The finding that transition from mitosis to meiosis may occur in cultured plant cells, and therefore possibly an alternative pathway of the mitotic process under stressing conditions, may offer a possible solution for the totipotency enigma. These data and the unexpected finding that plants ...
In this viewpoint, the usages of terms for progenitor cells to meiosis and gametogenesis are discussed. Terms for 2 types of germ cells, i.e. "diploid germ cells" and "haploid germ cells" were suggested to replace "archesporial cells" and "generative cells," respectively, in plant ...
Eukaryotic cells are more complex and have different strands of DNA in an enclosed area called a nucleus. What are the three types of cell division? The three types of cell division are binary fission, mitosis, and meiosis. Binary fission occurs in prokaryotic cells, mitosis creates genetically...
and have long, tail-like projections calledflagella. Female sex cells or ova are non-motile and relatively large in comparison to male gametes. Insexual reproduction, sex cells unite duringfertilizationto form a new individual. While other body cells replicate bymitosis, gametes reproduce bymeiosis....
In animals, sexual reproduction comprises the fusion of two distinctgametesto form adiploidzygote. Gametes, which arehaploidare produced by cell division calledmeiosis. In most cases, a male gamete (spermatozoan) is relatively motile and usually has aflagellumto propel itself. A female gamete (ovu...
All somatic cells divide by mitosis to maintain their chromosome number; hence, they never divide by meiosis. Only germline cells undergo meiotic cell division. The word 'somatic' originates from the Greek word "soma", which refers to somatic cells' presence in all locations of the body....
Cells are the basic, fundamental unit of life. So, if we were to break apart an organism to the cellular level, the smallest independent component that we would find would be the cell. Explore the cell notes to know what is a cell, cell definition, cell structure, types and functions of...
The somatic cells of several protists, algae and fungi have haploid number of chromosomes. Doubling of chromosomes occurs in the zygote but meiosis occurs in it to restore haploid condition. Male Honey Bee is also haploid because it develops parthenogenetically from an unfertilized egg. ...
