Step-by-step explanation:
1.each of a large number of elongated microscopic outgrowths from the outer layer of cells in a root, absorbing moisture and nutrients from the soil.
2.Active transport is a type of cellular transport in which substances (e.g. ions, glucose, and amino acids) are transported across a biological membrane towards the region that already contains a lot of such substances. ... The common sites of active transport are root hair cells the wall of small intestine (villi).
3.Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. ... Two major factors influence the rate of water flow from the soil to the roots: the hydraulic conductivity of the soil and the magnitude of the pressure gradient through the soil.
Answer:
1.Ans - A root hair of a vascular plant, is a tubular outgrowth of a hair-forming cell on the epidermis of a plant root. They are lateral extensions of a single cell, and invisible to the naked eye and light microscope. The function of root hairs is to collect water and mineral nutrients from the soil.
2.Ans - Active transport is the process of moving molecules across a cellular membrane through the use of cellular energy. ... Active transport involves molecules moving against a gradient or other form of resistance, such as from an area of lower to higher charge.
Example : lons moving from soil into plant roots.
.3.ans - Transpiration is a process by which water is transported through a plant from it's roots to tiny pores on the underside of it's leaves where it evaporates into the atmosphere by changing into water vapour. Transpiration is, in essence, the evaporation of water from the leaves of plants.
