Yes roots roots do both,root hairs absorb minerals dissolved in water .Water uptake from the soil by root cells is passive, and also follows osmotic gradients caused by the mineral nutrients
Salts are absorbed by the roots.
Plants extract the needed salts from soils.
Many plants require roots. Basically, the roots are required to absorb water & mineral salts. The roots, being long & narrow will absorb water and mineral salts as they grow between the soil particles rich in these raw materials. This is why, the roots of a balsam plant are important.
in hydroponics,the roots of plants are immersed in solutions containing dissolved mineral salts.
All the plants need fertilizers which are salts.
By osmosis
By the intermediate of roots.
Plants absorb mineral nutrients by way of ions in the soil. This is basically the case with how all plants get their nutrients besides sunlight. The process takes place at the atomic level.
sunlight, water, mineral salts from the soil, and carbon-dioxide from the air.
Plants most of the time have roots in the soil. These roots have root hairs and get mineral/salts + water from the soil. The xylem/phloem tubes in the plant transport these mineral/salts + water to different places of the plant. So simply said: Plant get their food from the soil. And so it also depends if your soil is well fertilised etc.
it does not
Take in water and mineral salts for the plant
