There is no growth because during cleavage the cells skip the G1 and G2 stages of interphase (when cell growth usually occurs). Because of this, cytoplasm volume stays constant throughout cleavage, only there are more cells to comprise the same volume.

Early rapid cell division without growth?
cleavage
What is a rapid cell division with the absence of growth between divisions?
Cleavage
What point in mitosis does a cleavage furrow form?
During cytokinesis in mitosis a cleavage furrow forms.
What stage does the cleavage appear in mitosis?
There are five stages of mitosis starting with prophase and ending with telophase. The cleavage furrow develops during cytokinesis which is after the telophase, so the cleavage furrow does not develop in mitosis at all.
How is cleavage different from mitosis?
Cleavage is the creation of new cells with no cell growth. The cytoplasm gets split up within the same cell, so you don't actually create an entirely new cell, but a division on the larger cell. Mitosis results from cell growth and creates entirely new cells.
What is a blastomere?
A blastomere is any cell which results from division of a fertilized egg.
Early rapid cell division without growth?
cleavage
How does cleavage reduce the size of cells in an embryo?
During cleavage G1 and G2 stages are by-passed so cells simply progress from S (DNA synthesis) to M (mitosis) without the intervening growth phaseAs a result cleavage cells continue to decrease in sizeuntil they approximate the size of normal somatic cells
What are the satges of growth and development?
the stages of growth are: gametogenesis fertilization cleavage or segmentation blastulation gastrulation organogenesis

At what point in mitosis does cleavage furrow form?
During cytokinesis in mitosis a cleavage furrow forms.
At what point in mitosis does a cleavage furrow form?
During cytokinesis in mitosis a cleavage furrow forms.
What point in mitosis does a cleavage furrow form?
During cytokinesis in mitosis a cleavage furrow forms.
What are the Physiological differences of cleavage between mammals and birds?
What kind of cleavage are you referring to? Cleavage could refer to a cleavage furrow during cytokinesis or to the splitting of cells in an embryo or to any other sort of separation. Please specify.
Is the sea star embryo growing during cleavage?
no.
Which of these shows the correct sequence of development of sexually reproducing animals?
fertilization, cleavage, differentiation,growth
Are nearly identical cells that are produced by early cleavages?
blastomere
