Question

what are the three organelles found only in plant cells?
a chloroplasts, cell wall, large central vacuole
b chloroplasts, cell wall, mitochondria
c chloroplasts, ribosomes, large central vacuole
d chloroplasts, mitochondria, and endoplasmic reticulum

Explanation:

• Chloroplasts: These are the sites of photosynthesis in plant cells, converting light energy into chemical energy. Animal cells lack chloroplasts as they do not perform photosynthesis.
• Cell Wall: Plant cell walls provide structural support and protection. They are made of cellulose. Animal cells have only a cell membrane, not a cell wall.
• Large Central Vacuole: In plant cells, the large central vacuole stores water, nutrients, and waste products. It also helps maintain turgor pressure. Animal cells have small, multiple vacuoles or sometimes no vacuoles at all.
• Mitochondria: Present in both plant and animal cells as they are the power - houses of the cell (site of cellular respiration). So options B and D are incorrect.
• Ribosomes: Found in both plant and animal cells (site of protein synthesis). So option C is incorrect.

Answer:

A. Chloroplasts, Cell Wall, Large Central Vacuole
