Question

Chapter 33, Problem 1U

Summary Introduction

Introduction:

Animals are multicellular, heterotrophic, sexually reproducing organisms that are capable of locomotion.

Expert Solution & Answer

Answer to Problem 1U

Correct answer:

Lack of cell wall is a characteristic unique to all the animals. Therefore, option c. is correct.

Explanation of Solution

Reason for the correct statement:

Animals differ from all other multicellular organisms in one aspect that are they lacking a rigid cell wall. All other multicellular organisms such as plants, fungi, and others possess cell walls that differ in their compositions. The plants have cell walls made up of cellulose, while the fungi possess the cell wall made up of chitin.

Option c. is given as “Lack of cell walls”.

As, “the characteristic unique to all animals is lack of cell walls in their cells”, is the right answer.

Hence, option c. is correct.

Reason for the incorrect statements:

Option a. is given as “Sexual reproduction”.

Sexual reproduction is not unique to animals as it can be seen in other organisms also such as plants and fungi. So, it is a wrong answer.

Option b. is given as “Multicellularity”.

Multicellularity is not unique to animals as it can be seen in plants and fungi also. So, it is a wrong answer.

Option d. is given as “Heterotrophy”.

Heterotrophy is not unique to animals as it can be seen in other organisms also such as fungi. So, it is a wrong answer.

Hence, options a., b., and d. are incorrect.

Conclusion

The lack of cell walls is a characteristic unique to the animals.
