Fertilization starts at 7 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Fertilization.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 10
Describe the main steps involved in the process of fertilization in animals.
Describe the process of double fertilization in flowering plants.
Describe the role of the acrosome in fertilization.
Describe what happens to the zygote immediately after fertilization.
Explain the difference between internal and external fertilization.
Explain the importance of genetic variation resulting from fertilization.
Explain why external fertilization is more common in aquatic animals.
A scientist observes that in a certain species of fish, fertilization occurs outside the body and the eggs are released into the water. What are two major challenges faced by gametes in this type of fertilization, and how might the species overcome them?
During fertilization, the sperm contributes which of the following to the zygote? (1) Only DNA (2) DNA and mitochondria (3) DNA and centrioles (4) Only centrioles
In which type of fertilization are the chances of survival of the offspring generally higher? (1) Internal fertilization (2) External fertilization
Which event occurs first during fertilization? (1) Fusion of nuclei (2) Penetration of egg membrane by sperm (3) Formation of zygote (4) Cleavage of zygote
Which of the following best describes the zygote? (1) Haploid (2) Diploid (3) Triploid (4) Polyploid
Fertilization restores the ________ number of chromosomes in the zygote.
Fill in the blank: In flowering plants, the male gamete is carried to the female gamete by the process of ________.
Fill in the blank: In humans, the sperm is ________ (haploid/diploid) and the zygote is ________ (haploid/diploid).
Fill in the blank: The process by which the sperm penetrates the egg is called ________.
True or False: Fertilization can occur without the presence of both male and female gametes.
True or False: Fertilization restores the diploid number of chromosomes in the zygote.
True or False: In animals with external fertilization, large numbers of eggs and sperm are released to increase the chances of fertilization.
True or False: In plants, fertilization occurs in the ovary.
