Question

unicellular organisms can be prokaryotic or eukaryotic, but all complex multicellular organisms are made up of eukaryotic cells. in general, prokaryotic cells are smaller and structurally less complex than eukaryotic cells, but they have more diverse ways to get energy and process nutrients. for example, there are prokaryotic organisms that can make their own food from carbon dioxide gas and therefore can live in extreme places that are inhospitable to most other organisms. decide whether each paragraph describes a prokaryotic or eukaryotic cell. complete the table. a cell is part of a plant’s stem. its dna is found within a nucleus. it contains other membrane - bound organelles, including chloroplasts that use sunlight to make food. 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 lives in a pond. it contains specialized parts surrounded by membranes that help it perform functions like producing energy, digesting food, and moving around.

Explanation:

1. Plant cells are eukaryotic. They have a nucleus - bound DNA and membrane - bound organelles like chloroplasts.
2. The cell living in a hot - spring with free - floating DNA in the cytoplasm and using sulfur for energy is prokaryotic as prokaryotes lack a nucleus and can have diverse energy - sources.
3. A cell with specialized membrane - bound parts is eukaryotic as membrane - bound organelles are characteristic of eukaryotic cells.

Answer:

1. Eukaryotic
2. Prokaryotic
3. Eukaryotic
