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 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. 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.

Explanation:

Brief Explanations
  • First cell description:
  • Eukaryotic cells have a nucleus and membrane - bound organelles (like chloroplasts in plant cells). Since the cell is part of a plant's stem (a complex multicellular plant structure, and plants are eukaryotic) and has DNA in a nucleus and membrane - bound organelles, it is eukaryotic.
  • Second cell description:
  • The presence of specialized membrane - bound parts (organelles) that perform functions like energy production (e.g., mitochondria), digestion (e.g., lysosomes in some cells), and movement (e.g., cilia - related structures in some eukaryotic cells) is a characteristic of eukaryotic cells.
  • Third cell description:
  • Prokaryotic cells have their DNA floating freely in the cytoplasm (no nucleus). Also, prokaryotes can have diverse ways of getting energy (like using sulfur as in some extremophile bacteria).

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.
