[0002] Cottonseed is the seed of cotton crops. The cotton taken from the cotton boll is called seed cotton, and the cotton fiber rolled off the seed cotton is called lint cotton. After the lint is removed from the seed cotton, cottonseed can be obtained. The outside of the cottonseed is a hard brown seed shell, and the shape and size vary depending on the variety.
