All algae have
- chlorophyll a and b
- chlorophyll b and carotenoids
- chlorophyll a and carotenoids
- phycobilins and carotenoids
The Correct Option is C
Approach Solution - 1
All algae have chlorophyll a and carotenoids. However, the presence of other pigments like chlorophyll b and phycobilins varies among different groups of algae. Here is the correct combination for all algae:
Chlorophyll a and carotenoids
This combination ensures that all algae can capture light energy for photosynthesis and have protection mechanisms against photodamage.
So, the correct option is (C): Chlorophyll a and carotenoids
Approach Solution -2
Explanation:
- Algae are unicellular organisms which use photosynthesis to get their food.
- All algae have chlorophyll and carotenoids.
- Algae are classified based on their colour; these can be green, blue-green, red, and brown algae.
- Plants and algae which use photosynthesis have chlorophyll A.
- This means that chlorophyll A is a vital component for photosynthesis.
- Chlorophyll A is a green pigment which is found in the majority of plants and algae.
- Green algae contain chloroplasts with chlorophylls a and b but no phycobilins, whereas red algae frequently have chloroplasts with chlorophylls a and c as well as phycobilins.
- Most algae and seaweeds have high carotenoid content.

Notes on Algae
Concepts Used:
Algae
An Algae is a term mentioning a group of photosynthetic eukaryotic organisms. It has chlorophyll and nucleus but no root, stem, leaves and many features like normal land plants. Algae is both unicellular (e.g. Euglenophyta) and multicellular (e.g. seaweeds). Algae do photosynthesis and help in oxygen production
Algae can live in various habitats like moist rocks, soils, water bodies (both freshwater and marine) and in some animals (e.g. Sloth). Unicellular Algae belong to the Protista Kingdom and Multicellular algae belong to the Plantae Kingdom, but formerly all algae are categorized under kingdom Plantae for their photosynthetic nature.
