- Why is a block of agar inoculated rather than streaking the fungal culture on a plate?Tell me 3 things about each one? are they selective , differential , positive , negative results etc. gram stain isolation streak ftm tubesWhy is it important to limit the quantity of cells used to prepare a smear? Mark all that apply: 1. So that cells are not clumped and don't entrap stain creating erroneous results 2. So that the cells are spread out enough that cell morphology can be discerned 3. So that there are small groups of cells clumped together to make them visible 4. So that no contaminants are introduced onto the slide by being entrapped in clumps 5. So that the cells are spread out enough that the arrangement can be observed
