• D. Opening of flowers

Answer 1

The correct option is A Exchange of gases

• During the process of diffusion CO2 diffuse into leaves to the cells,however oxygen and water vapour creatd by photosynthesis is release out of the cells hence exchange of gases carry out the process of diffusion .
  
• Transpiration is a procees in which plant absorbs the water through roots and then give offs water vapour to leaves .
  
• Absorption of water by roots is a simple process of absorption of water from soil through hair like extension of roots by process called osmosis.
  
• Flower opening ir closing are the traits of reproductive syndrom, as it allows pollen removal and polination.
  
• hence the correct answer is "exchange of gases".
