Hint: Chlorophyceae is a vast and very important class of thallophyta containing different types of algae. They are grouped primarily based on the types of photosynthetic pigments present in them. Most of the members of thallophyta are freshwater algae.
Complete answer: All green algae are characterized by the presence of photosynthetic pigments- chlorophyll a and chlorophyll b, and it is the presence of these two specific pigments that make them appear green in color.
Along with these pigments they also contain some accessory pigments namely, beta carotene (red-orange) and xanthophylls (yellow) located in stacked organelle i.e. the thylakoids.
The cell walls of green algae are cellulosic, and they store carbohydrates in the form of starch. Ulothrix, Spirogyra, Cladophora, Ulva, Chara essentially belong to the class Chlorophyceae.
So, the correct answer is option B. Ulothrix, Spirogyra, Cladophora, Ulva, Chara.
Note: Oceans contain the greatest number of green algae, which is the reason why they are the staple food source for many marine creatures.
Green algae are important both ecologically and scientifically as they are major producers and are responsible for half of the oxygen production in the world.
