Ans. The stem supports the leaves and flowers of the plant and also transports water and nutrients throughout the plant.
Q178. What is the function of the leaves?
Ans. The leaves are responsible for photosynthesis, which provides food for the plant. Leaves also help to regulate temperature and transpiration (the process by which water vapor escapes from plants).
Q179. What is the function of the flowers?
Ans. The flowers of a plant are responsible for reproduction. The pollen from the male flower will fertilize the ovules in the female flower, which will then develop into seeds.

Q186. What is a flowering plant?
Ans. A flowering plant is a plant that produces flowers. Flowers are the reproductive organs of the plant, and they are typically showy or brightly colored in order to attract pollinators.
Q187. What is the purpose of flowers?
Ans. Flowers are the reproductive organs of plants, and their primary purpose is to facilitate reproduction. Pollination is necessary for fertilization to take place, and without it, seeds cannot be produced and the plant cannot reproduce.
Q188. How do flowers produce seeds?
Ans. After pollination occurs and pollen grains land on the stigma of a flower, they germinate and grow a tube called a pollen tube down the length of the pistil. The pollen tube eventually reaches the ovule, and the male gametes are released into the ovule where fertilization takes place.

Ans. There are four main types of simple fruits: drupes, pomes, berries, and true fruits. Drupes have a hard pit surrounding the seed, such as in the case of peaches and plums. Pomes have fleshy tissue surrounding a central core, such as in the case of apples and pears. Berries have thin skin and fleshy pulp, such as in the case of grapes and tomatoes. True fruits develop from the ovary and surrounding tissue, such as in the case of bananas and coconuts.
