Fertilization begins when the outer membrane of one sperm cell and the secondary oocyte touch. At this time, physical and chemical changes across the oocyte surface produce a fertilization envelope, which prevents other sperms from entering the same egg cell.

Summary Introduction

Introduction:

Fertilization begins when the outer membrane of one sperm cell and the secondary oocyte touch. At this time, physical and chemical changes across the oocyte surface produce a fertilization envelope, which prevents other sperms from entering the same egg cell.

Expert Solution & Answer

Answer to Problem 1MCQ

Correct answer:

The fertilized egg cell is the result of fertilization.

Therefore, option b is correct.

Explanation of Solution

Reason for the correct statement:

As the sperms reach the oocyte, they show fusion. Out of 100 million sperm, only 200 approach the egg cell and only one fuses with the egg. The sperm needs to penetrate inside the oocyte through two layers present on oocyte. This fusion of sperm cell and egg cell is known as fertilization, which results into the zygote. Hence, the zygote is the product of fertilization.

Hence, option b is correct.

Reasons for incorrect statements:

Option (a) is given as “The male gamete”.

The sperms are male gametes, which are flagella like structures. They are involved in the fusion and fertilize the oocyte. Hence, it is a wrong answer.

Option (c) is given as “The female germ cell”.

The female germ cells are diploid and are present in the ovaries of females. They are not related to zygote. Hence, it is a wrong answer.

Option (d) is given as “The female gamete”.

The oocytes are the female gametes, which consist of jelly membranes for their protection and are fertilized by sperms during fertilization, but they are not the product of fertilization. Hence, it is a wrong answer.

Hence, options (a), (c), and (d) are incorrect.

Conclusion

The sperm cells and oocyte fuse together to form a fertilized egg called as zygote. A zygote is the product of fertilization.

After you feel comfortable with your counting method and identifying cells in the various stages of mitosis, use the four images below of whitefish blastula to count the cells in each stage until you reach 100 total cells, recording your data below in Data Table 1. (You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage. (Divide total of stage by overall total of 100 and then multiply by 100 to obtain percentage.)
