Aquatic plants often have thicker cuticles to reduce water loss and protect against excessive moisture exposure. While they are submerged in water, a thicker cuticle can help prevent the plant from becoming overly saturated and can also provide some protection from pathogens and herbivores. Additionally, a robust cuticle can aid in gas exchange by minimizing the entry of water while allowing for the exchange of gases necessary for photosynthesis.

Why is cuticle very thick in acquatic plants and desert plants?
The cuticle is very thick in aquatic plants and desert plants as a protective adaptation to their respective environments. In aquatic plants, a thicker cuticle helps prevent the loss of water due to evaporation, while also providing some protection from pathogens in the water. In desert plants, a thick cuticle serves to minimize water loss in an environment where moisture is scarce, helping them retain internal hydration. Both adaptations ensure that these plants can survive and thrive in their challenging habitats.
Why don't plants that live around water have a cuticle?
Plants that live around water, such as aquatic plants, do not need a thick cuticle because they do not face the same challenges of water loss as land plants. The aquatic environment provides constant access to water, so these plants have evolved to prioritize other adaptations, like increased surface area for gas exchange.
How does a cuticle in an aquatic plant differ from a desert plant?
In aquatic plants, the cuticle is often much thinner or even absent because they are submerged in water, allowing for easy gas exchange and nutrient absorption. In contrast, desert plants have a thick, waxy cuticle that helps minimize water loss and protect against harsh environmental conditions. This adaptation is crucial for survival in arid environments, where conserving moisture is essential for the plant's survival.
Do angiosperms often have a thick cuticle?
Yes, angiosperms (flowering plants) frequently have a thick cuticle on their leaves. The cuticle helps reduce water loss through evaporation and provides protection against environmental stresses like drought and pathogens.
What does the thick waxy cuticle do on the epidermis of plants?
The thick waxy cuticle on the epidermis of plants helps prevent water loss by creating a barrier that reduces transpiration. It also provides protection against harmful UV radiation, pathogens, and insects. Additionally, the cuticle can help reduce mechanical damage to the plant's surface.
Why is cuticle a useful adaptation in plants but not in algae?
The cuticle is a useful adaptation in plants but not in algae because: in order for plants to live on land, they need a cuticle to prevent water loss during dry climates. Algae live in the water, therefore they don't need a cuticle to survive. They use their adaptations to absorb the water and nutrients around their watery environments. Source: My straight "A" brain
Were would a plant with a thick cuticle come from?
The desert; a thick cuticle will prevent/reduce water loss
How is transpiration related to cuticle?
Thick cuticle limits transpiration.
Where do plants without a cuticle live?
Plants without a cuticle live underwater. The purpose of the cuticle is to prevent the leaves of a plant from losing moisture to the atmosphere. Pine needles have a thick waxy coating that prevents moisture loss during the winter, when the air is dry. Cacti have modified leaves that are mostly cuticle, because the use their stems for photosynthesis. Plants that spend one season underwater and on season out of water actually grow new leaves every time the seasons change- the land leaves have a waxy cuticle, while the under water leaves are thin and flimsy. The cuticle also gives hardness to leaves, which shapes lets them sty upright rather than drooping.
Why was desert plant have a thick waxy cuticle?
Let's think about this for a minute and you'll figure it out. Do they need to be protected from extreme temperature? Do they need something to keep water from evaporating too quickly and drying them out? Yes, so they'd need a thick protective cuticle.
Does the cuticle in plants contain chlorophyll?
No, cuticle does not contain chlorophyll.
Why do cacti have a thick cuticle?
For protection against fauna
