You are thinking of Melanocytes. Which contain and create the melanin. The melanin is the pigment which then makes them appear dark.
Pigment
Plant cells that contain the green pigment chlorophyll also appear green in color. This green pigment is contained within the chloroplast.
This is called Melanocytes
The green coloring or pigment in plant is called CHLOROPHYLL. carentoniod anthocyanins betalains
Chlorophyll is the green pigment in plants. Chlorophyll is found in cyanobacteria and it is found in the chloroplasts of plants and algae.
Chloroplasts contain chlorophyll. Chlorophyll is a green pigment that absorbs light energy for photosynthesis. Chloroplast are not found in all plant cells.
Pigment
Melanocytes produces melanin, the skin pigment that absorbs UV light from the sun and prevents it from damaging DNA in the cells.
Plant cells that contain the green pigment chlorophyll also appear green in color. This green pigment is contained within the chloroplast.
its called hemoglobin. it is the pigment which carries oxygen in blood
black absorbs the sunlight which capture solar cells used for electricity
Chloroplasts are in palisade cells in plants, and contain the green pigment chlorophyll. Chlorophyll is what actually absorbs the sunlight needed for photosynthesis.
Chlorophyll
This is called Melanocytes
Green, the reason chlorophyll is known as a green pigment is because it absorbs all wavelengths of light but reflects green light.
The green coloring or pigment in plant is called CHLOROPHYLL. carentoniod anthocyanins betalains
Pigment is a substance that absorbs some wavelengths of lights and reflects other, giving something its color. Chlorophyll is the green substance that absorbs light and provide energy for photosynthesis.
