Which of the following shows the levels of organization in a multi-cell organism from the smallest level to the largest level?

A- cell, tissue, organ, organ system, organism

B- organism, organ system, organ, tissue, cell

C- tissue, cell, organ, organ system, organism

D- cell, organ, organ system, tissue, organism

(My guess is A, but I am not very sure.)

I agree.

Thank you :)

To determine the correct answer, let's first understand what each term represents and then arrange them in the correct order.

A cell is the basic building block of life, and it is the smallest level of organization. Tissues are groups of cells working together to perform a specific function. Organs are made up of multiple tissues working together to perform a specific function. Organ systems are groups of organs working together to perform a particular task. An organism is an individual living thing that consists of multiple organ systems working together.

Applying this knowledge, we can now arrange the terms in the correct order:

A - cell, tissue, organ, organ system, organism

Now we can compare the options with our arrangement:

A - cell, tissue, organ, organ system, organism (matches our arrangement)

B - organism, organ system, organ, tissue, cell (order is reversed)

C - tissue, cell, organ, organ system, organism (order is different)

D - cell, organ, organ system, tissue, organism (order is different)

Based on the comparison, it is clear that the correct answer is A. The levels of organization in a multicellular organism are arranged from the smallest level to the largest level as: cell, tissue, organ, organ system, organism.
