Based on the mode of producing offspring, asexual reproduction is classified into several types, viz.: A. Fission Fission simply means division. It is a mode of asexual reproduction where unicellular organisms divide into two or more individuals. It is the…
Asexual reproduction is the type of reproduction where offspring are produced without the fusion of male and female gametes. It is a reproduction process where only one individual makes its progeny without exchanging genetic material with another individual. Generally, it…
Reproduction is a biological process of producing offspring of a living organism. It is the basis for continuing life from generation to generation. It is seen in every living organism; from microorganisms to larger organisms including all plants and animals.…
Almost all animals have the capacity to reproduce sexually. Only a few animals, mainly lower invertebrates and a few vertebrates, reproduce asexually together with the asexual mode. Most multicellular animals show exogamy with anisogamous gametes. Most the unicellular animals follow…
All the flowering plants have the capacity to sexually reproduce. A flower is the reproductive organ of plants that produce gametes. The androecium is the male reproductive part which contains the stamen where sperm is produced, while the gynoecium is…
Broadly, sexual reproduction can be classified into two types; conjugation and syngamy. 1. Conjugation It is a type of sexual reproduction process where two individuals temporarily fuse and exchange their genetic materials through the pronuclei. It is seen in certain…
The sexual reproduction process can be divided into three basic stages, viz.: 1. Gametogenesis (Pre-fertilization stage) This stage involves the formation of gametes (gametogenesis) and the transfer of the gametes. Mature male parents produce male gametes (sperms) in male gonads…
