Describe the photoactivation of chlorophyll
WebChlorophyll is a green pigment that acts as a photoreceptor. It is a pigment that absorbs light energy and aids in the photosynthesis. Chlorophyll exists in many forms, such as chlorophyll a, chlorophyll b, etc. The chlorophyll absorbs light energy of red and blue wavelengths. Whereas, the green light is not absorbed and is reflected back. WebThe effect of the presence or absence of chlorophyll on photosynthesis can be investigated using a variegated plant. Variegated plants have regions of their leaves with, and …
