Why do dried fruits and vegetables slowly swell when placed in water?

What occurs when dried fruits are swollen in water?

Why does the grass in a lawn that has been fertilized die when it doesn’t rain think of osmosis?

Answer Expert Verified. he reason for this is the fertilizer must be dissolved in water so the plant’s roots can ingest it.

What happens if you over fertilize grass osmosis?

When you add too much fertilizer to the soil plants cannot take up water. Plants rely on an osmotic pressure gradient in order to collect water. This is where the term burning your plants comes from. The water is flowing from the leaves out the roots and the leaves burn because they don’t have water to cool them.

What will happen if dried vegetables kept in water?

The dried vegetables have less water content and high salt concentration in cells. When they are kept in water they absorb water and become fresh.

Why water moves out of the mango pieces when they are immersed in a 65 sugar solution?

Mangoes can be dried to enable them to be stored for long periods of time. The pieces of mango are immersed in a concentrated sugar solution. Water moves out of the mango cells by osmosis. This method of drying does not expose the mangoes to such high temperatures as sun drying.

What happens to fruits and vegetables when they are dried?

If the food is dried at a temperature that is too high, the outer surface will harden, preventing moisture from escaping from the center of the slice—this is called case hardening. Food shrinks when it is dried, so use a fine mesh for smaller fruits and vegetables.
