Most plants reproduce sexually, primarily through seeds formed in flowers. This process involves the reproductive organs: the stamen (male) and the pistil (female). The stamen produces pollen grains, while the pistil, containing the ovary, style, and stigma, houses the egg cell. Successful seed production requires pollination, where pollen from the stamen reaches the stigma. This can occur via self-pollination or cross-pollination, facilitated by wind or animals like insects. Following fertilization, ovules develop into seeds, with the surrounding ovary transforming into fruit, completing the life cycle.

How Plants Grow and Multiply
Sexual Reproduction Most plants grow from seeds
These plants have parts that making of seeds. These seed-making of plants are found in the flower.
Sexual Reproduction The pistil and the stamenare parts of the flower that are responsible in the making of seeds in flowering plants
Stamen Is the male reproductive organ. It consist of stalk called the filament and an ovoid structure at its tip called the anther. The anther bear the pollen grains.
Pistil The pistil is the female reproductive organ found at the center of the flower. It consist of the ovary ,style, and the stigma. An egg cell is formed in the ovule. The ovules, after fertilization, will develops into seed and the ovary surrounding it becomes the fruit of most plants.
One of the important function of the flower is to produce seeds. How? Pollination
If seeds are to be produced, the pollen grains from the anther must land on the stigma. This transfer of pollen grains to the stigma is called Pollination
Pollination Pollination occur mainly by wind and by animals such as insects and birds. Pollination
Pollination Self pollination When pollen from a plant’s anther is transferred to that same plant’s stigma, it is called self pollination.
Pollination Crosspollination When pollen from a plant’s anther is transferred to another plant’s stigma it is called cross pollination.
What is fertilization? How does fertilization in flowers lead to the formation of seeds?
