You have discovered a new organism living in tide pools at your favorite beach. Every so often, one of the creature’s appendages will break off and gradually grow into a whole new organism, identical to the first. This is an example of
a. sexual reproduction.
b. fission.
c. budding.
d. parthenogenesis.
Introduction:
The biological process of the formation of offspring from their parents is known as reproduction. It is a fundamental feature of life. Reproduction occurs in two forms, asexual reproduction and sexual reproduction.
Answer to Problem 1U
Correct answer:
The creature appendages break off and gradually grow into a whole new organism. This is an example of budding. Therefore, option c. is correct.
Explanation of Solution
Reason for the correct statement:
Budding is a type of asexual mode of reproduction. In this type of reproduction, the new organism develops from the bud or outgrowth occurs because of the division of cells.
Option c. is given as “budding”.
As “budding is the reason for the gradual growth of broken appendage into the whole organism”, it is the right answer.
Hence, option c. is correct.
Reason for the incorrect statements:
Option a. is given as “sexual reproduction”.
The organism is produced by the fusion of gametes, involving male’s sperm and female’s egg. Thus, it is a wrong answer.
Option b. is given as “fission”.
It is a type of sexual reproduction in which the cell divides into two parts and each part has the potential to grow into the organism of the same size as of the original. Thus, it is a wrong answer.
Option d. is given as “parthenogenesis”.
It is the type of asexual reproduction in which the development of the organism takes place from the unfertilized egg. Thus, it is a wrong answer.
Hence, options a., b. and d. are incorrect.
Conclusion:
Budding is the type of asexual reproduction that results in the gradual growth of a new organism from the broken appendages.

- The difference between asexual and sexual reproduction is that A. asexual reproduction occurs only in haplontic organisms, whereas sexual reproduction occurs only in diplontic organisms. B. asexual reproduction results from meiosis, whereas sexual reproduction results from mitosis. C. asexual reproduction occurs only in bacteria, whereas sexual reproduction occurs in plants and animals. O D. asexual reproduction results from the fusion of two gametes, whereas sexual reproduction produces clones of the parent organism. O E. asexual reproduction results in an organism that is identical to the parent, whereas sexual reproduction results in an organism that is not identical to either parent.arrow_forwardWhat are some benefits that come with sexual reproduction? Please select all correct answers. a. Sexual individuals must reproduce twice as much. b. Sex makes species less vulnerable to parasites. c. Males and females must expend energy finding each other. d. It potentially makes dangerous alleles less dangeous.arrow_forwardSperm cell fertilizes an egg which later becomes a new individual.

- Is this true or false? a. Fertilization is followed by a cleavage, a period of rapid cell division without growth. b. From the process above, this results in the production of a large number of cells called blastomeres. c. In sexual reproduction, the offspring have the same combinations of genes as their parents. d.
