Algae: Diversity, Structure, and Reproduction

Here are some important questions related to "Algae: Diversity, Structure, and Reproduction" suitable for BSc level:

Diversity:

1. Classify algae into major groups (Cyanophyta, Chlorophyta, Phaeophyta, Rhodophyta) and describe their characteristics.
2. Describe the differences between green, brown, and red algae.
3. What are the unique features of dinoflagellates and diatoms?
4. Compare and contrast freshwater and marine algae.

Structure:

1. Describe the cell structure of Chlamydomonas (green algae) and Nostoc (cyanobacteria).
2. Explain the organization of thallus in brown algae (e.g., Fucus).
3. Compare the cell walls of green, brown, and red algae.
4. Describe the structure and function of pyrenoids in algae.

Reproduction:

1. Explain the life cycle of Chlamydomonas (haplontic) and Ulva (diplo-haplontic).
2. Describe the methods of vegetative reproduction in algae (e.g., fragmentation, budding).
3. Compare sexual reproduction in green (e.g., Chlamydomonas) and red algae (e.g., Polysiphonia).
4. Explain the process of sporogenesis in brown algae (e.g., Fucus).

Additional Questions:

1. What are the economic importance and uses of algae?
2. Describe the role of algae in aquatic ecosystems.
3. Explain the process of photosynthesis in algae.
4. Compare the adaptations of algae to different environments (e.g., freshwater, marine, terrestrial).

Long Answer Questions:

1. Describe the diversity of algae, highlighting their classification, structure, and reproduction.
2. Explain the life cycle and reproductive strategies of a selected algal group (e.g., green algae, brown algae).
3. Compare and contrast the structure and function of different algal cell components (e.g., cell walls, chloroplasts).

Short Answer Questions:

1. Define: Thallus, Pyrenoid, Sporogenesis.
2. Describe the differences between: Green algae and Cyanobacteria, Brown algae and Red algae.
3. Explain: Vegetative reproduction in algae, Sexual reproduction in green algae.
