1 WORKBOOK Biology Subject: Teacher: Iva Kubištová Student:.. School year:../ This material was prepared with using Topics: Viruses and Bacteria

2 Viruses and Bacteria - Task No 1: Repetition of Viruses and Bacteria. Answer next questions. Use a vocabulary. 1. Describe the structure of a virus. Why virus is non living organisms? 2. Explain how viruses cause infection. 3. Explain how the two groups of prokaryotes differ. 4. List the parts of bacterial cell. 5. What are some ways that prokaryotes obtain energy? What do you know about nutrition of bacteria? 6. Give some examples of diseases caused by viruses and bacteria. 7. Give some examples of benefits bacteria for human and other organisms. 8. Explain what is commensalisms, mutualism, parasitism. Vocabulary: 1. Virus, bacteriophage, protein capsid,,dna, RNA, head, tail apparatus, cannot move, cannot replicate, cannot make proteins 2. Lytic infection, lysogenic infection, host cell, many copies, NA integrates into chromosome,provirus replicated 3. Strong cell walls, contain peptidoglycan, extreme kinds of environment, Archea, Eubacteria. 4. Capsule, cell wall, cytoplasmatic membrane, cytoplasm, ribosomes, nucleoid, flagella, pilli. 5. Chemoautotroph, photoautotroph, heterotroph. Oligate aerobe, obligate anaerobe, facultative anaerobe. 6. Sexually transmited diseases, respiratory deseases, digestive tract deseases. 7. Nitrogen fixation, yogurt 8. Symbiotic organisms, benefit, harmful organism, host cell, benefit without harming. Viruses and Bacteria - Task No 2: Lytic cycle. Write correct sequence of A-E. A. New viruses are made from the proteins and DNA. B. The cell s DNA is destroyed. The cell then makes new viral DNA and proteins. C. The virus attaches to the cell. D. DNA from the virus enters the cell. E. The cell breaks open and viruses are released

3 Viruses and Bacteria - Task No 3: Three Domains System. Read the evolutionary tree. Mark sentences below which are in context with scheme of evolution. 1. Viruses cannot make proteins. 2. Many viruses cannot be transmitted between different species. 3. Bacteria are many in numbers and forms. 4. Bacteria are tiny (beyond our vision) but their biomass outweighs all eukaryotes tenfold. 5. Bacteria are rapidly growing and reproducing. 6. Bacteria are almost everywhere (ubiquity). 7. Some foods are made with the aid of bacteria. 8. Bacteria are motile and/or easily transported. 9. Bacteria have high diversity. 10. Bacteria can live everywhere. They can use mutualisms, commensalism and parasitism. 11. Bacteria can live without us but we cannot without them. 12. Viruses are a nonliving strand of genetic material within a protein coat.

4 Viruses and Bacteria - Task No 4: Nutrition of Bacteria. Insert right words: PARASITISMS, COMMENSALISM, and MUTUALISM one organism is receiving benefit without harming the other one organisms benefits at the expense of the host both symbiotic organisms benefit Viruses and Bacteria - Task No 5: Mode of nutrition of Bacteria. Complete the tables. Mode of nutrition Energy source Carbon source AUTOTROPH Photoautotroph CO 2 Chemoautotroph Inorganic chemicals HETEROTROPH Photoheterotroph Organic compounds Chemoheterotroph Organic compounds

5 Viruses and Bacteria - Task No 6: Structure of Virus and Bacteria. Fill in right names of parts of microorganism (NA, enzyme, capsid, protein; chromosom pilli, plasmid, flagella, capsule, ribosomes, plasma membrane, and cell wall) upraveno dle:

6 Viruses and Bacteria - Task No 7: Diseases. Complete table. English name Czech name Viral/bacterial AIDS Viral Typhoid (camp) fever Bacterial Spalničky Mumps Neštovice Gastric ulcers Bradavice Common cold, influenza Gastroenteritis Plague, pest, bubonic plague Cholera Respiratory inflammations Borelióza Obrna Tetanus Rabies Diphtheria Žloutenka
