Acell with normal tonicity is placed in a 200 mm nacl solution. this solution is and the cell will

The concentration of a cell is generally 0.15 M  (0.9 % NaCl)

As given the solution has concentration = 200mm = 0.02 M

This concentration of solution is less than the concentration of cell

Hence solution is hypotonic (less concentration) and cell will be hypertonic

the answer would be a

answer: they produce more slow than unicellular organisms.
