MCQs on Reproduction in Flowering Plants

Flowering plants or angiosperms reproduce sexually by the process known as pollination. In this process, the pollen from the male anther is transferred to the female stigma. These pollens travel through the pollen tube and produce gametes which fuse with the egg in the embryo sac. This gives rise to fruit.

9.The male reproductive parts of a flower, the stamens, are collectively known as:

(a) Androecium

(b) Filament

(c) Anther

(d) Gynoecium

Answer: (a)

The male reproductive parts of a flower are collectively known as the androecium. It consists of the anthers and filaments. The anthers are the pollen-producing structures, and the filaments are the stalks that support the anthers.

10.The female reproductive parts of a flower, the carpels, are collectively known as:

(a) Androecium

(b) Filament

(c) Anther

(d) Gynoecium

Answer: (d)

The female reproductive parts of a flower are collectively known as the gynoecium. It consists of the stigma, style, and ovary. The stigma is the sticky part that receives the pollen, the style is the tube that leads from the stigma to the ovary, and the ovary is the structure that contains the ovules.

11.Pollination is the process of:

(a) Transferring pollen from the male anther to the female stigma

(b) Fertilizing the egg cell in the ovule

(c) Developing the embryo into a seed

(d) Germination of the seed

Answer: (a)

Pollination is the process of transferring pollen from the male anther to the female stigma. This process is necessary for fertilization to occur.

12.Fertilization is the process of:

(a) Transferring pollen from the male anther to the female stigma

(b) Combining the male gamete with the female gamete to form a zygote

(c) Developing the embryo into a seed

(d) Germination of the seed

Answer: (b)

Fertilization is the process of combining the male gamete with the female gamete to form a zygote. This process is necessary for the development of a seed.

5.The process of seed germination involves:

(a) The absorption of water by the seed

(b) The growth of the embryo into a seedling

(c) The development of the root system

(d) All of the above

Answer: (d)

The process of seed germination involves the absorption of water by the seed, the growth of the embryo into a seedling, and the development of the root system. All of these processes are necessary for the seed to germinate and develop into a new plant.
