Morula is a developmental stage:a)Between the zygote and blastocystb)Between the blastocyst and gastrulac)Between implantation and parturitiond)After the implantationCorrect answer is option 'A'. Can you explain this answer?

Question

Answer

Options A.morula is development stage embryo with 8 to 16blastomeres is called morula .morula is the solid mass of cells and is mulberry.

Answer

Option-a between zygote and blastocyst
as morula is the 8-16celled stage and blastula is 32 celled stage this both results due to cleavagic div. in zygote 1st Cleavagic division occurs 30min after fertilization whereas 2nd one takes place after10 hrs the 1st one

Answer

After fertilization, zygote  is formed. Zygote undergoes, mitotic divisions, called cleavage, to form 2,4,8 and 16 daughter cells called blastomeres .These divisions start when zygote is moving towards uterus.It is called morula at 8 - 16 cell stage and it continues to divide to form blastocyst.

Answer

Morula is a developmental stage:

Introduction:
The process of embryonic development involves a series of stages where the fertilized egg undergoes multiple divisions and transformations to eventually form a fully developed organism. One of these stages is known as the morula stage. In this stage, the embryo is composed of a solid ball of cells.

Explanation:
The correct answer is option 'A' - Between the zygote and blastocyst. Let's understand why this is the correct answer.

Formation of the zygote:
After fertilization, when the sperm fuses with the egg, the zygote is formed. The zygote is a single-celled structure that contains the complete set of genetic material from both parents.

Division and formation of morula:
The zygote undergoes a series of cell divisions through a process called cleavage. These divisions result in the formation of a solid ball of cells known as the morula. The morula is typically composed of around 16 to 32 cells.

Characteristics of morula:
1. Solid ball of cells: The morula is a compact cluster of cells with no fluid-filled cavity inside.
2. Similar-sized cells: The cells in the morula are of similar size and shape, indicating that they are undifferentiated at this stage.

Transition to blastocyst:
After the morula stage, the embryo undergoes further development and transforms into a blastocyst. This transition occurs through a process called blastulation.

Conclusion:
In conclusion, the morula is a developmental stage that occurs between the zygote and blastocyst. It is characterized by a solid ball of cells and precedes the formation of a fluid-filled cavity known as the blastocyst. Understanding the sequence of embryonic development is crucial in studying the formation of different tissues and organs in an organism.
