sexual and asexual reproduction in planaria

Binary Fission - It is the most common mode of asexual reproduction. The cytoplasm and nucleoid of a bacterial cell divide equally into two, following replication of DNA. The cell wall and cytoplasm also split resulting in the formation of two daughter cells. Under favourable co..

The human beings are bisexual with two separate sexes - male and female. The individuals of the two sexes show distinctive features called the secondary sexual characteristics. Some of the male secondary sexual characteristics are facial hair, cracking of voice, etc. femal..

Accumulation of Variation During Reproduction - All round us we see different organisms from the lowest forms to the highest. Species differ from each other. However, the variation we focus relates to the differences among individuals of a species. No two individuals are identical to each..

Human Reproductive System - In human beings, sexual reproduction takes place. Sexes are separate and hence they are known to exhibit sexual dimporphism. Males have sex organs called the tetes while the females have sex organs called the ovaries. Even in the e..

>Mitosis occurs in all the living cells of the body of an organism. Hence it is called somatic cell division. Mitosis is described as equational division since the chromosome number of daughter cells will be same as that of the parent cell. Mitosis has an interphase, karyokinesis and cytokinesis. I..

Regeneration is one of the methods of asexual reproduction in lower or less evolved animals. When the parent body breaks into pieces, each piece can grow into a new organism. ..

Reproduction occurs by vegetative propagation, asexual and sexual reproduction. Vegetative propagation through artificial method can be done by cuttings, layering and graftin..

Cell Division - Cell division forms a mode of reproduction in unicellular organisms. In multicellular organisms it is responsible for embryonic development and growth of the adult organism. It is also involved in repair and regeneration. Both asexual and sexual re..
