MCQ on Fertilization

Plants live up to their moniker of “primary” or “universal” producers. They are indeed nature’s gift, providing us, humans, with life-giving necessities such as clothing, shelter, food, and oxygen. Plants, like all other living creatures, breathe, vegetate, germinate, excrete, and produce. Here, we’ll go over the fertilisation process in plants in detail, as well as answer some key questions.

Fertilization in plants can be defined as the process of amphimixis that occurs as a result of pollination and germination. After carpal pollination, the male gametes (called as pollen) infused with the feminine gametes generates a diploid zygote through a physicochemical process. The entire process takes place in a zygote, which then develops into a seed. Male gametes are delivered into female reproductive organs by pollinators during the process.

Q.23. How much time does it take for the egg to get fertilized?

1. 0-12 hours
2. 12-24 hours
3. 0-48 hours
4. 24-36 hours

Answer: 12-24 hours is Correct Answer because after being released from the ovary, the egg lives for about 12 to 24 hours. It disintegrates and is shed off by the uterine lining if it is not fertilised by this time.

Q.24. The fertilization process in humans takes place in several stages involving both chemical and Physical events.

1. True
2. False
3. None of these
4. Both 1 and 2

Q.25. How long does Sperm Live?

1. 12 hours
2. 24 hours
3. 48 hours
4. 72 hours

Answer: 72 hours is the Correct Answer Because the sperm survives for around 72 hours. To fertilise the egg, the sperm swims upwards to the fallopian tube. The earlier the sperm reaches the egg, the faster it swims.

Q.26. During Coitus the Population of Vagina with Semen is known as

1. Insemination
2. Outsemination
3. Copulation
4. Fertilization

Answer: Insemination is the Correct Answer Because Coitus, also known as copulation, is the release of sperm from the penis into the vaginal canal. The sperms, together with the rest of the semen, populate the vagina. Insemination is the term for this procedure.
