Question

Explain why diffusion is helpful for aquatic plants and animals

Answer 1

Answer:

It's only because of diffusion so that the aquatic animals can survive. It's because oxygen is present in water due to diffusion and that why aquatic animals can breathe under water.

Mineral uptake - Useful minerals and ions need to be taken up from soil into plants via root hair cells. These cells are adapted (through a large surface area and large number) to maximise the rate of diffusion. Therefore, the useful molecules in the soil move down a concentration gradient and into the roots to be taken up by the plant. Many molecules found in the soil are essential for the growth and survival of plants, making diffusion a very important process.
