Which among the following adaptations help a cactus plant to minimise water loss?

The correct option is A Spine-like leaves

• The leaves of desert plants like cactus are modified to spines.
• This reduces the surface area and in turn, reduces the loss of water by transpiration.
• Spines also protect the desert plants from being eaten by animals.
• Their stem is usually green and fleshy. It performs photosynthesis and also stores water.
