Which two structures would provide a positive identification of an animal cell under a microscope?

Question

Question 2 options:

flagellum, lysosome

ribosome, lysosome

nucleus, vesicle

chromatin, chloroplast

Answer 1

To provide a positive identification of an animal cell under a microscope, the most appropriate structures from the options given would be nucleus and vesicle.

Here's why:

• Nucleus: This is a defining feature of eukaryotic cells, including animal cells. It contains the cell's genetic material.

• Vesicle: While not exclusive to animal cells, vesicles can be found in animal cells for transporting materials, thus supporting identification.

The other options either include structures not specific to animal cells (like chloroplasts, which are found in plant cells) or structures that are not definitive identifiers (like ribosomes). So, the best choice is nucleus and vesicle.
