A. Solid state
B. Liquid state
C. Ionic state
D. Gaseous state
Answer: Option A
Solution(By Examveda Team)
The root can absorb minerals from the soil when they are in a Solid state.In plants, the entrance portal for mineral uptake is usually through the roots. Some mineral ions diffuse in between the cells.
Plants absorb minerals in the ionic form: of nitrate (NO3-), phosphate (HPO4-), and potassium ions (K+); all have difficulty crossing a charged plasma membrane.
Mineral nutrient concentration in roots maybe 10,000 times more than in surrounding soil. During transport throughout a plant, minerals can exit the xylem and enter cells that require them.
