An ecologist finds a unique substance growing on a rock. It has a large storage tank, a wall around the exterior, chloroplasts and a nucleus. Explain to the ecologist what type of cell this is (plant/animal and prokaryotic or eukaryotic) and how you know.

A eukaryotic cell. More specifically, a green plant.

Explanation:

Firstly, the presence of a nucleus tells us this is a eukaryotic cell, not a prokaryotic cell. Prokaryotic cells do not possess a nucleus and their genetic material is in the cytoplasm. Eukaryotic cells store their DNA in a nucleus.

The presence of a large storage tank (likely a central vacuole), a cell wall, and chloroplasts are all plant-cell specific features. The chloroplast is where photosynthesis takes place, so we know it must be a green plant.

its temperature is increasing. this causes molecular vibrations to increase.
