How do diffrent Parts of the Plants get water
Answers
Answer:
Different parts of the plant get water through a process called osmosis.
Explanation:
Plants absorb water through their entire surface – roots, stems, and leaves. However, the majority of water is absorbed by root hairs. Root hairs are thin-walled uni-cellular outgrowths of the epidermis. They are in close contact with the thin film of water surrounding the soil particles.
The cell wall of the root hair is permeable to water and minerals, but its cell membrane and the membrane around the vacuole from semi-permeable membranes. Soil solution is a weaker solution as compared to the cell sap of root hair. Because of this osmosis occurs and the water is absorbed by the root hairs through cell membranes from the soil. Then the root hair cells become more turgid and their osmotic pressure falls. The cells of the cortex have higher osmotic pressure which causes the diffusion of water from the root hair to cortical cells.
