Question

Does meiosis occur in plants?

Answer 1

Meiosis is a special type of cell division of germ cells in sexually reproducing organisms used to produce gametes, such as sperm or egg cells. It is called "lessening" because it is a reductional division. It takes two rounds of division to produce four cells, each with only one copy of each chromosome (haploid).

Complete answer:
Meiosis is a process that happens in all animals and plants. Although the ultimate outcome, gametes with half the number of chromosomes as the parent cell, is the same, the detailed procedure is not. Meiosis creates gametes directly in mammals.

Between meiosis and the formation of sperm and eggs in plants, there is a brief pause. During this time, a separate haploid plant emerges. Mitosis is the process by which gametophytes create gametes. Meiosis creates sperm and eggs in animals, but it produces the gametophyte in plants.

Megaspore mother cells (megasporocytes) within the ovules of ovaries and microspore mother cells (microsporocytes) within the anthers of stamens undergo meiosis in flowering plants.

In plant breeding, meiosis is critical because it allows breeders to produce new allele combinations. Controlling this process, particularly in terms of crossing over creation and dispersion, can have a significant impact on the breeding effort's outcome. Elite F1 hybrids are created from selected parents in traditional breeding.

Note: Plants go through mitosis in their meristems, which are found at the tips of their stems and roots. These two areas are in charge of producing all of the cells that the plants require to grow. Meiosis' goal is to create gametes, such as sperm and eggs, that have half of the genetic complement of the parent cells.
