1.When dry raisins are placed in water, they swell up. It happens because the water from the surrounding diffuses into the raisins resulting into swelling of them. This process is called osmosis. If these raisins are placed in a concentrated salt solution, they will shrink due to osmosis.

2.When seeds are soaked in water, they begin to warm up and produce carbon dioxide. ... Seeds are dormant, or at least close to dormancy. When we provide them with warmth and moisture they start to grow.

3.Epithelial Cells

Epithelial CellsThe tissue that lines the inside of the mouth is known as the basal mucosa and is composed of squamous epithelial cells. These structures, commonly thought of as cheek cells, divide approximately every 24 hours and are constantly shed from the body.
