Question

cactus: leaves reduced into spines
Fir:?​

Answer 1

Answer:

The leaves of a cactus have become spines to limit the loss of water through transpiration. The plant has to prevent water loss as there is very little rainfall in the areas of the cactus.

Explanation:

Spines are for protection. They keep away large predators, and the smaller hairs on these spines deter smaller ones. They keep air still near the body of the cactus to reduce transpiration ( the body or stem is what is photosynthetic on s cactus).
