Question

practice it! select the explanation that best supports why water is essential to all life. water is a polar molecule. this allows water to flow against gravity from roots of plants to leaves. this is vital for photosynthesis. without plants and photosynthesis, there would be no life on earth. water is cohesive. this allows water to flow against gravity from roots of plants to leaves. this is vital for photosynthesis. without plants and photosynthesis, there would be no life on earth. water is not necessary for life on earth. but being cohesive makes it important for plant life.

Explanation:

Water's cohesion allows it to move against gravity in plants, which is crucial for photosynthesis. Photosynthesis is essential for life on Earth as plants produce oxygen and organic compounds. Water is indeed essential for all life. The first option attributes the upward - flow to polarity which is incorrect, and the third option is false as water is essential for all life, not just plant life.

Answer:

Water is cohesive. This allows water to flow against gravity from roots of plants to leaves. This is vital for photosynthesis. Without plants and photosynthesis, there would be no life on Earth.
