Statement II - Polysaccharides are too big to escape from the cell.
In the light of above statements, select the correct option given below:
Given below are two statements.
Statement I - All monosaccharides are reducing sugars.
Statement II - Polysaccharides are too big to escape from the cell.
In the light of above statements, select the correct option given below:
Show Hint
Check each statement separately: free aldehyde or ketone groups and molecular size.
Updated On: Nov 13, 2026
Both statement I and statement II are correct.
Both statement I and statement II are incorrect.
Statement I is correct but statement II is incorrect.
Statement I is incorrect but statement II is correct.
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept
Monosaccharides have a free aldehyde or ketone group (ketoses isomerise to aldoses in alkaline medium), so all of them reduce Benedict's or Fehling's reagent.
Statement I is correct.
Step 2: Key Point
Polysaccharides such as starch, cellulose and glycogen are very large polymers.
Their large size keeps them from leaving the cell, so they act as storage or structural molecules.
Statement II is correct.
Step 3: Compare the options
Both statements are correct.
Final Answer:
Both statements are correct. \[ \boxed{\text{(A) }\text{Both statement I and statement II are correct.}} \]
