Question

practice it! select the explanation that best supports why water is essential to all life. water is not necessary for life on earth. but being cohesive makes it important for plant life. 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 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.

Explanation:

Water's cohesion allows it to flow against gravity in plants, which is crucial for photosynthesis. Photosynthesis by plants is fundamental for life on Earth as it produces oxygen and organic compounds. The first statement is incorrect as water is essential for life. The polarity of water is not the main reason for its upward - flow in plants for photosynthesis; cohesion is.

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.
