900 nm), comprising about 30% of the incoming solar energy. The light that is absorbed the best is blue, so this shows the highest rate of photosynthesis, after which comes red light. In plants, photosynthesis occurs in the chloroplasts of the plant cells. The relative absence of freshwater brown algae does not seem to be related to their photosynthetic light use. Photosynthesis takes place through several steps which occur during two stages: the light phase and the dark phase. Do you know a little more? Plants who can make their own food are known as autotrophs.But, there are few plants who cannot and are called as heterotrophs.The process by which plants make their own food is called as photosynthesis.The photosynthesis process occurs largely in the leaves of the plant which are known as the ‘kitchen of the plant’. Photosynthesis is the process of capturing light energy and transforming it into chemical energy. The second part of photosynthesis, the so called DARK reactions (Calvin-cycle) occur in the absence of light. Photosynthesis would not occur in the absence of Select one: a. oxygen and water. This would mean that the purple sulphur bacteria can use H2S as a hydrogen donor, but cannot use H2O. The fruit pericarp is not the only non‐foliar green tissue that is capable of photosynthesis. molecular oxygen.
