Chapter 3, Problem 1CYR

Which of the following is not a basic function shared by all cells?

a. Cell metabolism

b. Communication

c. Cell reproduction

d. Cell movement

e. Transport of substances through the cell

Summary Introduction

Introduction:

In a living organism, the basic units are cells. Based on the estimation, there are almost 10 trillion cells in a human body that work together to regulate homeostasis. Being the basic unit, the cells form a group, which can perform a specific role in the human body. The functions performed by the cells differ based on the group of cells.

Answer to Problem 1CYR

Correct answer:

Cell movement is not the basic function.

Explanation of Solution

Justification/Explanation for the correct answer:

Option (d) is cell movement. This is not a basic function of the cell. Cell movement is also called cell migration. Cell migration often results in the altering of cell morphology. Cell movement is often associated with microorganismsthat have cilia and flagella as their locomotory appendage. Not all cells can exhibit movement. Hence, option (d) is correct.

Explanation for the incorrect answers:

Option (a) is cell metabolism. Cell metabolism is a basic function of the cells. To maintain life, a cell must undergo various chemical reactions. These chemical reactions are called cell metabolism. Catabolism, anabolism, and oxidation–reduction reactions are various types of cell metabolism. So, it is an incorrect option.

Option (b) is communication. Cell communication is an important function of the cells. Not only the cell has to communicate with itself, but it also has to communicate with its surrounding. The communication within the cell and with its surrounding occur bymeans of electrical and chemical stimuli. So, it is an incorrect option.

Option (c) is cell reproduction. The cell reproduction is the basic function performed by the cell in a living system. The cells undergo cell division, which is the means of cell reproduction in the living organism. Cell division aids in development, growth, and regeneration. So, it is an incorrect option.

Option (e) is transport of a substance through the cell. The cells in our body are capable of producing compounds and transport them to the surrounding environment. Cells can also secrete the compound themselves and transport it to other cells. This is the basic function of z cell. So, it is an incorrect option.

Hence, options (a), (b), (c), and (e) are incorrect.

Conclusion

Hence, it can be concluded that cell movement is not the basic function. Even though some cells exhibit migration, not all the cells are capable of cell movement. Cell metabolism, communication, cell reproduction, and transport of a substance through the cells are the basic functions performed by the cell.
