Question

A student uses a microscope to observe a single-celled organism that can move. The organism contains a nucleus and many chloroplasts. Based on the observations, the student claims the organism is not a bacterium. Which observation best supports the student's claim?

Answer 1

Answer:

The organism is not a bacterium since it contains chloroplasts and nucleus.

Explanation:

Bacterial cells and prokaryotes do not contain a well defined nucleus and do not possess other membrane bound organelles. They usually have a single chromosome which contains circular DNA. They do not possess chloroplasts.

Chloroplasts are present in eukaryotic plant cells which help in the process of photosynthesis. They help absorb sunlight and contain the pigment chlorophyll.

The student is examining a eukaryotic cell.
