Metaphase (from Ancient Greek μετα- ( meta-) beyond, above, transcending and from Ancient Greek φάσις (phásis) 'appearance') is a stage of mitosis in the eukaryotic cell cycle in which chromosomes are at their second-most condensed and coiled stage (they are at their most condensed in anaphase ). [ 1] These chromosomes, carrying ...
Mitosis in the animal cell cycle (phases ordered counter-clockwise). Mitosis divides the chromosomes in a cell nucleus. Onion cells in different phases of the cell cycle enlarged 800 diameters. Mitosis ( / maɪˈtoʊsɪs /) is a part of the cell cycle in which replicated chromosomes are separated into two new nuclei.
Alternation of generations (also known as metagenesis or heterogenesis) [ 1] is the predominant type of life cycle in plants and algae. In plants both phases are multicellular: the haploid sexual phase – the gametophyte – alternates with a diploid asexual phase – the sporophyte . A mature sporophyte produces haploid spores by meiosis, a ...

Vegetative reproduction. Production of new individuals along a leaf margin of the air plant, Kalanchoe pinnata. The small plant in front is about 1 cm tall. The concept of "individual" is stretched by this process. Kalanchoe daigremontiana produces plantlets along the margins of its leaves. When they are mature enough, they drop off and root in ...
The mitotic index is a measure of cellular proliferation. [ 1] It is defined as the percentage of cells undergoing mitosis in a given population of cells. Mitosis is the division of somatic cells into two daughter cells. Durations of the cell cycle and mitosis vary in different cell types. An elevated mitotic index indicates more cells are ...
Plant reproduction is the production of new offspring in plants, which can be accomplished by sexual or asexual reproduction. Sexual reproduction produces offspring by the fusion of gametes, resulting in offspring genetically different from either parent. Asexual reproduction produces new individuals without the fusion of gametes, resulting in ...
