Assertion : Eubacteria have an outer cell wall. Reason : Archaebacteria lack any cell wall like structure.
1 Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
2 Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
3 Assertion is true but Reason is false.
4 Both Assertion and Reason are false.
Explanation:
Cell wall of eubacteria is composed of carbohydrate – protein complex and peptidoglycan. Cell wall of archaebacteria lacks peptidoglycan.

Under unfavourable conditions, bacteria reproduce by
1 Fission
2 Plasmodium
3 Budding
4 Production of spore
Explanation:
Under unfavourable condition, bacteria are reproduced by Spore.

Select the mismatch :
1 Rhodospirillum - Mycorrhiza
2 Anabaena - Nitrogen fixer
3 Rhizobium - Alfalfa
4 Frankia - Alnus
Explanation:
Rhodospirillum is a gram negative bacteria. Hence it will not match with the Mycorrhiza.
