Question

a cell lives in a pond. it contains specialized parts surrounded by membranes that help it perform functions like producing energy, digesting food, and moving around. a cell lives in a boiling hot spring. it uses chemicals like sulfur for energy instead of sunlight or food. its dna floats freely inside of its cytoplasm. a cell is part of a plants stem. its dna is found within a nucleus. it contains other membrane - bound organelles, including chloroplasts that use sunlight to make food.

Explanation:

1. Eukaryotic cells have membrane - bound organelles. The first cell has specialized membrane - bound parts for energy production etc., and the third cell has a nucleus and chloroplasts (membrane - bound), so they are eukaryotic.
2. Prokaryotic cells lack a nucleus and membrane - bound organelles and have free - floating DNA. The second cell has free - floating DNA and uses sulfur for energy, so it is prokaryotic.

Answer:

1. Eukaryotic
2. Prokaryotic
3. Eukaryotic
