Stomata of CAM plants
1 Open during the night and close during the day
2 Never open
3 Are always open
4 Open during the day and close at night
Explanation:
A CAM plants open their stomata at night decreasing water loss \& increasing water use efficiency as well as drought tolerance.

A decrease in photosynthetic rate with increased availability of oxygen is called:
1 Warburg effect-
2 Richmond Lang effect
3 Blackmans law of limiting factors
4 Emerson enhancement effect
Explanation:
A An increase in $\mathrm{O}_{2}$ concentration result in decrease in photosynthetic rate is effect is called Warburg effect.

If oxygen content is reduced to $1 \%$ the rate to respiration becomes
1 optimum
2 minimum
3 maximum
4 None of these
Explanation:
B If the rate of respiration is higher or directly depends on the concentration of available oxygen. Increase in $\mathrm{O}_{2}$ concentration increases the rate of respiration.
