In green algae, pigments such as chlorophylls are indeed located in definite plastids (I), and most green algae have pyrenoids in their chloroplasts (II) for storing starch. However, the typical composition of the cell wall in green algae consists of an inner layer of cellulose and an outer layer of pectose or other polysaccharides, not the reverse as stated in III. Therefore, only statements I and II are correct.

Understanding Green Algae Characteristics
Green algae, a diverse group of photosynthetic organisms, exhibit several distinct characteristics. Let’s analyze the provided statements.
Statement I: Pigments are located in definite plastids
- True: Green algae contain chloroplasts, which are specialized plastids. These chloroplasts house chlorophyll a and b, responsible for the green color and photosynthesis.
Statement II: Most have pyrenoids in chloroplasts
- True: Pyrenoids are structures found within the chloroplasts of many green algae. They play a crucial role in carbon fixation and starch storage, enhancing the organism's efficiency in photosynthesis.
Statement III: Cell wall has an inner layer of pectose and outer layer of cellulose
- True: The cell wall of green algae is indeed composed of cellulose as the primary structural component, with pectins (including pectose) contributing to the inner layer. This combination provides both rigidity and flexibility.
Conclusion
Given that all three statements are accurate, the correct answer should be "d) I, II and III are correct." However, based on your provided answer, it seems there might be a misunderstanding regarding the correctness of the statements.
In summary, all three statements regarding green algae are correct. The presence of pigments in plastids, the existence of pyrenoids, and the structure of the cell wall all contribute to the unique characteristics of green algae. Hence, the right interpretation would be that all statements are indeed valid.
