Above is a diagram of a section through part of a young root.

(a) Describe the pathways by which water passes from the soil to the cells of
the cortex shown in the diagram.

The diagram shows the location where mineral ions in the soil enter the plant. There is a greater density of mitochondria in cell X than in a cell of the
root cortex.

(b) With reference to the uptake and transport of mineral ions, suggest why there is a greater density of mitochondria in cell X than in a cell of the root cortex.

a)Passes from the water film surrounding soil particles through the cell wall by diffusion and then through the vacuole by osmosis. From here water can both pass to the other cortex cells by osmosis or pass through the tiny gaps between cells viadiffusion

b) Because there is a high concentration of mineral ions in the soil than the cell X more mitochondria is needed to supply energy for active transport against the concentration gradient.In the cell of the cortex however active transport happens in lesser rates because most ions would've passed from the root hair cell ( cell x)itself

hope this helps, btw it would be really appreciated if this is marked as brainliest

Cheers!
