Science Daily: Scientists witness living plant cells generate cellulose and form cell walls
In a groundbreaking study on the synthesis of cellulose -- a major constituent of all plant cell walls -- a team has captured images of the microscopic process of cell-wall building continuously over ...
Diagnosis If you have trouble seeing certain colors, an eye care professional can test for a color deficiency. Testing likely involves a thorough eye exam and looking at specially designed pictures.
