Statement: The correct statement about the morula in humans is option B: It has almost equal quantity of cytoplasm as an uncleaved zygote but much more DNA.
Explanation:
The development of an embryo begins with the fertilization of an egg by a sperm, resulting in the formation of a zygote. The zygote then undergoes a series of cell divisions to form a morula, which is a solid ball of cells.
To understand the correct statement, let's compare the characteristics of a morula with an uncleaved zygote:
Uncleaved zygote:
- It is a single cell formed after fertilization.
- It has a relatively large quantity of cytoplasm, which is the fluid component of the cell.
- It has a small amount of DNA, which contains the genetic material.
Morula:
- It is a cluster of cells, formed by the division of the zygote.
- The morula has a similar amount of cytoplasm as an uncleaved zygote.
- However, it contains much more DNA compared to an uncleaved zygote because the DNA is replicated during cell division.
Therefore, the correct statement is option B: The morula has almost equal quantity of cytoplasm as an uncleaved zygote but much more DNA.
