WebThe outer surfaces of the thylakoids and the lamellae connecting the thylakoids are also called the photosynthetic membrane. This membrane contains the pigment molecules of chlorophyll and carotenoid. These solar collector pigments act like antennae to capture the solar energy and start the carbohydrate making process we call photosynthesis. WebMolecules that freely cross cell membranes do so through the process of simple diffusion. That is, they move from a high concentration outside the cell to a lower concentration inside the cell, or vice versa.
