Question

which of the following membrane - bound organelles do only plant cells have? (1 point)
○ vacuole
○ chloroplast
○ mitochondria
○ nucleus

Explanation:

To determine the organelle unique to plant cells:

• Vacuole: Both plant and animal cells have vacuoles (plant vacuoles are larger, but not exclusive).
• Chloroplast: Only plant (and some algae) cells have chloroplasts for photosynthesis; animal cells lack them.
• Mitochondria: Present in both plant and animal cells (for cellular respiration).
• Nucleus: Present in both plant and animal cells (controls cell activities).

Thus, chloroplast is the organelle only plant cells have.

Answer:

B. Chloroplast (assuming the options are labeled as A: Vacuole, B: Chloroplast, C: Mitochondria, D: Nucleus; adjust labels as per original formatting if different, but the correct option is the one with "Chloroplast").
