Question

The union of ovum and sperm is known as

• A. . Placentation
• B. . Ovulation
• C. . Folification
• D. . Fertilization

Hint:

Remember the distinct stages of reproduction: Ovulation (egg release), Fertilization (sperm-egg fusion), Implantation (zygote attachment), Placentation (placenta formation).

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
The question asks for the biological term that describes the fusion of an ovum (egg cell) and a sperm cell.

Step 3: Detailed Explanation:
* Fertilization: This is the process where a male gamete (sperm) fuses with a female gamete (ovum or egg) to form a zygote. This event marks the beginning of embryonic development in sexual reproduction.
* Placentation: This refers to the formation or arrangement of the placenta in the uterus, which provides nourishment to the developing fetus.
* Ovulation: This is the process by which a mature egg is released from the ovary.
* Folification: This term is not standard in biology. It might be a misspelling or an unfamiliar term. The process of follicle development is folliculogenesis.
Therefore, the union of ovum and sperm is known as fertilization.

Step 4: Final Answer:
The union of ovum and sperm is known as Fertilization.
