The cells that produce the pigment in hair are called melanocytes.
Pigment cells (melanocytes) are found in the basal layer of the epidermis.
Regular blood cells contain respiratoy pigment in them.
Reg blood cells contains the respiratoy pigment haemoglobin.
Pigment cells (melanocytes) are found in the basal layer of the epidermis.
the green pigment in plants is chlorophyll.
A birthmark is formed during fetal development when skin cells grow abnormally or when blood vessels cluster together. They can be classified into two main types: pigmented birthmarks, which are caused by an excess of pigment cells, and vascular birthmarks, which result from abnormal blood vessel formations. The exact cause of why some birthmarks develop is not fully understood, but genetic and environmental factors may play a role. Most birthmarks are harmless and may fade or change over time.
Hemoglobin
Chlorophyll
the palisade cell contains chloroplasts which in turn contain chlorophyll the photosynthetic pigment within plant cells.
Melanocytes are the pigment-producing cells in the epidermis. They are responsible for producing melanin, the pigment that gives skin its color and helps protect it from the damaging effects of UV radiation.
A birthmark is a normal variation of the skin (usually caused either by an unusual concentration of melanocytes - pigmentation cells - or minor anomalies in small blood vessels), and is, therefore, very much alive!
