  3. on what basis did he divide the kingdoms into 3 domains of life
  4. what was the common ancestor called
A
  1. archaebacteria, eubacteria, protista, fungi, plantae, animalia

38
what are cyanelles
when cyanobacteria live endozoically in protozoans
39
what are cyanobacteria characterised by
-absence of flagella throughout life cycle -4 layered cell wall -central colourless centroplasm, peripheral protoplasm is -pigmented due to thylakoids called chromoplasm -lamellosome connects membrane to nucleoid -sap vacuoles are replaced by gas vacuoles
40
what are the pigments in cyanobacteria
phycocyanin (blue) phycoerythrin (red) allophycocyanin (light blue) chlorophyll a
41
describe photosytems in heterocysts
it lacks ps-ii and co2 is only done in vegetative cells it has ps-i tho which generates ATP required to fix N2

45
what are the various names of PPLO and who named them
borrel named it asterococcus mycoides and nowak named it mycoplasma
46
describe the reproduction of mycoplasma and also their dna
they reproduce by formation of elementary bodies they have liner double stranded dna extending throughout the cell
47
