WebStructure. The root hair cell is roughly rectangular in shape with a cytoplasmic extension on its lateral end (the root hair). It has the following cellular components: A cell wall with intercellular spaces. A semi-permeable cell membrane. A large central vacuous for maximum water and salt retention. A cornered nucleus. WebSolution. Verified by Toppr. Water passes from the soil to the root hair cell’s cytoplasm by osmosis. This happens because the water in the soil has a higher water potential than the root hair cell cytoplasm. Root hair cells have a large surface area for absorption of water and to speed up osmosis.
