Ans 1.

Caretenoids are the organic pigments which are produced by several plants , algae , bacteria and fungi.

They help to absorb light energy useful for photosynthesis and also protect the chlorophyll from photodamage.

Examples of Caretenoids are lycopene , vitamin A precursor beta carotene , lutein , staphyloxanthin etc.
