Question

cells are often modeled as small round structures. but not all cells are round! specialized cells have unique structures that help them perform specific functions in the body.
read about three different types of human cells.
adipocytes are also known as fat cells. they contain one or more fat droplets. adipocytes store energy, insulate the body from temperature changes, and provide cushioning for the body’s organs.
skeletal muscle cells are long and thin. they can shorten and lengthen. skeletal muscle cells are responsible for almost all voluntary movement in the body.
neurons are brain cells with a long extension called an axon. since the axon is long, neurons can extend from the brain and spinal cord to other parts of the body to send and receive signals.
select the true statements.
the human body contains different types of cells.
a cell’s structure allows it to carry out a specific function.
all cells in the human body are small and round.
adipocytes have a long axon to communicate with other cells.

Explanation:

• The text explicitly describes three distinct human cell types (adipocytes, skeletal muscle cells, neurons), confirming the first statement is true.
• Each cell's unique structure is tied to its function: adipocytes store energy with fat droplets, long thin muscle cells enable movement, and neurons use axons for signaling, so the second statement is true.
• The opening text states "not all cells are round", so the claim that all human cells are small and round is false.
• The axon is a feature of neurons, not adipocytes, so the fourth statement is false.

Answer:

1. The human body contains different types of cells.
2. A cell's structure allows it to carry out a specific function.
