The cuticle
It reduces the loss of water
Rolling up its leaves reduces the surface area exposed to the sun and wind, helping to minimize water loss through transpiration. This adaptation reduces the plant's water consumption and helps it survive in arid environments.
A waxy layer called the cuticle prevents water loss in leaves.
Stomata are typically located on the underside of leaves. This positioning helps to reduce water loss by minimizing exposure to direct sunlight and reducing the chances of evaporation. The presence of stomata on the underside of leaves also reduces the risks of damage from external factors such as wind and heat.
When a plant is placed in a plastic bag, the enclosed environment creates a high humidity level within the bag. This high humidity reduces the rate of transpiration, which is the process of water loss from the plant through its leaves. As a result, the plant conserves water and slows down the overall rate of water loss.

Extended drought causes a succulent's leaves to shrivel.Specifically, a succulent plant wants to expose the least amount of surface area to evaporation. Decreased surface area reduces the amount of water loss. Shriveling up therefore is a way to have a lesser amount of leaf surface available for water loss to take place.
Small leaves minimize water loss.
Transpiration
The loss of water from the leaves of plants is known as transpiration. It is a crucial process in which water is taken up by roots and released through leaf stomata as vapor. This helps in maintaining the plant's internal water balance.
They have shallow roots at the bottom of the plant which helps them not to fall down in strong winds.
