1. NEET 2026EasyMechanisms of Water Movement
   Q1

   The main function of bulliform cells in grasses is:

   • Ato make the leaf impermeable to fungal spores.
   • Bto transport water.
   • Cto perform photosynthesis.
   • Dto minimize water loss during water stress.

   Show answer & solution

   Correct answer: (D)

   Bulliform cells lose water and become flaccid, causing leaf curling to reduce water loss.
2. NEET 2023EasyMeans of Transport
   Q2

   Movement and accumulation of ions across a membrane against their concentration gradient can be explained by
   
   [NEET 2023]

   • AFacilitated Diffusion
   • BPassive Transport
   • CActive Transport
   • DOsmosis

   Show answer & solution

   Correct answer: (C)

   Movement and accumulation of ions across a membrane against their concentration gradient can be explained by active transport. It uses energy to transport molecules from lower concentration to a higher concentration.
3. NEET 2023HardTranspiration
   Q3

   Given below are two statements :
   
   Statement I: The forces generated transpiration can lift a xylem-sized column of water over 130 meters height.
   
   Statement II : Transpiration cools leaf surfaces sometimes 10 to 15 degrees evaporative cooling.
   
   In the light of the above statements, choose the most appropriate answer from the options given below :
   
   [NEET 2023]

   • ABoth Statement I and Statement II are incorrect
   • BStatement I is correct but Statement II is incorrect
   • CStatement I is incorrect but Statement II is correct
   • DBoth Statement I and Statement II are correct

   Show answer & solution

   Correct answer: (D)

   Statement I is correct as measurements reveal that the forces generated by transpiration can create pressures sufficient to lift a xylem sized column of water up to 130 meters high.
   
   Statement II is also correct as transpiration cools leaf surfaces, sometimes 10 to 15 degrees, by evaporative cooling.
