P cells are haploid
E are diploid
4

P cell wall
A
Peptigoglycan
5
Q
Virus
A
Replicate by budding off host
Various routes of infection eg faecal oral and vectors and air and water
Depend on host machinery eg just use reverse transcriptase to convert their virus RNA to DNA to proteins again
6

Divide by binary fission
Eg shigella spp. By faecal Oral transmission

Bud or divide
Hyphae filaments have cross walls
