Question

The male reproductive organs in plants are
A) Sepals
B) Stamens
C) Petals
D) Carpel

Answer 1

Hint: The reproductive organs of plants involve the flower. The flower carries the pollen grains. Stamen, ovary, etc. are the parts of flowers that are involved during sexual reproduction.

Complete answer:
To solve the question, we should first understand about the sexual reproduction in plants. The sexual reproduction in plants takes place through pollination and is divided into self-pollination and cross pollination. The pollination process takes place in flower; the flower part consists of sepals which are the green leaf-like parts of the flower. It involves the protection of flowers when it is in bud form. Petals are the coloured part of the flower that attracts the pollinators towards itself. Stamen is found inside the petals made of filaments and anther. The anther produces pollen grains that carry the male gametes. Therefore the stamens are the male reproductive part. Carpel is found in the centre of the plant that is in flask shape. It is divided into stigma, style, and ovary. The pollen grains from the stigma fall on the carpel, and from the style tube it reaches to the ovary for fertilization of the egg for reproduction.

Now lets us find the solution from the given options:
Sepals is the part of the flower that supports the flower during its bud phase, it is the green part of the flower. This part does not involve the reproduction process.
Stamen is the male reproductive part of the plant that is found inside the petal ring. It consists of filaments and another. The anthers carry the male gametes that fall on the carpel that is the female reproductive part.
Next, petal is the coloured part of the plant that involves the attraction of the pollinators. The petals have different odours in different plants.
The carpel is the female reproductive part of the plants. It is found in the centre of the flowers that consists of stigma, style, and ovary. The pollen grains fall on stigma and through the style tube reach to the ovary there the fertilization takes place.

Thus, the right answer is option B. i.e., Stamens.

Note: The pollen grain that falls on the stigma gets bursts open and through the pollen tube that is style the pollen enters to the ovule; the pollen carries the male gametes. The male gametes get fused with the nucleus of the female gametes and the egg gets fertilized to form zygote.
