Which of the following statements is NOT part of the cell theory?

a. All organisms are composed of one or more cells.

b. Cells come from other cells by division.

c. Cells are the smallest living things.

d. Eukaryotic cells have evolved from prokaryotic cells.

Expert Solution & Answer

Summary Introduction

Introduction:

The cell theory explains that all the living organisms are composed of cells and cells are the basic unit of life. The cell theory was proposed by German botanist Matthias Schleiden and German physiologist Theodor Schwann. They observed that all plant and animal tissues consists of aggregates of individual cells, which are separate and independent units. These individual units were cells and thus, the cell theory was proposed.

Answer to Problem 1U

Correct answer:

The cell theory explains that all the living organisms are composed of one or more cells, which are the smallest living things, and cells arise from preexisting cells by cell division. Therefore, option d is the correct answer.

Explanation of Solution

Reason for the correct statement:

The cell theory includes three principles: all the living organisms are composed of one or more cells, cells are the smallest living things and cells arise from other cells by the process of cell division.

Option d is given as “Eukaryotic cells have evolved from prokaryotic cells.”

As, the statement “eukaryotic cells have evolved from prokaryotic cells” is not a part of the cell theory, it is the right answer.

Hence option d is correct.

Reasons for the incorrect statements:

Option a is given as “All organisms are composed of one or more cells.”

The cell theory explains the observations that all living organisms are made up of one or more cells. This statement is one of the principles included in the cell theory. So, it is a wrong answer.

Option b is given as “Cells come from other cells by division.”

The cells increase in their number by the process of cell division by which the new cells arise from pre-existing cells. This statement is also one of the principles included in the cell theory. So, it is a wrong answer.

Option c is given as “Cells are the smallest living things.”

All living organisms like plant and animal tissues consist of aggregates of individual cells, which are separate and independent units. These units are called cells, which are the smallest living things. This statement is also one of the principles included in the cell theory. So, it is a wrong answer.

Hence options a, b, and c are incorrect.

Conclusion

The cell theory is a basic principle of biology that explains about the basic functional and structural unit of life called a cell.
