Chapter 1, Problem 1SQ

Summary Introduction

Introduction:

All the substances present in the environment are composed of elements. Biologist gave a sequence of an organization that is followed by every substance. This is known as the “level of organization.”

Answer to Problem 1SQ

Correct answer:

The fundamental building blocks of all matter are atoms. Hence, the correct answer is option a.

Explanation of Solution

Reason for correct answer:

Option a. is given as “Atoms”

The basic level of the organization includes “atoms, molecules, cells, tissues, organs, organ system, organisms, population, community, ecosystem, and biosphere.” The basic, fundamental building blocks that form all matter is an atom. The interaction of atoms results in the formation of molecules. Molecules interact to form cells. The cell is the basic “fundamental unit” of every living organism. The cellular interaction forms tissues and tissues link together to form organs. This formation cycle continues to grow and ultimately forms biosphere. The biosphere is the largest level of organization, and it contains all the substances (both living and non-living) that are present in the environment. Hence, option a. is correct.

Reason for incorrect answer:

Option b. is given as, “Molecules.”

Molecules are one of the smaller units that form substance. However, they are not the fundamental one. Molecules are formed by the interaction of atoms. This indicates that molecules are not the fundamental building blocks of all matter.

Hence, option b. is incorrect.

Option c. is given as, “Cells.”

Cells are the basic “fundamental unit” of life. They are the smallest unit for the formation of organisms but not mater. Cells are formed by molecules, and molecules are composed of atoms. This indicates that cells are not the fundamental building blocks of all matter. Hence, option c. is incorrect.

Option d. is given as “Organisms.”

Organisms are larger units. They contain cells, tissues, organ, and organ system. The basic unit that forms an organism is a cell. However, atoms are the building blocks of the cell. This indicates that organisms are not the fundamental building blocks of all matter. Hence, option d. is incorrect.

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

Conclusion

Atoms are the fundamental building blocks of all matters. Thus, the correct option is a.
