Q. Fill in the blanks:
1. Light saturation occurs at (a)_______ percent of full sunlight.
2. There is a (b)________ relationship between incident light and $CO_2$ fixation rates at low light intensities.
3. $C_3$ plants show saturation at about (c)____ $\mu lL^{— 1}$ while $C_4$ corresponds to saturation at about (d)_________$\mu l L^{-1}$.

Photosynthesis in Higher Plants

Solution:

1. Light saturation occurs at $10\%$ per cent of full sun light.
2. There is a linear relationship between incident light and $CO_2$ fixation rates at low light intensities.
3. $C_3$ plants show saturation at about $450 \,\mu l L^{-1}$ while $C_4$ corresponds to saturation at about $360 \,\mu l L^{-1}$
