Factors Affecting Photosynthesis

When two plants $\mathrm{L}$ and $\mathrm{M}$ were exposed to different light intensities and temperatures, they showed changes in their rates of photosynthesis, which have been represented in the following graph. 

The graph indicates that

Which of the following factor affects indirectly to the process of photosynthesis?

Water stress leads to

Light may be a limiting factor for

Which of the following is the limiting factor?

Internal factor of plant depends on

The external factors affecting photosynthesis are

Which of the following is not an internal factor that has role in photosynthesis?

Deactivation of enzymes above $40°\mathrm{C}$ affects the _________ of photosynthesis and decreases the rate of photosynthesis.
 

Assertion : Plants utilize $5-10\%$ of the absorbed water in photosynthesis.

Reason : Reduced leaf hydration decrease the photosynthesis.

Assertion : Sciophytes require higher light intensity than heliophytes.

Reason : Sciophytes grow below the canopy of trees.

Assertion :  The concentration of ${\mathrm{O}}_2$ in the atmosphere is inhibitory to photosynthesis.

Reason : Oxygen inhibitory effect is due to Warburg effect.
