Answer 2

The outer thick waxy covering prevents water from escaping the cactus plant.

Why does the cactus have cuticles?

• Cactus are desert plants and fall under the category of succulents because they have a waxy outer layer called cuticles on their stems and leaves.
• In order to survive in the harsh heat of the desert, cactus plants have a layer of cuticle. This layer prevents the loss of water that occurs through transpiration in plants.
• The stomata on the stem of cacti are also fewer compared to other plants to save and store water in situations of scarcity.
• The cactus has also evolved to develop a mechanism to protect itself from being eaten by grazing animals.
• They have pointy spines instead of leaves which keep the grazers away.
