Description: Embedded video lesson on first slide! Then students answer 31 questions. This lesson explores natural pigments, their sources, and uses. Natural pigments are obtained from plants or minerals and can be used in paints, food coloring, and art. Plant pigments like chlorophylls, anthocyanins, betalains, and carotenoids determine plant colors and can be separated through chromatography. Chlorophyll is responsible for green plant color and plays a key role in photosynthesis. Photosynthesis converts light energy into chemical energy using chlorophyll, water, sunlight, and carbon dioxide. Chlorophyll has therapeutic properties and aids in detoxification. Natural pigments can be extracted from plants through boiling and water extraction. Earth pigments from minerals are used for dyes and paints. Pigments contribute to the appearance of organisms and the human body, with melanin affecting hair and skin color.
