Question

(i) Beyond what cell concentration , saturation density is achieved ? a) > 104 cells /ml
b) 104 to 105 cells /ml
c) > 105 cells /ml
d) > 106 cells /ml

Answer 1

Answer:

i think the correct answer is (c)

Answer 2

Answer:

Saturation density is achieved when More than 106 cells /ml

Option D

Explanation:

The cells in a culture medium follow an S shaped curve. The first phase in the growth is known as the "lag phase".There is no increase in "cell concentration" in the lag phase. This is because the cells need to get adjusted to the new surroundings.

This is followed by the log phase where there is exponential growth in population of the cell. Then the plateau phase is achieved. The phase in which there is saturation according to the graph is More than 106 cells /ml
