2.9 speicalized cells

Question 1

Which type of cell is responsible for transmitting electrical signals in the body?

Answer 1

Nerve cells (neurons)

Question 2

Which specialized cell is involved in the movement of the body?

Answer 2

Muscle cells

Question 3

All cells in the human body have the same function.

Answer 3

False

Question 4

Bone cells are specialized to create and maintain a hard mineral structure. T or F

Answer 4

True

Question 5

How are red blood cells specialized for their function?

Answer 5

Red blood cells are disc-shaped, lack a nucleus to carry more hemoglobin, and are flexible to move through narrow blood vessels.

Question 6

How are root hair cells in plants specialized for their function?

Answer 6

Root hair cells have long projections that increase surface area to absorb more water and nutrients from the soil.

Question 7

A person has anemia, meaning their red blood cells have less hemoglobin. How might this affect their body?

Answer 7

their red blood cells cannot carry as much oxygen, leading to fatigue and weakness because tissues receive less oxygen for energy production.

Question 8

Compare the structure and function of three specialized cells: red blood cells, nerve cells, and muscle cells.

Answer 8

Red blood cells are disc-shaped and lack a nucleus to maximize hemoglobin for oxygen transport.
Nerve cells have long axons to transmit electrical signals over long distances.
Muscle cells contain many mitochondria and protein fibers to contract and enable movement.
