Q. Choose the correct statements I. Passive cells are larger in size II. Larger cells have lower surface volume ratio III. To remain active, larger cells are either cylindrical in shape or possess several extensions of the cell membrane, like microvilli IV. Microvilli are found in all those cells, which are active in absorption V. Microvilli (membrane infoldings) occurs in transfer cells found in plants in the region of absorption or secretion of nutrients Option containing all correct statements is
A) I and IV
B) I, II, III and IV
C) I, III and II
D) I, II, III, IV and V
Explanation
All passive cells like eggs are larger in size. Larger cells have lower surface volume ratio. All active cells are smaller. If larger cells has to remain active, they are either cylindrical in shape or possess several extensions of the cell membrane. Microvilli are one of such developments. They are found in all those cells, which are active in absorption. These also occur in transfer cells found in plants
