From the soil through the roots of the plant:
Plants absorb water from the soil through their roots in a process known as transpiration. This water is then transported through the plant to the leaves where photosynthesis takes place.
Roots:
- The roots of a plant have tiny root hairs that increase the surface area for water absorption.
- These root hairs absorb water and essential nutrients from the soil.
Xylem:
- The water absorbed by the roots is transported through a network of tubes called xylem.
- Xylem vessels run throughout the plant, delivering water and nutrients to the leaves.
Stomata:
- Once water reaches the leaves, it is used in photosynthesis.
- The majority of the water needed for photosynthesis is drawn up through the plant from the soil and is not directly taken from the air.
Therefore, most of the water needed for photosynthesis comes from the soil through the roots of the plant. This water is crucial for the plant's survival and is essential for the process of photosynthesis to occur.
