Chapter 33, Problem 1TY

Summary Introduction

Introduction: Animals have a number of characteristics that distinguish them from other organisms. The characteristics include multicellularity, the presence of an extracellular matrix, heterotrophic feeding, and possession of nervous and muscle tissues.

Expert Solution & Answer

Answer to Problem 1TY

Correct answer:

Possession of cell walls is not a distinguishing characteristic of animals. Hence, the correct answer is option b.

Explanation of Solution

Reason for correct answer:

Animals can be defined as multicellular heterotrophs with cells that lack cell walls, the capacity to move at some point in their life cycle, and the ability to reproduce sexually.

Option b. is given as “possession of cell walls”.

Animal cells lack a cell wall and are quite flexible. The cells of plants, fungi, bacteria, archaea, and most protists possess a rigid cell wall. Hence, the correct answer is option b.

Reasons for incorrect answer:

Option a. is given as, “the capacity to move at some point in the life cycle”.

Most animals have a muscle system, which allows them to move in their environment. Hence, option a. is incorrect.

Option c. is given as, “multicellularity”.

Animals are multicellular in nature, for example sponges (a simple type of animal). Hence, option c. is incorrect.

Option d. is given as, “heterotrophy”.

Animals obtain their food by eating other organisms. Plants and algae are grouped as autotrophs since they produce their own food. Hence, option d. is incorrect.

Option e. is given as, “All of the above are characteristics of animals”.

Animal cells do not possess a cell wall. Therefore, presence of cell wall in animal cells is not considered as a distinguishing characteristic of animals. Hence, option e. is incorrect.

Hence, the options a., c., d., and e. are incorrect.

Conclusion

Thus, possession of cell walls is not a distinguishing characteristic of animals.
