Question

what is the most important role that water plays for living organisms?

all organisms need water to transport chemicals into their cells.

all organisms need water as an energy source.

all organisms live in the water.

Explanation:

• Water is a universal solvent, enabling transport of nutrients, gases, and waste across cell membranes, which is essential for all living organisms' basic functions.
• Water is not an energy source (organisms use molecules like glucose for energy).
• Staying clean is not a core biological requirement for all organisms related to water's critical role.
• Many organisms (e.g., terrestrial plants and animals) do not live in water.

Answer:

A. All organisms need water to transport chemicals into their cells.
