Final answer:
Succulent stems of aloe vera plants are beneficial because they help with water storage and provide support to the plant. They have adaptations that reduce water loss and allow the plant to survive in arid environments.
Step-by-step explanation:
Succulent stems are beneficial to aloe vera plants because they help with water storage. The enlarged fleshy stems of succulent plants like aloe vera are able to store water, allowing the plant to survive in arid environments. This is because succulent stems have adaptations such as waxy cuticles and sunken stomata, which reduce water loss.
In addition to water storage, the stems of plants also provide support to the plant, holding leaves, flowers, and buds. Stems also transport water and minerals absorbed by the roots to different parts of the plant, as well as transport sugars produced in the leaves through the process of photosynthesis to the rest of the plant.
