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.
Collards are high in calcium, vitamin C, and fiber. The stems of collards are edible, but take longer to cook than the leaves. The stems are often removed. Adding a acidic seasoning like vinegar or lemon helps reduce the bitterness and give collard greens a great flavor.
