The exchange of substances between mother and embryo takes place where?
The exchange of substances between the mother and embryo takes place in the placenta. The placenta is a temporary organ that develops during pregnancy to provide nutrients and oxygen to the embryo and remove waste products. This exchange is crucial for the growth and development of the embryo.
What type of cell division takes place in the ganads?
Meiotic cell division takes place in the gonads in order to produce sex cells.
What is special about the cell division that takes place soon after an egg cell is fertilized?
After fertilization, the newly formed cell undergoes rapid cell division, known as cleavage. This process does not involve cell growth and serves to increase the number of cells, while keeping the overall size of the embryo relatively constant. Cleavage helps to form a multicellular organism from a single-celled zygote.
Where does embryo development take place in oviparous animals?
In oviparous animals, embryo development takes place inside the egg outside the mother's body. The egg provides the necessary nutrients and protection for the developing embryo until it is ready to hatch.
What type of cell reproduction takes place once fertilization occurs?
Once fertilization occurs, the zygote undergoes mitotic cell division. This type of cell reproduction involves the duplication of the cell's genetic material and division of the cell into two identical daughter cells. This process continues as the zygote develops into an embryo.

An embryo is formed when fertilization takes place in a paramecium?

Where is mitosis currently taking place in human body?
it is a equational division it takes place in somatic cells of all part of the body....for growth...
List the main characteristics of dicotyledons?
1. Embryo has two cotyledons 2. Vascular bundles arranged in rings and are open 2. Secondary growth takes place
What occurs when uncontrolled division takes place?
Cancer is potentially a fatal form of uncontrolled cell division. Mitosis then becomes a weapon turned against the body, which spurs the growth of invasive tumors.
Does a chicken grow from the white or the yolk of an egg?
The germinal disc is located on the yolk, so that is where the initial cellular division takes place. But a chick can not develop with out both the yolk and the whites (albumen). The yolk is a high concentration of fats which provides energy for growth where as the albumen is high in proteins also needed for tissue growth.
What type of cell division takes place in the ganads?
Meiotic cell division takes place in the gonads in order to produce sex cells.
Which of the followiing processes takes place first in the developement of a human being?
embryo formation
Why is it important that cell growth in a multicellular organism be regulated so carefully?
In multicellular organisms, cell division must be carefully regulated to ensure that growth of the organism is coordinated, replacement of dead cells takes place in an orderly fashion, and repair of injured cells is initiated when needed. Cell division must also be halted when growth and repair are completed. Cell division is controlled by a variety of factors. One of the most important controls is carried out by molecules called growth factors.
How does the mother's choices she makes during pregnancy affect the growth and development of an embryo?
The embryo is obtains nutrients by drawing them from the mother's blood. Thus, whatever the mother takes in that alters chemical composition of her blood can potentially affect the embryo.
Where does new root growth take place?
New root growth takes place at the tip of the roots. It does because when roots get cut off new roots need to grow back in. So new root growth takes place at the tip of the cells. TO BE HONEST: I DON'T KNOW IF THIS IS RIGHT! BUT IT IS A GOOD GUESS!
What kind of reproduction takes place in cancer cells?
Division.
