Through growth and development.
By growth we mean increase in size and also in the number of cells. An adult human, for example, has about 10 or even 100 trillion cells. The cell divisions are mitosis.
By development we mean that as the embryo grows cells become different, a process that is called, logically enough, differentiation. Cells not only become structurally different, but they acquire correspondingly different functions, too. So, to take a human again as an example, some cells are specialized for carrying oxygen around the body in the blood, some destroy bacteria that they encounter, others pump sugars out of the intestine into the blood after a meal, and so on. This division of labor makes for a highly complex and efficient organism.
So the first thing that visibly happens to a zygote is that it divides by mitosis into two cells, then they divide to form a four-celled embryo, and so on. Eventually the ball of identical-looking cells hollows and acquires an axis, and differentiation begins.
For more detail, see the links below.
During a process called fertilization, an egg is penetrated by a sperm cell, and the haploid genetic information of both male and female gametes combines. The result of this process is a diploid cell called a Zygote. A zygote cell receives half chromosomes from its female parent and half from it's male parent. The zygote then undergoes mitosis and cell division and developes into an Embryo.
the zygote forms by the union of a sperm and ova
yes, the zygote does become an embryo when it enters the womb. though insted of just floating in the womb it embeds itelf in the wall of the womb.
when egg is combine with sperm the process of fertilization take and zygote is formed this fertilization take place till 9 months after 9 months a new baby is born from this zygote.
zygote become a baby
i love u
when the ovary is fertilized the the fertilized egg will become a zygote
Embryo is produced by cell division of zygote .
Correct, the embryo develops in the womb, also known as the uterus.
it develops from a zygote.
After fertilization in sexual reproduction the zygote is formed. The zygote later on develops in to an embryo by embryo-genesis.
the word that represents a womens fertilised egg is zygote. hope this helps
The sperm unites with the Ovum in the womb, to form a zygote, which is the beginning of the Embryo.
One would think it's embryo but a zygote is not a embryo yet, it is the early stage of what will become a embryo. Zygote is the word used and you can use the word cell since a zygote is the initial cell formed after a sperm and egg have joined. After 1 week it has transformed into a embryo.
I dont freaking know
1. gametes - zygote - fertilization - embryo 2. fertilization - zygote - gametes - embryo 3. zygote - gametes - fertilization - embryo 4. gametes - fertilization - zygote - embryo answer is 4. gametes-fertilization-zygote-embryo
Babies don't become embryos, it's the other way around. A fertilised egg becomes a zygote, a zygote becomes an embryo, an embryo becomes a foetus, a foetus becomes a baby.
There really isn't much difference between a zygote, embryo, and fetus. A zygote forms after fertilization and becomes an embryo, which later becomes a fetus.
when the ovary is fertilized the the fertilized egg will become a zygote
8 weeks
Embryo is produced by cell division of zygote .
Correct, the embryo develops in the womb, also known as the uterus.
Yes. Sperm and eggs carry DNA - this combines to become the DNA of the zygote/embryo.
