What is formed when an sperm fertilizes an egg?
Zygote
What major process leads to the zygote's transformation into an embryo?
Cleavage - the repeated cell division of the zygote to create a blastula.Gastrulation - the formation of distinct layers which later give rise to different structures.
What is cleavage in anatomy?
Cleavage is a mineral's tendency to break along flat, parallel surfaces (cleavage planes). Excellent cleavage direction reflects light in one direction, it is considered basal, or book cleavage. Biotite and muscovite have excellent cleavage. Good cleavage reflects light in one direction from a set of many small flat surfaces, augite and gypsum are examples. Poor cleavage directions reflect light form surfaces that are hard to detect, and this is true for sulfur.
What process of rapid mitotic cell division without intervening growth periods?
This process if known as cleavage. The cells divide rapidly, but there is no overall increase in the size of the zygote.
Does the zygote results from the union of the sperm and egg cell?
The zygote is the first cellular form of development in mammals. This results from the union of the sperm and egg cell.
What is the correct sequence of development from zygote to embryo?
cleavage, morula, blastocyst, gastrula
What is a determinate cleavage?
Determinate cleavage is the cleavage of an egg that separates portions of the zygote for development. Cleavage is a form of cell division that increases cells without increasing mass.
What process occurs immediately after a zygote form?
CLEAVAGE The cleavage process directly follows the zygote stage. The zygote stage is the earliest developmental stage of an embryo.
The series of cellular divisions by which the zygote becomes a multicellular embryo is known as?
The answer is Cleavage because Cleavage is the first mitotic divisions of the zygote. There is an increase in the number of cells but a decrease in size of the individual cells.
As soon as the zygote begins growing and dividing it is called what?
embryo
What is one development process involved in changing from a zygote to an embryo?
Meiosis or Mitosis either one.
What is the correct order of developmental sequence - Fertilization blastula gastrula adult zygote cleavage embryo meosis?
In order: meiosis in parents (creates gametes), fertilization, zygote, cleavage, blastula, gastrula, adult (obviously after baby is formed and born).
Describe the principal events occurring during the cleavage stages of the embryo?
Cleavage is a series of cell divisions that subdivided the cytoplasm of the zygote.
What does embryo mean?
After cleavage a zygote forms embryo until it is born or hatched .
What is formed when an sperm fertilizes an egg?
Zygote
Successive cell divisions convert the zygote into a multicell embryo during?
Type your answer here..cleavage
According to human reproductive system what is the meaning of cleavage?
While still in the Fallopian tube, the zygote begins to endergo mitosis. It divides repeatedly through a process called cleavage.
