Chapter 1, Problem 1A

Summary Introduction

Introduction:

Living organisms vary from the single celled prokaryotic cells to the multicellular eukaryotic cells. Life or living organisms perform the basic functions of life that is respiration, locomotion, obtaining nutrition, response to stimulus, reproduction, growth and excretion. These functions distinguish them from non living entities.

Explanation of Solution

Correct answer:

The entire living organisms do not care for their offspring. Therefore, option (c) is correct.

Explanation for the correct answer:

The organisms, such as mammals, fishes, and birds care for their offspring until they get mature and are able to survive in nature. Some of the organisms do not care for their offspring. Instead, they leave them after the offspring’s are formed.

Option (c) is given as “care for their offspring”.

As, “all of the offspring are not cared by their living organisms”, is the right answer.

Hence, option (c) is correct.

Explanations for incorrect answers:

Option (a) is given as “organization”. The living organisms have a certain level of organization of biomolecules, cells, and tissues. The high level of organization helps the organisms in their functioning. So, it is a wrong answer.

Option (b) is given as “acquisition of materials and energy”. The living organisms consume food and generate energy from their cellular activities. So, it is a wrong answer.

Option (d) is given as “reproduction”. All the living organisms reproduce and produce their offspring. Reproduction is an important key to the survival of organisms.

So, it is a wrong answer.

Option (e) is given as “responding to the environment”. All the living organisms respond to the external stimulus. So, it is a wrong answer.

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

Conclusion

All the progeny are not are not taken care by their parental living organisms.
