• Question: If photosynthesis occurs in plants that are green, what happens in other coloured plants- how do they make their own food? For example the Japanese Maple has red leaves which means they do not contain chlorophyll.

      Hi 12sarsat
      Almost all plants have chlorophyll. In the Japanese Maple and other plants with coloured leaves chlorophyll is just masked by other pigments – anthocyanins which are red and purple mainly, and carotenoids which are yellowy orange.
      There are some plants, called parasitic plants that don’t have chlorophyll and survive by living off other plants.

      Some plants have adapted different mechansims for their photosynthesis. They have different pigments that can absorb green light (so that they don’t reflect green and therfore don’t look green). Some plants also have much higher leaves of other pigments (not for photosynthesis but for some other function) that masks the chlorophyll.
