The series of cellular divisions by which the zygote becomes a multicellular embryo is known as?
The series of cellular divisions by which the zygote becomes a multicellular embryo is known as cleavage. During cleavage, the zygote undergoes multiple rapid divisions without growth in between, leading to the formation of a blastula or blastocyst.
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.
What types of cell divisions are involved in creating a puppy?
The creation of a puppy involves mitotic cell division for growth and development, meiotic cell division for the formation of gametes (sperm and egg), and fertilization of the egg by the sperm to form a zygote that will develop into a puppy.
What does zygote contain?
A zygote is the result of the fusion of an egg cell and a sperm cell during fertilization. It contains all the genetic information necessary for the development of a new organism, including the DNA from both parents. The zygote will undergo multiple cell divisions to form an embryo.
The first mitotic division in the zygote occurs as soon as?
The first mitotic division in the zygote typically occurs within about 12-24 hours after fertilization. This division marks the beginning of embryonic development.
How many cells will there be after 8 successive mitotic divisions of a zygote?
After 8 successive mitotic divisions of a zygote, there will be 256 cells. Each mitotic division doubles the number of cells, so if the zygote starts with 1 cell, it will be divided into 2, then 4, then 8, and so on, until reaching 256 cells after 8 divisions.
Growth of the zygote and other stages of an animal's life happens by mitotic cell division?
Yes, the zygote undergoes multiple rounds of mitotic cell division to form a blastula, which then develops into a gastrula through additional cell divisions. During growth and development, cells continue to divide through mitosis to form tissues and organs. This process ensures that the organism grows and matures from a single cell to a complex multicellular organism.
How many cells will there be after 7 successive mitotic divisions of a zygote?
After 7 successive mitotic divisions, each cell will have undergone 8 rounds of division (the original division plus the 7 additional divisions). This means the number of cells will be 2^8, which is 256 cells.
How many cells will there be after 5 successive mitotic divisions of a zygote?
After 5 successive mitotic divisions of a zygote, there will be 32 cells. This is because each mitotic division doubles the number of cells, starting with the original zygote cell. So, it follows the pattern: 1, 2, 4, 8, 16, 32.
The series of cellular divisions by which the zygote becomes a multicellular embryo is known as?
The series of cellular divisions by which the zygote becomes a multicellular embryo is known as cleavage. During cleavage, the zygote undergoes multiple rapid divisions without growth in between, leading to the formation of a blastula or blastocyst.
In the alternation of generations life cycle two gametes fuse together to form a?
In the alternation of generations life cycle, two gametes fuse together to form a zygote. This zygote undergoes mitotic divisions to develop into a multicellular organism that will eventually produce gametes through the process of meiosis.
What only takes place in the reproductive tissues of an organism and during it a single cell goes through two cell divisions?
Zygote

Does a zygote undergo mitosis during the development of the embryo?
Yes, a zygote undergoes mitosis during the development of the embryo. After fertilization, the zygote divides through a series of mitotic divisions, leading to the formation of a multicellular structure known as a blastocyst. This process of cell division is essential for the growth and development of the embryo as it establishes the foundation for further differentiation and organ development.
The first mitotic division in the zygote occurs as soon as?
The first mitotic division in the zygote typically occurs within about 12-24 hours after fertilization. This division marks the beginning of embryonic development.
