CBSE Class 11 — Subject: Biology

30:00

Questions: 30 | Duration: 30 minutes

1. Tobacco mosaic virus (TMV) causes mosaic patterns on leaves of infected plants. TMV is an example of a:

Bacterial disease Plant viral disease Fungal infection Nematode infestation

2. Which animal disease is caused by a virus transmitted through saliva and causes fatal encephalitis?

Rabies Tuberculosis Ringworm Malaria

3. The virus causing influenza primarily infects which system in humans?

Digestive system Nervous system Respiratory system Circulatory system

4. Which of the following is a plant virus transmitted by insect vectors (e.g., aphids)?

Influenza virus Potato virus Y (PVY) HIV Hepatitis B virus

5. Which viral disease affects humans and is characterised by fever, rash, and Koplik's spots?

Common cold Rabies Tuberculosis Measles

6. Plant viral infections are often controlled by:

Controlling insect vectors and using virus-free planting material Antibiotic sprays Antifungal fungicides Flooding fields

7. Which virus causes chickenpox and later may reactivate as shingles?

Hepatitis virus Varicella-zoster virus (VZV) Influenza virus TMV

8. Foot-and-mouth disease primarily affects which animals?

Fish Birds only Cloven-hoofed animals like cattle, sheep and pigs Reptiles

9. The human immunodeficiency virus (HIV) primarily attacks which cells?

CD4+ T lymphocytes (helper T cells) Red blood cells Hepatocytes Neurons

10. Which vaccine is used to prevent poliomyelitis (polio)?

BCG vaccine Measles vaccine Rabies vaccine Oral polio vaccine (OPV) / Inactivated polio vaccine (IPV)

11. Which viral disease is vector-borne and transmitted by Aedes mosquitoes, causing high fever and severe joint pain?

Influenza Dengue Measles Polio

12. Plant viruses often have which type of nucleic acid?

Single-stranded RNA (e.g., TMV) Double-stranded DNA always Proteins only Lipids only

13. Which animal viral disease is prevented by the DPT (Diphtheria-Pertussis-Tetanus) vaccine?

Measles Polio Rabies None of the above (DPT does not include viral diseases)

14. The mosaic symptom in plants is due to:

Fungal toxin only Viral infection causing discolouration and patchy chlorosis Bacterial exudate Nutrient deficiency alone

15. Which animal virus causes severe liver inflammation and can be prevented by vaccination (Hepatitis B)?

Hepatitis B virus (HBV) HIV TMV Potato virus Y

16. Which of the following is NOT a mode of transmission for plant viruses?

Through insect vectors Through mechanical sap transfer Airborne respiratory droplets (typical of animal viruses) Through infected seeds or tubers

17. Which viral disease of animals is viral hemorrhagic fever transmitted by rodents in some regions?

Measles Hantavirus infections TMV Polio

18. Which plant disease is associated with dwarfing and leaf curl symptoms, often transmitted by whiteflies?

Begomovirus infections (e.g., Tomato yellow leaf curl virus) Influenza infection in plants Rabies in plants Measles in plants

19. Which method is commonly used for diagnosis of many animal viral infections in the laboratory?

Gram staining Serological tests and PCR Soil culture Taste test

20. Which of these is a plant disease caused by a DNA virus?

TMV (RNA virus) PVY (RNA virus) Cauliflower mosaic virus (CaMV) — a DNA virus Influenza (animal RNA virus)

21. Which vaccination strategy provides passive immunity immediately after exposure?

Administration of antiserum (passive immunization) Live attenuated vaccine given months earlier Antibiotic prophylaxis Using insecticides only

22. Which of the following animal viruses is a retrovirus?

Influenza virus HIV (Human Immunodeficiency Virus) TMV Cauliflower mosaic virus

23. Which animal viral disease is preventable by the BCG vaccine?

Polio Measles None — BCG is for tuberculosis (a bacterial disease) Rabies

24. Which control measure reduces spread of insect-transmitted plant viruses?

Vector control (insect management) and use of resistant varieties Antibiotic seed treatment Increasing soil salinity Adding viral cultures to soil

25. Yellow fever, a serious viral disease, is transmitted by which vector?

Ticks only Aedes mosquitoes Aphids Direct contact only

26. Which of the following is TRUE about viral diseases in plants compared to animals?

Plant viruses can be treated with antiviral drugs effectively Plant viruses are often spread by vectors and require management of vectors and propagation material Animal viruses never use insect vectors Plant viruses replicate in animal cells

27. Which diagnostic technique can detect plant viruses by identifying viral RNA or DNA?

Gram staining ELISA only PCR (Polymerase Chain Reaction) to detect viral nucleic acids Taste testing

28. Which of the following is a feature of many animal viral diseases but not of plant viral diseases?

Transmission by respiratory droplets and human-to-human spread Transmission only by insect vectors Infection confined to roots only Plant-to-human virus transmission common

29. Which zoonotic virus caused global concern originating from bats and civets and led to outbreaks of severe acute respiratory syndrome?

TMV SARS coronavirus (SARS-CoV) Begomovirus Potato virus Y

30. Overall, preventing viral diseases in plants and animals most effectively relies on:

Only using antibiotics Allowing uncontrolled vector spread Sanitation, vector control, vaccination (where available) and use of disease-free planting material Ignoring quarantine measures
