Answer:
The given statement is true.
Different plants have evolved different types of carbon fixation methods as an adaptation towards varying conditions.
Majorly, these adaptive methods are named as C₃, C₄, and CAM.
C₃ plants: It is a normal method of carbon fixation in which enzyme RuBisCO fix carbon into sugars. It is named as C₃ as the first stable compound is a three-carbon compound that is, 3-Phosphoglyceric acid (3-PGA).
C₄: It is mainly found in plants which are present in hot regions such as vascular plants (like sugarcane, corn, crabgrass). The light and dark reactions are physically separated. The dark reaction takes place in bundle-sheath cells. The first stable compound is four carbon compound that is, oxaloacetate.
CAM: Plants like cacti, pineapples et cetera which inhabits dry environment practice this method. These plants separate the light and dark reactions into time instead of space.
