Students are examining cells from a certain organism under a microscope. They notice mitochondria, a nucleus, chloroplasts, and ribosomes in each cell. What type of cells are they viewing and how do you know?(1 point)
Responses
Plant cells due to the observation of mitochondria
Plant cells due to the observation of mitochondria
Animal cells due to the observation of ribosomes
Animal cells due to the observation of ribosomes
Prokaryotic cells due to the observation of mitochondria
Prokaryotic cells due to the observation of mitochondria
Plant cells due to the observation of chloroplasts
Responses
Plant cells due to the observation of mitochondria
Plant cells due to the observation of mitochondria
Animal cells due to the observation of ribosomes
Animal cells due to the observation of ribosomes
Prokaryotic cells due to the observation of mitochondria
Prokaryotic cells due to the observation of mitochondria
Plant cells due to the observation of chloroplasts
The students are viewing plant cells due to the observation of chloroplasts. Chloroplasts are specific to plant cells and are responsible for photosynthesis. The presence of mitochondria and ribosomes does not distinguish the cells as plant or animal, as both types have those organelles.
