Some plants reproduce themselves from leaves. One example of a plant which can reproduce from its leaves is “bryophyllum”. When a mature leaf of the “bryophyllum” plant falls on the ground, they grow into a new plant.

Asexual reproduction takes place through budding in:

Budding is an asexual method of reproduction. In budding, a small part of the body of the parent plant grows out as a bulb-like projection called “bud” which then detached and becomes a new plant. Yeast is a single celled plant which reproduce by budding.

Here, all the statements are correct. Hence, your answer will be option [D].

Recently, in a science class test, you are asked a question where you have to say whether the statements are correct or not?

The roots of some plants like sweet potato and Dahlia can be used to produce new plants. And also, leaves of some plants can reproduces new plants, such as Bryophyllum.

Which of the following parts of a plant take part in sexual reproduction?

The flowers perform the function of sexual reproduction in plant. After fertilization, the ovary grows into a fruit and seeds develop from the ovules.

In a science quiz competition, Nidhi are asked a question where she had to choose the statement which was/were incorrect?

An alga, spirogyra reproduce by the asexual method of reproduction called fragmentation. But yeast reproduces by budding.

Which of the following statements are true for flowers?

The process in which the male gamete present in pollen grain fuses or joins with the female gamete present in ovule to form a new cell called zygote, is called fertilization. After fertilization two main things happen. As the ovule present in ovary grows to become a seed. After fertilization ovary of a flower develops and becomes a fruit (with seeds inside it). Thus, fruit is the ripened ovary of a flower.

Lila observed that a pond with clear water covered up with green algae within a week. By which method of reproduction did the algae spread so rapidly?

In the presence of water and nutrients, algae grow and multiply rapidly by fragmentation. An alga breaks up into two or more fragments, each of which grow into new individuals. This process covers a large area in a short period of time.

The reproductive part of a plant is the

Most plants have roots, stems and leaves. These are called the vegetative parts of a plant. After a certain period of growth, most plants bear flowers. The flowers perform the function of reproduction in plants. Flowers are the reproductive parts of a plant.

Which of the following does not reproduce by the asexual method of spore formation?

Spore formation is an asexual method of reproduction in plants, spores are not seeds. Most of the fungi and flowerless plant (such as “ferns and mosses”) reproduce asexually by means of spores. The common “bread mould” plant which grows on a piece of stale bread is a fungus. The common bread mould plant on rhizopus fungus reproduces by the method of spore formation. An alga, reproduces by the asexual method of fragmentation.

In the last year board examination, Arun were asked a question where he had to choose the statement which was/were incorrect? Will you be able to answer this question?

Here, all the statements are correct. Hence, your answer will be option [D].

The “eye” of the potato plant is what:

The eye of the potato is the same as the bud is to “Bryophyllum” leaf. Both the structures are vegetative propagules. They can form a new plant from them. This method of asexual reproduction through the vegetative parts of the existing plant is called “vegetative propagation”.

The process of fusion of the male and female gametes is called:

The process in which the male gamete present in pollen grain fuses or joins with the female gamete present in ovule to form a new cell called zygote, is called fertilization. After fertilization two main things happen. As the ovule present in ovary grows to become a seed. After fertilization ovary of a flower develops and becomes a fruit (with seeds inside it). Thus, fruit is the ripened ovary of a flower.

Which of the following reproduces by the process of fragmentation?

The breaking up of the body of a plant into two or more pieces on maturing, each of which subsequently grows to form a new plant, is called fragmentation. Spirogyra is a green filamentous alga plant which is found in ponds, lakes and slow-moving streams. Spirogyra reproduces by the asexual method of reproduction called fragmentation.

One of the following is not reproduce by the cutting method. This one is:

Cutting are a means of asexual reproduction in plants. The new plant formed from a cutting is exactly similar to the parent plants. The plants like rose, money plant, grapes, sugar cane, bananas, cactus can be grown by cutting method or by using stem cutting or branch cutting. But maize or corn is a plant belonging to the family of grasses. It does not flower readily and seed production is unusual except in its native habitat. Under natural conditions, maize reproduces only by seed production.

Which of the following event in the reproduction in flowering plants can be carried out by a butterfly?

For the male gamete to be able to combine with the female gamete, it is necessary that first the pollen grains from the anther of stamen of a flower should be carried to the stigma of pistil. The transfer of pollen grains from the anther of a stamen to the stigma of pistil is called pollination. When pollination is done by insects such as bees and butterflies, called cross-pollination.

The ovaries of different flowers may contain:

Ovary is the part of female reproductive organ of the plant. It may contain one or many of ovules in different flowers. The ovule in turn contains the female gametes of egg.

The seeds or fruits of which of the following plant are not dispersed by wind?

The seeds and fruits dispersed by wind either have wing like structures or they have hair or they are very small and light, which helps them to be easily carried away by the blowing wind. Such as the seed of drumstick plant, the seeds of madar plant, the plants like grasses and orchids have very small and light seeds which can be easily blown away by the wind for dispersal. The seeds of water lily plant and coconut plant are dispersed by water.

Pollination refers to the:

The transfer of pollen grains from anther of a stamen to stigma of a pistil is called pollination. It can occur by two ways as self-pollination (transfer occur in same flower or another flower of same plant) and cross-pollination (transfer occurring between flowers of two separate but similar plants. Insects, water and wind are agents of pollination.
