Meiosis has the same four steps as mitosis (prophase, metaphase, anaphaseandtelophase) but includes two successive divisions that result in four daughter cells instead of two, each with 23 chromosomes instead of 46. This is enabled by the markedly different mechanics ofmeiosis 1andmeiosis 2. The...

One of the most important processes for all living organisms is mitosis. In this lesson, explore the meaning, stages, and purpose behind this biological process. What is Mitosis? Ever wonder how the human body grows from a tiny baby into an adult? Or how a scrape on our knee can disappea...
mononuclear and binuclear sporangial initials can be seen.2: Sporangial initial divided into outer tapetum cells and inner spore mother cells.3: The spore mother cells undergo the first meiosis.4: The two cells changed from mononuclear to binuclear.5: The two-cell binucleate divided into four...
Meiosis, division of a germ cell involving two fissions of the nucleus and giving rise to four gametes, or sex cells, each with half the number of chromosomes of the original cell. The process of meiosis is characteristic of organisms that reproduce sexu
The process of meiosis is characteristic of organisms that reproduce sexually. Such species have in the nucleus of each cell adiploid(double) set of chromosomes, consisting of twohaploidsets (one inherited from each parent). These haploid sets are homologous—i.e., they contain the same kinds ...
