Read the passage and answer the following questions . In the process of sexual reproduction in angiosperms, the seed serves as the final product. It is formed from a fertilized ovule and is typically enclosed within a fruit. A seed is composed of several parts, including seed coats, cotyledons, and an embryo axis. The cotyledons of the embryo are simple structures that are often thick and swollen, storing food reserves, particularly in legumes. Mature seeds can be classified as albuminous (with endosperm) or ex-albuminous (with reduced endosperm). The integuments of the ovules harden to become protective seed coats, and a small pore called the micropyle remains, enabling the entry of oxygen and water during seed germination. As the ovules develop into seeds, the ovary undergoes transformation into a fruit. This simultaneous process involves the ovules turning into seeds, and the ovary walls developing into the fruit's pericarp. Fruits come in different types, including fleshy fruits like guava, orange, and mango, as well as dry fruits such as groundnut and mustard. Many fruits have evolved mechanisms for the dispersal of seeds. |
The wall of the ovary develops into : |
Fruit Pericarp Seed None of these |
Pericarp |
The correct answer is Option (2) : Pericarp During the maturation process, as the ovules develop into seeds, the ovary of the flower undergoes a transformation and develops into a fruit. This simultaneous process occurs in angiosperms, where the ovules and ovary transform into seeds and fruit, respectively. The wall of the ovary, which initially encloses the ovules, undergoes significant changes and forms the wall of the fruit. This transformed ovary wall is referred to as the pericarp. The pericarp is composed of three distinct layers: the exocarp, mesocarp, and endocarp. These layers can vary in thickness, texture, and composition, depending on the type of fruit. Overall, as the ovules mature into seeds, the ovary undergoes a transformation into a fruit, with the ovary wall becoming the pericarp. The pericarp consists of the exocarp, mesocarp, and endocarp, which collectively contribute to the structure, protection, and dispersal of the seeds within the fruit. |
