Blastula

... The blastula is an early stage of embryonic development in animals . It is produced by cleavage of a fertilized ovum and consisting of a spherical layer of cells surrounding a fluid-filled cavity. The blastula follows the morula and precedes ...

Meiosis

... disappearance of the chromosomes occur as well as the disappearance of the fibres and the replication of the centrioles. Nuclear envelopes reform; cleavage or cell wall formation eventually produces a total of four daughter cells, each with an haploid set of chromosomes. Significance of meiosis If ...

Mitosis

... membrane reforms around the genetic material and the chromosomes are unfolded back into chromatin. This is often followed by cytokinesis or cleavage , where the cellular membrane pinches off between the two newly separated nuclei, to form two new daughter cells. At this point, each new nucleus ...

Morula

... of embryonic development in animals , including the 16-cell phase, the 32-cell phase, and the 64-cell phase. The morula is produced by embryonic cleavage , the rapid cell division of the zygote with virtually no growth. The morula is a solid ball; after the 64-cell phase, it develops into a hollow ...
