Hydrophytes do not have a cuticle on their stems or leaves because they live in an aquatic environment where water is abundant. The absence of a cuticle allows for direct absorption of water and nutrients from the surrounding water. The lack of a cuticle also prevents water loss through transpiration, which is not a concern for hydrophytes.

Why hydrophytes do not have cuticle on srem or leaves?
Hydrophytes do not have a thick cuticle on their stems or leaves because they do not need to conserve water in the same way as plants in drier environments. A reduced cuticle allows for increased gas and nutrient exchange with the surrounding water. This adaptation helps hydrophytes thrive in their aquatic habitat.
Why the root epidermis is not coated with a waxy cuticle?
The root epidermis is not coated with a waxy cuticle to allow for the absorption of water and minerals from the soil. A waxy cuticle would act as a barrier preventing water uptake through the roots. Therefore, the lack of a cuticle on the root epidermis is essential for the plant's ability to absorb nutrients from the environment.
What are the external parts of stem?
The external parts of a stem include the epidermis (outermost layer), the cortex (region beneath the epidermis), vascular bundles (tissue that transports water and nutrients), and the cuticle (waxy layer that helps prevent water loss).
What are hydrophytes give ten examples?
Hydrophytes are plants that grow in water or in very wet soil. Ten examples of hydrophytes include water lilies, water hyacinth, cattails, duckweed, lotus, water lettuce, water milfoil, bulrushes, reeds, and watercress.
What is waxy waterproof coating on plants is called?
The waxy waterproof coating on plants is called cuticle. It helps reduce water loss and protects the plant from environmental stresses.
Why hydrophytes do not have cuticle on srem or leaves?
Hydrophytes do not have a thick cuticle on their stems or leaves because they do not need to conserve water in the same way as plants in drier environments. A reduced cuticle allows for increased gas and nutrient exchange with the surrounding water. This adaptation helps hydrophytes thrive in their aquatic habitat.
How would you describe the adaptive features of hydrophytes?
Hydrophytes have adaptive features such as presence of air spaces in tissues for buoyancy, reduced cuticle to facilitate gas exchange, and specialized root systems for anchorage and nutrient uptake in waterlogged conditions. Additionally, hydrophytes may have flexible stems and leaves to reduce water resistance and adaptations for efficient water and nutrient uptake.
What is the role play of a cuticle on the stem?
The cuticle on the stem acts as a protective barrier, helping to prevent water loss and reduce the risk of pathogen entry. It also provides some degree of protection against herbivores and helps to regulate gas exchange through stomata. Additionally, the cuticle can affect the stem's appearance by giving it a glossy or matte finish.
Where can a cuticle be found on a plant?
On the epidermis of leaf, stem and fruit wall etc.
How does air enter and leave the leaf?
Stomata.
What are some differences between xerophyte and phreatophyte?
Xerophytes are known for having stomata that are fewer in number, sunken, waxy and\or open only at night. Hydrophytes often lack cuticle, because there is no need to prevent water loss. stomata are larger in quantity and typically open.
Is broccoli leave or stem vegetable?
.Broccoli is a stem veg.
The cuticle in plants?
The cuticle is the waxy waterproof layer on the leaves (it is thicker on the top, but there is also a thin layer underneath the leave), which prevents excessive water loss.
