How does soil help plant growth?

Correct answer: By giving nutrients water and support

The direct answer is D: soil gives plants nutrients, water and support. Soil is not merely the surface on which a plant stands. Its spaces can store water and air, and dissolved minerals can be absorbed by roots. Step by step: roots grow through soil; soil holds the roots and keeps the plant upright; water in the soil dissolves minerals; roots absorb water and nutrients; the plant uses them to make food and build tissues. Soil also influences drainage and aeration. D is correct because it includes the three basic services named in the question. A is wrong because colour does not feed or support a plant. B is wrong because soil does not provide sound. C is wrong because some soil or plants may create shade, but shade alone is not the main role of soil. Memory cue: soil is the plant's anchor, water store and nutrient store.
