Which of the following represents the correct order of organization of an animal’s body?
a. | Cells; organs; organ systems;tissues |
b. | Cells; tissues; organ system; organs |
c. | Tissues; cells; organs; organ systems |
d. | Cells; tissues; organs; organ systems |
Introduction:
The body of animals can be described in terms of the organizational hierarchy. All the cells are arranged into a higher level of organization to perform specific functions within the body of the organisms.
Answer to Problem 1MCQ
Correct answer:
Cells; tissues; organs; organ systems is the correct order of organization in the body of an animal. Hence, the correct answer is option d.
Explanation of Solution
Reason for correct answer:
Option d. is given as, “Cells; tissues; organs; organ systems”.
Cells are the basic unit of life that group to form tissues. These tissues perform specific functions in the body. Tissue combines in groups to create organs to perform particular tasks. The formation of an organ system occurs when all the organs combine to work.
Reasons for incorrect answer:
Option a. is given as, “Cells; organs; organ systems; tissues.”
In this particular option, organs are coming prior to the formation of tissues. Hence, option a. is incorrect.
Option b. is given as, “Cells; tissues; organ system; organs.”
Organ systems are not formed prior to the development of organs. Hence, option b. is incorrect.
Option c. is given as, “Tissues; cells; organs; organ systems.”
A group of cells form tissues. The formation of tissues cannot happen prior to cells. Hence, option c. is incorrect.
Hence, the options a., b., and c. are incorrect.
The correct order of sequence hierarchy in the body of an animal is cells; tissues; organs; organ systems. Thus, the correct answer is option d.
