HORTICULTURE

Detailed explanation-1: -Water moves into the roots from the soil by osmosis, due to the low solute potential in the roots (lower s in roots than in soil). This intake o f water in the roots increases p in the root xylem, driving water up.

Detailed explanation-2: -Water in the soil is absorbed by the roots and travels through the stems to the leaves. Water carries nutrients back and forth between roots and leaves. During photosynthesis, plant leaves need water, nutrients and sunlight to make their own food.

Detailed explanation-3: -Transpiration Keeps the Water Moving In plants, water enters the root cells by osmosis and moves into tubes called xylem vessels to be transported to the leaves. Water molecules inside the xylem cells are strongly attracted to each other because of hydrogen bonding (this is called cohesion).
