unicellular sexual reproduction

In unicellular organisms the cell leads a totally independent life. It does not depend on any other cell for any of its activity, except in cases of sexual reproduction. There is division of labour only at the organelle level since different organelles perform specific..

Sexual Reproduction in Animals - Sexual reproduction is seen in nearly all animals. In animals reproduction also involves production of gametes that are haploid cells . In unicellular organisms like the protozoans, the gamete-producing ind..

Sexual Reproduction - 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 protozoa..

In bacterial sexual reproduction there is no meiosis, formation of gametes and zygote. Instead, it involves transfer of a portion of genetic material (DNA) from a donor cell to a recipient cell. This process is called as genetic recombination or parasexuality . It is known to oc..

Sexual reproduction is known to occur in all groups of fungi except the Fungi imperfecti or Dueteromycetes . It may involve fusion of gametes, gametangia or hyphae. The process may involve only fusion of cytoplasm ( plasmogamy ) or fusion of nuclei ( karyogamy ) or production of..

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 are p..

Sexual Reproduction - Sexual reproduction involves the formation and fusion of special sex cells called gametes. It is a complex proce..
