What is function of carotene in photosynthesis?

Answer 1

Carotene is closely allied to chlorophyll in plants and organisms that undergo photosynthesis. It serves two roles. First it absorbs some of the sunlight that is missed by the chlorophyll molecules. Secondly, because of its high number of reactive double bonds, it makes a good 'sponge' to react with, and therefore 'mop up', energetic oxygen molecules that might otherwise oxidise and degrade more important parts of the plant structure. In a typical leaf, there is a ratio of chlorophyll to carotenoid of about 1:3, and the darker the leaf the more carotenoids it contains. Normally, however, the green colour of chlorophyll is so intense it masks the more subtle Oranges and reds of the carotenoids. In Autumn however, when the chlorophyll decays, the green fades and leaves turn red and yellow.

Answer 2

Carotene are synthesized by plants They are responsible for the orange color vegetables and fruits like carrots. The Beta-carotene have antioxidant properties. They are a rich source of vitamin A. This is necessary for proper functioning of the immune system and for normal growth.

Answer 3

Carotene is a pigment that absorbs light energy and transfers it to chlorophyll molecules in photosynthesis. It helps broaden the range of light wavelengths that can be absorbed by plants, increasing the efficiency of photosynthesis.

Answer 4

Carotenoids are pigments and they are chemicals with nutritive properties.
