Every organisms present in the environment contains cell. The cell is the basic “fundamental unit” of life. Cell performs a number of important functions. These are termed as cellular activities. Reproduction is also an important cellular activity. All the new cells are formed from the old cell. The process by which a cell produces its progenies is termed as reproduction.

Expert Solution & Answer

Answer to Problem 1SA

Correct answer:

The single-celled prokaryotes reproduce asexually by mitosis and cytoplasmic division. Hence, the correct answer is option a.

Explanation of Solution

Reason for correct answer:

Option a. is given as “asexual reproduction of single-celled prokaryotes”.

The prokaryotes are simple organisms that lack a well-defined nucleus. The genetic material in prokaryotes lies freely in the cytoplasm. The unicellular prokaryotes reproduce asexually through mitosis and cytoplasmic division. Mitosis is a process in which the nucleus of the cell divides. Mitosis has the capability to maintain the number of chromosomes present inside the nucleus. The cytoplasmic division is the process in which the cytoplasm of the parental cell divides into two equal parts. These two parts are termed as daughter cells.

Reason for incorrect answer:

Option b. is given as, “development and tissue repair in multicelled species”.

Mitosis and cytoplasmic division are the methods of asexual reproduction. Mitosis is also involved in the development and tissue repair mechanisms in some multicellular organisms. However, the cytoplasmic division has no role in the development and tissue repair mechanism. Hence, option b. is incorrect.

Option c. is given as, “sexual reproduction in plants and animals”.

Mitosis and cytoplasmic division are the two ways of asexual reproduction. This indicates that mitosis and cytoplasmic division are not the methods of sexual reproduction. Hence, option c. is incorrect.

Hence, the options b., and c. are incorrect.

Conclusion

Mitosis and the cytoplasmic division are the two ways in which a unicellular prokaryote reproduces asexually. Thus, the correct option is a.

For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible. Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population produced using single seed…
