What is a zygote and what is its function?

Question

What is a zygote and what is its function?

Answer 1

A fertilized egg. A diploid cell resulting from fertilization of an egg by a sperm cell.The zygote contains all of the genetic information (DNA) necessary to become a child. Half of the genetic information comes from the mother’s egg and half from the father’s sperm. The zygote spends the next few days traveling down the Fallopian tube and divides to form a ball of cells.

Answer 2

A fertilised egg.

Uhm.. To maka da baby.  

Answer 3

A zygote (from Greek zygotes ‘joined’, from zugoun ‘to join’) is a cell that is the result of fertilization. That is, two haploid cells—usually an ovum from a female and a sperm cell from a male—merge into a single diploid cell called the zygote (or zygocyte).

In mammals, fusion of the sperm with the ovacyte occurs in the fallopian tube and the resulting diploid zygote becomes embedded in the uterine wall.

Animal zygotes undergo mitotic cell divisions to become an embryo. Other organisms may undergo meiotic cell division at this time (for more information refer to biological life cycles).

Answer 4

A zygote is an egg that has just been fertilized

Answer 5

A zygote (from Greek zugōtos ‘joined’, from zugoun ‘to join’) is a cell that is the result of fertilization. That is, two haploid cells—usually an ovum from a female and a sperm cell from a male—merge into a single diploid cell called the zygote (or zygocyte).

In mammals, fusion of the sperm with the ovacyte occurs in the fallopian tube and the resulting diploid zygote becomes embedded in the uterine wall.

Animal zygotes undergo mitotic cell divisions to become an embryo. Other organisms may undergo meiotic cell division at this time (for more information refer to biological life cycles).

A one-celled zygote - the product of fertilization - become a multicellular organisms with tissues, organs, and other specialized cells and structures.

Most animals, including humans, go through 6 stages of embryonic development: Successful development at each stage depends on successful completion of the stage before!

1. Gamete formation (n + n): eggs and sperm are produced in specialized tissues (We already discussed Meiosis!)

2. Fertilization: the union of egg and sperm

-Occurs in Fallopian Tubes (usually)

- 200 million sperm to one egg! (sometimes 2, 3 or more eggs!).

-When 1 sperm penetrates the zona pellucida (clear zone around egg), cortical granules are released that prevent any other sperm from penetrating the egg

- After fertilization, the egg and sperm and nuclei fuse, and a new diploid human zygote results (2n) - the first cell of the new animal...



The Moment of Fertilization  

3. Cleavage: The first days and weeks after conception: mitotic cell divisions begin, converting the zygote to a multicellular organism

Day 1: first cleavage - 1 cell becomes 2

Day 2: second cleavage - 4-cell stage

Day 3: 6-12 cell stage - can test at this stage for genetic diseases if done by IVF

Day 4: 16-32 cell stage - solid ball of cells - morula

Answer 6

A fertilized omelete

Answer 7

a zygote is a is a cell that is the result of fertilization.it is formed when ovum from female,sperm from male fuse together.

hope it helps you
