how does a plant absorb water in the root?
Answers
Answer:
Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption
Explanation:
There are two processes involved in how a plant absorbs water: capillary action and transpiration.
Plants absorb water and nutrients through the xylem: a tissue made up of thin tubes located just below the surface of the plant’s stems. The molecules in this tissue attract water molecules from the soil, so that the water is pulled upwards. This process is called capillary action. It’s similar to what happens when you drink water through a straw.
In the case of plants, it’s solar energy that pulls the water upward. Sunlight evaporates the water on the surface of the foliage leading to a process known as transpiration. Transpiration occurs when this evaporation removes water molecules from the upper surface of the xylem tubes. This creates a vacuum that pulls water upward to fill the gap.
