A,)
How much time will two E. Coli cells take to become 32 cells if the average duplication time of E. coil is 20 minutes?
1 hour - 20 minutes
These are the 4 subsequent cell divisions to produce 16 cells and each division takes =20 min
No. of cells formed after each division is 2 to form 32 cells, the E.coli cells need to undergo 5 division cycles, (25 ) = 32 cells
The duration for each cycle is 20 mins.
Therefore, the total time required for 5 cycles is 20 X 5 =100 min or 1 hr 40 mins

What is the role of centrioles apart
from spindle formation?
The two centrioles in the centrosome lie perpendicular to each other. Each has organisation like a cart wheel. These form the basal body of cilia and flagella of plant/animal cells besides forming spindle fibre in animal cell division. It also helps in the formation of microtubuless and sperm tail.
