Question 1 of 10

1. Question
1 point(s)
Why do mature red blood cells lack a nucleus?
- To allow cells to divide more rapidly through the process of mitosis.
- To reduce the size of cells so they can pass through narrow blood capillaries.
- To reduce the rate of cellular respiration so that oxygen is not used by the cells themselves.
- To allow cells to load more hemoglobin for gas transport.
Correct

Incorrect
Question 2 of 10

2. Question
1 point(s)
What is the main characteristic of white blood cells that allows them to move into the intercellular space to hunt pathogens?
- Has a long tail or flagellum for swimming.
- The ability to change shape or be amoeboid.
- Has a very high density of mitochondria for energy.
- Presence of pores in the cell membrane for pathogen diffusion.
Correct

Incorrect
Question 3 of 10

3. Question
1 point(s)
Which cell has a high density of mitochondria to support its function?
- xylem vessels
- Muscle cells
- Red blood cells
- Epidermal cells of the skin
Correct

Incorrect
Question 4 of 10

4. Question
1 point(s)
How is palisade mesophyll cell structure adapted to maximize photosynthesis?
- Cylindrical and arranged vertically and closely.
- Has a thick cell wall with lignin for support.
- Absence of chloroplasts to make room for large vacuoles.
- Loosely arranged to create large air spaces.
Correct

Incorrect
Question 5 of 10

5. Question
1 point(s)
What is the main role of lignin in the xylem vessels of plants?
- Provides nutrients to surrounding cells.
- Allows cytoplasm to move more smoothly.
- Prevents channels from collapsing due to negative water pressure.
- Acts as a catalyst in active water transport.
Correct

Incorrect
Question 6 of 10

6. Question
1 point(s)
Why do root hair cells have long and fine projections?
- To penetrate the hard rock layer in the soil.
- To reduce the rate of transpiration in the roots.
- To increase the ratio of total surface area to volume (SSA/I).
- To store excess water during the dry season.
Correct

Incorrect
Question 7 of 10

7. Question
1 point(s)
Pancreatic cells have a high density of Rough Endoplasmic Reticulum (RER). What is the main function of these cells?
- Produces ATP energy for body activities.
- Synthesizes and secretes digestive enzymes or hormones.
- Stores glucose in the form of glycogen.
- Carry out the detoxification process of poisons in the blood.
Correct

Incorrect
Question 8 of 10

8. Question
1 point(s)
What happens if the enzymes in the lysosomes fail to function as in Tay-Sachs disease?
- Accumulation of lipids that are not broken down will damage nerve cells.
- Cells will lack energy to carry out activities.
- The rate of photosynthesis in plant cells will decrease.
- Proteins cannot be synthesized by the cell.
Correct

Incorrect
Question 9 of 10

9. Question
1 point(s)
Why do guard cells have thicker cell walls on the inside than on the outside?
- To allow the cell to curve outward when it becomes stiff.
- To protect the stoma from being entered by pests.
- To store more chloroplasts inside.
- To prevent water from seeping out through osmosis.
Correct

Incorrect
Question 10 of 10

10. Question
1 point(s)
Which feature helps nerve cells (neurons) send information quickly to distant parts of the body?
- Has fine pores along the length of the axon for ion diffusion.
- Has a large cell body for storing information.
- Has many nuclei for coordinating information.
- Has long, myelin-coated axon projections.
Correct

Incorrect
