Test: Reproduction in Plants - Class 7 MCQ

Asexual reproduction involves the production of new individuals without the involvement of gametes or fertilization. It occurs in plants through vegetative reproduction.

Sexual reproduction involves the fusion of male and female gametes to produce offspring. It occurs in plants through the process of pollination and fertilization.

Asexual reproduction is the process by which new plants are produced from a single parent plant without the involvement of gametes. It occurs through vegetative reproduction.

Vegetative reproduction involves the production of new plants from vegetative structures such as bulbs, tubers, rhizomes, and corms.

Asexual reproduction produces genetically identical offspring because there is no exchange of genetic material between individuals.

Sexual reproduction in plants occurs through the production of seeds, which are the result of the fusion of male and female gametes.

Pollination is the process by which pollen is transferred from the male reproductive organ (anther) to the female reproductive organ (stigma) in plants.

Correct option is A. Bisexual flowers

Rhizomes are horizontal underground stems found in plants like grass and bamboo. They grow parallel to the ground and send out roots and shoots from their nodes.

Layering is a natural method of asexual reproduction in which a stem or branch is bent and buried in soil while still attached to the parent plant, and eventually develops roots and forms a new plant.

Asexual reproduction in plants involves the production of new individuals from vegetative parts such as roots, stems, and leaves.

Bulbs are underground stems that are swollen and store food for the plant. They have fleshy leaves called scales that surround a central bud.

Pollination is the process of transfer of pollen from the male reproductive part (anther) of a flower to the female reproductive part (stigma) of the same or another flower.

Fertilization is the fusion of male and female gametes (sperm and egg) to form a zygote, which develops into an embryo and eventually a new plant.

Sexual reproduction in plants involves the production of seeds through the fusion of male and female gametes.

The stem is not a part of a flower. Flowers have four main parts: sepals, petals, stamens, and pistils.

Germination is the process of seed sprouting and developing into a new plant under favorable conditions such as moisture, warmth, and oxygen.

Grafting is a method of vegetative propagation in which a stem or bud from one plant is joined onto another plant to grow as a single plant.

Runners are modified stems that grow horizontally above the ground or below the soil surface and produce new plants at their nodes.

Cross-pollination is the transfer of pollen from the anther of a flower to the stigma of another flower of the same species, which can result in greater genetic diversity.
