alleryStomata on leaves help in:
APhotosynthesis only
BTransport of water uphill
CStorage of starch only
DGas exchange and transpiration
Answer & Solution
Correct answer: D. Gas exchange and transpiration
1. Stomata are tiny pores on leaf surface flanked by guard cells.
2. Allow gas EXCHANGE (CO₂ in for photosynthesis; O₂ out + O₂/CO₂ in/out for respiration).
3. Also water-vapour LOSS (transpiration), which creates the pull that draws water from roots up the xylem.
