Science 4 - Pollination

Explanation
Pollination is the process by which pollen is transferred in plants. It is essential for plant reproduction as it allows for the transfer of male gametes (pollen grains) from the stamen (male reproductive organ) to the stigma (part of the female reproductive organ). This transfer can occur through various means, such as wind, water, or by the help of animals like bees, butterflies, or birds. Pollination plays a crucial role in fertilization and the production of seeds and fruits in plants.

Explanation
The male part of a flower is called the stamen. It is responsible for producing and releasing pollen, which is necessary for the fertilization of the flower. The stamen consists of two main parts, the filament and the anther. The filament is a long, thin structure that supports the anther, where the pollen is produced. The stamen plays a crucial role in the reproductive process of flowering plants by producing and dispersing pollen.

Explanation
The female part of a flower is the pistil. It is the reproductive organ that typically consists of three parts: the stigma, the style, and the ovary. The stigma is the receptive surface for pollen, and the ovary contains the ovules, which develop into seeds after fertilization.

Explanation
Stamen is the male reproductive organ of a flower, which produces pollen. Pollen is a fine, powdery substance that contains the male gametes of a plant. It is usually sticky in nature and is responsible for fertilizing the female reproductive organs of the flower. Therefore, the correct answer is pollen.

Explanation
The top of the pistil is called the stigma. The stigma is a sticky surface that receives pollen during pollination. It plays a crucial role in the reproduction of flowering plants by capturing and holding onto pollen grains, allowing for fertilization to occur.
