Asexual reproduction in animals and plants

Types of reproduction in animals and plants

In the course of the last millions of years the animal and plant world has developed ingenious methods for Reproduction developed. There are many differences between the reproduction of plants and animals, but also some similarities. In the following, asexual reproduction in animals and plants is described in more detail, as well as examples of the asexual Multiplication in the animal and plant kingdom entered.

Asexual reproduction in animals and plants

Asexual reproduction is also called asexual or vegetative Called multiplication. Asexual means to reproduce no Germ cells (as in sexual reproduction) are needed. How can this work? In asexual reproduction, the offspring emerge from body cells or spores (persistence stages). By mitotic division emerges a hereditary individual, a clone of the parent organism. This means that the genetic makeup of an organism is copied and created genetically identical offspring.

But how do protozoa and spores multiply? ? The organisms can reproduce asexually in various ways. Bacteria and some protozoa cause one Dichotomy through, other protozoa, fungi and also plants can also through Multiple division multiply.

Asexual reproduction occurs in the animal kingdom only in lower organisms, for example in Worms. For example, they have a special position Cnidarians: You plant your way through Budding away. During budding, cell complexes develop on the surface of the mother individual, which are then pinched off. The constricted complexes either remain on the mother organism and form Colonies, or develop into mobile Individuals.

During the vegetative reproduction of the plants, new individuals can emerge from a part of the Body of vegetation form. The vegetation body includes the parts of the plant that do not serve sexual reproduction, for example root, Stem axis or leaf. You probably already know that from one of our staple foods: the potato. Farmers plant the Tubers into the ground to keep them multiplying.

advantages of asexual reproduction are rapid reproduction and independence from a sexual partner. However, due to the vegetative type of reproduction, adaptations to changing living conditions can only develop very slowly.
