WebChlorophyll a absorbs light within the violet, blue and red wavelengths. Accessory photosynthetic pigments broaden the spectrum of light absorbed, increasing the range of wavelengths that can be used in photosynthesis. [5] The addition of chlorophyll b next to chlorophyll a extends the absorption spectrum.
Web1 day ago · A trend that has been circulating for some time on TikTok is that chlorophyll, extracted from plants, has near-magical properties. Acne, bloating, and body odour disappear, replaced with flat stomachs and clear skin.
