Photosynthesis in Higher Plants
| 209
TËMPËRÅTÜRË
Dark reactions, being enzymatic, are temperature controlled.
Influence of temperature on Light reactions is very less.
The C4 plants respond to higher temperatures and show higher
rate of photosynthesis.
C3 plants have a much lower temperature optimum.
The temperature optimum of plants also depends on their
habitat. Tropical plants have a higher temperature optimum
than the plants adapted to temperate climates.

Water
stress
closes
the
stomata hence reduce the
CO2 availability.
Water stress also wilts leaves,
thus
reduce
the
surface
area of the leaves and their
metabolic activity.
