sexual and asexual reproduction in planaria

Sexual reproduction mostly occurs in higher multicellular plants and animals. However, it is also seen in lower organisms like the bacteria, Spirogyra (an alga) and Paramoecium (a protozoan..

In flowering plants, flowers have taken the place of conventional sex organs, and the ovules which later on develop into seeds are enclosed within an ovary. The sexual reproduction in angiosperms involves the fusion of two gametes, the male and the female. The male gametes..

Cyanobacteria reproduce mostly by vegetative and asexual methods. Vegetative reproduction occurs by fission or fragmentation or by the formation of hormogonia. Unicellular forms exhibit fission while filamentous multicellular forms exhibit fragmentation. Asexual r..

Definition - Production of offsprings by a single parent without the formation of gametes is called asexual reproduction. It is also called as somatogenic reproduction..

There is no need for sexual partners. No chance for combinations, so no variation in the populatio..

Types of Asexual Reproduction - The principal forms of asexual reproduction are Binary fission Multiple fission Budding Fragmentati..

Regeneration of new plants from the vegetative parts of the parent plant is called vegetative propagation or vegetative reproduction. Vegetative propagation is done with the help of vegetative parts such as roots, stem or leaves. These parts may also be variously modified for vegeta..
