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 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. 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:

• Prokaryotic cells have DNA that floats freely in the cytoplasm and lack membrane - bound organelles. The first cell described has DNA floating freely and uses chemicals like sulfur for energy (a more diverse energy - getting way which is common in prokaryotes).
• Eukaryotic cells have DNA in a nucleus and membrane - bound organelles. The second cell is part of a plant (a multicellular organism which is made of eukaryotic cells) and has a nucleus and chloroplasts (a membrane - bound organelle). The third cell has membrane - bound specialized parts (organelles) which is a characteristic of eukaryotic cells.

Answer:

• First row: Prokaryotic
• Second row: Eukaryotic
• Third row: Eukaryotic
