Answer 2

Answer:

In sexual reproduction, two parents are involved in producing a new individual. Offspring is produced by the fusion of gametes (sex cells) from each parent. Animals like dog, cats, lions, giraffe, humans, etc. all reproduce sexually.

Reproduction in plants takes place sexually and asexually as well. But the majority of the flowering plants reproduce sexually. The flower is the reproductive part of a plant i.e., both male and female gametes are produced by flowers. Sexual reproduction in plants takes place in flowers. The complete flower typically consists of four parts:

1. Petals
2. Sepals
3. Stamen (male reproductive part)
4. Pistil/Carpel (female reproductive part)
5. Stamen (male reproductive part) consists of anther and filament.

• The anther is a sac-like structure that produces and stores pollen.
• The filament supports the anther.
• The pistil (female reproductive part) comprises three parts- stigma, style, and ovary.
• Stigma is the topmost part of a flower.

The style is the long tube which connects the stigma to the ovary. The ovary contains a lot of ovules. It is the part of the plant where the seed formation takes place.

A flower may consist of either stamen or pistil or both. Based on this, a flower can be either unisexual or bisexual. A bisexual flower is composed of all the four parts mentioned above, e.g. Rose, China rose. Whereas, plants like papaya and cucumber produce only unisexual flowers.
