1. Bacterial cell structure: cell wall, membrane, cytoplasm. 2. Bacteria reproduce by binary fission. 3. Viruses classified by genetic material. 4. Economic importance of viruses in vaccines. 5. Algae characteristics: photosynthetic, aquatic. 6. Algae habitats: freshwater, marine, terrestrial. 7. Fungi characteristics: chitin cell walls, absorb nutrients.

["1. Structure of bacterial cell: Bacterial cells have various shapes including cocci, rods, and spirals. They consist of a cell wall, cell membrane, cytoplasm, ribosomes, and genetic material without a nuclear membrane.","2. Reproduction of bacteria: Bacteria reproduce mainly through binary fission, a process where a single cell divides into two identical daughter cells.","3. Classification of viruses: Viruses are classified based on their nucleic acid type (DNA or RNA), their replication method, morphology, and host organisms.","4. Economic importance of viruses and vaccine production: Viruses play a role in biotechnology and medicine, such as in the development of vaccines which are crucial for preventing viral diseases.","5. General characteristics of algae: Algae are photosynthetic organisms, often found in aquatic environments, and can range from single-celled to multicellular forms.","6. Types of algae habitats: Algae can inhabit various environments, including freshwater, marine, and terrestrial ecosystems.","7. Basic characteristics of fungi: Fungi are non-photosynthetic organisms with cell walls made of chitin, obtaining nutrients through absorption, and can reproduce sexually and asexually."]
