buddinglisääntymistä

Buddinglisääntymistä, commonly known as budding, is a form of asexual reproduction where a new organism develops from an outgrowth or bud due to cell division at one particular site. The bud remains attached to the parent organism and eventually detaches to live independently. This process is observed in various organisms, most notably in yeast and some simple multicellular animals like Hydra.

During budding, the parent cell or organism undergoes mitosis, resulting in an unequal distribution of cytoplasm. A small, new cell or outgrowth, the bud, forms on the parent. This bud grows and develops its own specialized structures. Once the bud has matured and is capable of independent survival, it separates from the parent. The parent organism's genetic material is passed on to the bud, meaning the offspring is genetically identical to the parent.

Budding is an efficient method of reproduction when environmental conditions are favorable, as it allows for rapid population growth without the need for a mate. It bypasses the complexities of meiosis and fertilization. While common in single-celled organisms, budding is also seen in some invertebrates such as corals and sponges, where it contributes to colony formation and asexual propagation. The detached bud then grows into a new, independent individual.
