why do roots absorb water Root hair cells are adapted for the efficient uptake of water by osmosis and mineral ions by active transport They contain mitochondria which release energy for active transport
Absorption of water in plants is a biological process in which the plants uptake capillary water from the soil to the root xylem through the root hairs during various plant processes like respiration transpiration and osmosis This mechanism of absorption of water is sometimes referred to as passive absorption because the entry of water into the roots is brought about probably by conditions which originate in the

Water s importance to plants stems from its central role in growth and photosynthesis and the distribution of organic and inorganic molecules Despite this dependence plants retain less Particles of water are absorbed by osmosis a type of diffusion into plant root hair cells Nitrate ions are absorbed into plant root hair cells by active transport which requires energy Root
While the transport of water is usually unidirectional in xylem upward or lateral the movement of sugars in the phloem is multi directional and occurs by active transport an energy dependent Bio libretexts app auth 3 login returnto s 3A 2F 2Fbio libretexts 2FBookshelves 2FIntroductory and General Biology 2FIntroductory Biology CK 12 2F09 253A Plants 2F9 14 253A Roots

The absorption of water is chiefly via osmosis which occurs because 1 water is present in higher concentrations in the soil than within the epidermal cells where it contains salts sugars and other dissolved organic They are also responsible for absorbing water and mineral ions like nitrates from the soil Roots have specialised cells called root hair cells These have long thin projections that stick out into the soil This massively increases the surface
In the case of soil moisture the roots will passively absorb water that is present in the soil This water is known as capillary water which is the moisture that remains after gravitational water has been drained The more moisture within Plants absorb water from the soil through their roots Plant roots have tiny hairs on them so they can absorb as much water as possible
