Chapter 36, Problem 1TYU

Summary Introduction

Introduction:

Parthenogenesis is a mode of asexual reproduction in which an egg develops into an embryo without fertilization.

Expert Solution & Answer

Answer to Problem 1TYU

Correct answer:

Only a single parent is required for parthenogenesis, as fertilization is not needed. Hence, fertilization is not required for the development of an egg into an embryo. Therefore, option (D) is correct.

Explanation of Solution

Reason for the correct statement:

Parthenogenesis is observed in lower plants and animals. The egg or gamete produced by the female develops into a complete organism without fusion with the male gamete.

Option (D) is given as “An egg develops without being fertilized”.

“In parthenogenesis, an egg develops without being fertilized”. Thus, it is the right answer.

Hence, option (D) is correct.

Reasons for the incorrect statements:

Option (A) is given as “An individual may change its sex”.

An individual changing its sex is not parthenogenesis; it is called sequential hermaphroditism. Therefore, it is a wrong answer.

Option (B) is given as “Groups of cells grow into new individual”.

In parthenogenesis, a single egg develops into a complete organism, not from the groups of cells. Therefore, it is the wrong answer.

Option (C) is given as “An organism is first a male and then a female”.

An organism that develops as a male, and then develops into a female is called a protandrous hermaphrodite. Therefore, it is the wrong answer.

Hence, options (A), (B) and (C) are incorrect.

Conclusion

Parthenogenesis is an asexual mode of reproduction in which an organism develops from an unfertilized egg.

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.) Data Table 1Stage Totals PercentInterphase Mitosis: Prophase Metaphase Anaphase Telophase Cytokinesis Totals 100 100% To find the length of time whitefish blastula cells spend in each stage, multiply the percent (recorded as a decimal, in other words take the percent number and divide by 100) by 24 hours.
