Answer 1

The statement that is true about cells is:

Cells are the most basic unit of life.

The other statements are not accurate:

• Cells are found in both single-celled organisms (like bacteria) and multicellular organisms (like plants and animals).
• Not all cells have a nucleus; prokaryotic cells (like bacteria) do not have a nucleus.
• Not all cells have internal organelles surrounded by membranes; for instance, prokaryotic cells typically lack membrane-bound organelles.
