Detailed explanation-1: -Plant roots generally absorb nutrients from the soil when they absorb water as the nutrients remain dissolved in it. They mainly uptake the nutrients by the diffusion process. Also, they get oxygen from the air through leaves.

Detailed explanation-2: -Diffusion operates by these highly concentrated ions moving as far away from one another as possible, and becoming exposed and available to the plant roots. Phosphate, potassium and zinc are the main nutrient ions moving as a result of diffusion.

Detailed explanation-3: -Water from the soil is absorbed by the roots through a process known as osmosis. The cell membrane of the root hair cells acts as a semi-permeable membrane.

Detailed explanation-4: -Mineral nutrients come from the soil. These nutrients are absorbed by the plants roots when uptaking water. Mineral nutrients are broken up into macronutrients and micronutrients. The most important primary macronutrients for plants are nitrogen (N), phosphorus (P), and potassium (K).

Detailed explanation-5: -Although all green plants make their food by photosynthesis, they also need to get nutrients from the soil. These dissolve in water and are taken up by the roots of the plant. The most important plant nutrients are nitrogen (N), phosphorous (P), and potassium (K).
