Reproductive functions refer to the biological processes that enable organisms to produce offspring. In animals, this includes the production of gametes, such as sperm and eggs, through a process called meiosis. These gametes combine during fertilization to form a zygote, which develops into a new individual. In plants, reproductive functions involve the formation of flowers, which contain reproductive organs. Pollination occurs when pollen from the male part of the flower, called the stamen, reaches the female part, known as the pistil. This leads to fertilization and the development of seeds, ensuring the continuation of the plant species.
