Plant Cell Structures Under Microscope

What are the pair of structures that would provide a positive identification of a plant cell under a microscope?

A. endoplasmic reticulum, chloroplasts
B. large central vacuole, flagellum
C. chloroplast, large central vacuole
D. cytoskeleton, cell wall

Answer:

C. chloroplast, large central vacuole

When examining a plant cell under a microscope, the pair of structures that would provide a positive identification are the chloroplast and the large central vacuole. The chloroplast is the organelle responsible for photosynthesis, containing chlorophyll that gives plants their green color. The large central vacuole, on the other hand, plays a key role in maintaining turgor pressure and storing nutrients and waste products.

By observing these two structures in a plant cell under a microscope, you can confirm that it is indeed a plant cell. Other organelles like the endoplasmic reticulum, flagellum, and cytoskeleton are also present in plant cells but the presence of chloroplasts and large central vacuoles would be the most definitive in identifying a plant cell.
