The cell membrane maintains the physical integrity of the cell. It's most obvious in the cases of animal cells (because they don't have cell walls) that the cell membrane holds the cell together by enclosing the cytoplasm and organelles within it. The cell membrane forms a barrier between t...

Photosystems are complex arrangements of chlorophyll a with other pigments, including chlorophyll b, xanthophylls and carotenoids, which capture light energy to energize an electron removed from a water molecule. In plants, photosystems are located in the thykaloid membrane within the chloroplast. Two...
