The ${\mathrm{C}}_4$ plants are photosynthetically more efficient than ${\mathrm{C}}_3$ plants because

Process of photosynthesis that occur in the stroma lamellae membranes, lack:

Regarding photosynthesis, Jan Ingenhousz established the essentiality of sunlight and green colour respectively by using :-

Dark reactions of photosynthesis:

There is a linear relationship between light and ${\mathrm{CO}}_2$ fixation rates at $\dots \dots \dots \dots ..$ intensities. At $\dots \dots \dots \dots .$ intensities the rate does not show further increase as other factors become limiting.
Choose the correct terms for blanks respectively-

In photorespiration-

In the biosynthetic phase of photosynthesis the first ${\mathrm{CO}}_2$ fixation product is a 3 -carbon organic acid. This fact was discovered by Melvin Calvin :-
