select all that apply.
all living things are made up of one or more cells.
plant and animal cells have the same shape and structure.
cells carry out the functions needed to support life.
single-celled life can come from nonliving materials.

Explanation:

The core principles of cell theory state that all living organisms are composed of one or more cells, cells are the basic unit of structure and function for life (so they carry out life-sustaining functions), all cells come from pre-existing cells (disproving spontaneous generation), and plant/animal cells have distinct structures (e.g., plant cells have cell walls, chloroplasts).

Answer:

• All living things are made up of one or more cells.
• Cells carry out the functions needed to support life.
