36
ENDOSPORE FORMATION IS MOSTLY SEEN IN
BACILLUS BACTERIA DURING UNFAVOURABLE CONDITIONS
37
Endospore has maximum resistance due to ............. in their wall
Ca- dipicolenate
38
Name the product of reproduction that is highly resistant to unfavourable conditions
endospore

BInary fission
40
Type of reproduction in which genetic material is transferred via bacteriophage
Transduction
41

42
name the pigments present in blue-green algae along with their colours
Chlorophyll a-green Carotenoids- yellow C-phycocyanine- blue C-phycoerythrin- red
43
What is the organism that is responsible for red tide
Trichodesmium erythrum (cyanobacteria)
44
Name some uses of SCP
used in dietary supplements, fodder for cattle, be grown in tanks
45
Name some colonial cyanobacteria
Anabaena and microcysts- they form shiny colonies and are covered with slimy mucilagenous sheath
46

The membrane of mycoplasma is made of
lipoprotein
64
Why is mycoplasma resistant to penicillin
Since it lacks a cell wall
65
Mycoplasma are susceptible to tetracycline, chloramphenicol since
