13. The Sunlight Good for Plants and Animals. 



Although plants cannot move about the same as 

 animals, they do turn their leaves toward the sun and 

 even grow in the direction of the sunlight. Look at the 

 plants which are near the window in the room, and notice 

 how they lean toward the sunlight. This shows that the 

 sunlight is good for plants. If there were no sunlight 

 most of the plants would soon die. 



The sunlight is also good for animals and man. If 

 a person stays indoors too much he will become sickly. 

 We should be out in the sunlight as much as possible, 

 and our buildings and houses should have many win- 

 dows so that the sunlight can enter freely. The sun has 

 a stimulating effect upon the body, and often persons 

 take sunbaths to improve their general health. Taking 

 a sunbath usually means sitting in the sunshine, but in 

 hospitals they are given by having the patients lie on 

 cots, being covered only by a sheet.
