves contain chlorophyll that helps the plants to make their food using sunlight, carbon dioxide and water. It consists of three main parts namely, petiole, leaf base and lamina.
B) Flowers: Flowers are the most beautiful and colourful part of the plant. They are the reproductive part of a plant. A flower has four major parts, namely, petals, sepals, stamen and pistil.
C) Roots: Roots are the most important and the underground part of a plant, which are together called the root system. They are the major part that anchors the plant firmly in the soil and thereby absorb water and minerals from the soil, makes plant growth regulators, and stores reserve food material. The apical part of the root is covered by the root cap which protects the root apex.
D) Ovary: Fruits are the mature ovary or the ovaries of one or more flowers. Fruits are produced only by the flowering plants which are called the angiosperms. Following pollination of the flower, the fertilized ovules transform into seeds while the surrounding ovary wall develops into the fruit tissue or pericarp.

Therefore the correct answer is option ‘D’.

Note: Based on the number of ovaries and the number of flowers involved in the fruit formation, fruits are classified into three groups like simple fruits which are further classified into drupes, berries, pomes and hesperidium and pepos, the second classification is aggregate fruits and finally, composite fruits that are of two types sorosis and syconus.
