✓
Answer
The significances of $C _4$ cycle:
1. Plants having $C _4$ cycle are mainly of tropical and sub - tropical regions and are able to survive in environment with low $CO _2$ concentration.
2. $C _4$ plants are partially adapted to drought conditions.
3. Oxygen has no inhibitory effect on $C _4$ cycle since PEP carboxylase is insensitive to $O _2$.
4. Due to absence of photorespiration, $CO _2$ Compensation Point for $C _4$ is lower than that of $C _3$ plants.
