Question

select the true statements.
all cells in the human body are small and round.
the human body contains different types of cells.
a cells structure allows it to carry out a specific function.
adipocytes have a long axon to communicate with other cells.

Explanation:

• Human cells vary in shape and size (e.g., long, thread-like muscle cells, flat skin cells), so the first statement is false.
• The human body has hundreds of specialized cell types (e.g., neurons, muscle cells, red blood cells), so the second statement is true.
• Cell structure is tightly linked to function (e.g., red blood cells' biconcave shape enables oxygen transport), so the third statement is true.
• Adipocytes are fat cells that store energy; long axons are a feature of neurons, not adipocytes, so the fourth statement is false.

Answer:

• Correct statements:

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

• Incorrect statements:

1. All cells in the human body are small and round.
2. Adipocytes have a long axon to communicate with other cells.
