plant cuticle

It is found in plant cuticle waxes and in beeswax.

Plant cuticle is more prone to preservation if it contains cutan, rather than cutin.

It occurs naturally in the epicuticular wax and plant cuticle of many plant species.

Cutinite is a liptinite maceral formed from terrestrial plant cuticles, and often found in coal deposits.

A waxy Plant cuticle on the leaf surface also prevents evaporation from the leaf surface.

Entry can occur through direct penetration of the plant cuticle/epidermis or by means of natural openings in the plant.

The main structural components of plant cuticles are the unique polymers cutin and/or cutan, impregnated with wax.

The Plant cuticle is a protective film covering the epidermis of leaves, young shoots and other aerial plant organs without periderm.

It is interrupted by the Casparian strip in roots, by air spaces between plant cells and by the plant cuticle.

In plants, the solid long-chain alkanes are found in the plant cuticle and epicuticular wax of many species, but are only rarely major constituents.

Cutin is one of two waxy polymers that are the main components of the plant cuticle, which covers all aerial surfaces of plants.

Although initially covered by the plant cuticle, the fungus is later exposed when the cuticle peels off to reveal an ostiolate, leathery ascomata.

In botany, plant cuticles are protective, hydrophobic, waxy coverings produced by the epidermal cells of leaves, young shoots and all other aerial plant organs.

Hard pellets are made up of hay-like fragments of plant cuticle and stalk, being the final waste product after redigestion of soft pellets.

Turgor pressure increases inside the appressorium and a penetration hyphae emerges at the pore, which is driven through the plant cuticle into the underlying epidermal cells.

Polyesters include naturally occurring chemicals, such as in the cutin of plant cuticles, as well as synthetics through step-growth polymerization such as polycarbonate and polybutyrate.

The outer part of the primary cell wall of the plant epidermis is usually impregnated with cutin and wax, forming a permeability barrier known as the plant cuticle.

While polyunsaturated fatty acids are unusual in plant cuticles, a diunsaturated dicarboxylic acid has been reported as a component of the surface waxes or polyesters of some plant species.

Epicuticular wax can now also be isolated by mechanical methods that distinguish the epicuticular wax outside the plant cuticle from the cuticular wax embedded in the cuticle polymer.

The Transfersome vesicles usage in drug delivery consequently relies on the carrier's ability to widen and overcome the hydrophilic pores in the skin or some other (e.g. plant cuticle) barrier.

For example, the components of the plant cuticle and epicuticular waxes are synthesized in the epidermal cells from palmitic acid synthesized in the chloroplasts of mesophyll cells.

In botany, the plant cuticle is covered by epicuticular wax or bloom consisting mainly of straight-chain aliphatic hydrocarbons with a variety of substituted groups, serving to decrease surface wetting and moisture loss.

The holes in the cuticle which allow for this digestive mechanism also pose a challenge for the plant, since they serve as breaks in the Plant cuticle (waxy layer) that protects the plant from desiccation.

The organic components of oil shale derive from a variety of organisms, such as the remains of algae, spores, pollen, plant cuticles and corky fragments of herbaceous and woody plants, and cellular debris from other aquatic and land plants.
