Melanocytes Cells synthesizing the pigment melanin. These cells are located in deep layers of epidermis and contain branching processes that contact all keratinocytes in basal epidermal layer. The melanin formed in melanosomes are transported to branching processes, shed, and engulfed by keratinocytes.
The collard is a cool season crop that should be grown during early spring or fall. The mature plant will withstand frosts and light to medium freezes. It is one of the most popular garden vegetables in the south and is rapidly becoming a delicacy in northern states as well. Collards provide a good source of vitamins and minerals.
The standard form of a collar is a black leather band around the neck, often with metal D-rings added to allow the attachment of a leash, rope or other restraints; but to be more discreet in public, some people may wear an ordinary choker or jewelry necklace for the same symbolic purpose.
