What is cleavage used for?
In embryology, cleavage is the process of cell division in the early stages of development that leads to the formation of a multicellular organism. It separates the zygote into multiple cells, ensuring proliferation and differentiation of cells for proper development.
What does the union of the gametes during fertilization leads to the production?
The union of gametes during fertilization leads to the production of a zygote, which is a single cell with a full set of chromosomes. This zygote then undergoes several rounds of cell division through the process of mitosis to develop into a multicellular organism.
How does a single undifferentiated cell lead to a complex multicellular organsim?
The process that leads a single undifferentiated egg cell to develop into a complex organism is not fully understood. This process of differentiation is an area of active research. It is known that the key lies in methods of gene expression.
Difference between cleavage and mitotic cell division?
Cleavage is a series of rapid cell divisions in the early embryo that leads to the formation of a multicellular organism, without an increase in overall size of the individual cells. Mitotic cell division is a process in which a single cell divides to produce two identical daughter cells, allowing for growth, repair, or maintenance of tissues in multicellular organisms.
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 process allows a single celled zygote to develop into a multicellular organism?
The process is called embryogenesis, which involves cell division and differentiation. During embryogenesis, the zygote undergoes multiple rounds of cell division to form a ball of cells called a blastocyst, which then develops into specialized cell types and tissues through a process called morphogenesis. This leads to the formation of different organs and structures in the developing organism.

What process of cell division occurs after fertilization?
After fertilization, the zygote undergoes mitotic cell divisions to form a multicellular organism. This process, known as cleavage, involves rapid cell divisions without growth, resulting in a cluster of smaller cells called blastomeres. Cleavage ultimately leads to the formation of a blastula or blastocyst.

How is cell division responsible for growth?
Cell division is responsible for growth because the new cells replace the dead cells in an organism. The new cells keep the organism alive by continuing to the job of the cell that it divided from.
How are cleavage and embryo different in meaning?
Cleavage is the division or split Another definition is the portion showing between a woman's breasts that is often supported by a bra. An embryo is a human that is still forming inside the uterus of a woman.
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 type of cell division occurs in cloning?
Cloning typically involves somatic cell nuclear transfer, where the nucleus of a somatic cell is transferred into an enucleated egg cell. This process leads to the creation of a genetically identical organism to the original donor.
What is a fertilized egg cell called when it divides?
It is called a morula, and consists of the first 16 cells from the division of the zygote (fertilized egg). The individual undifferentiated cells are known as blastomeres, and form a hollow structure called a blastocyst. Once differentiation of cells occurs, the structure is simply called an embryo, and later a fetus.
Division of labor results in?
The division of labor generally leads to specialization in any production line. Furthermore, division of labor increases the efficiency of production and makes the process faster.
