What is the main function of a plant cover?

The main function is to protect the plant from environmental factors such as weather conditions and pests.

What are the two main types of plant coverings?

The two main types are epidermis and periderm.

What is the epidermis in plants?

The epidermis is a single layer of cells covering the leaves, flowers, roots, and stems of plants.

What is the role of the cuticle in plant coverings?

The cuticle helps reduce water loss from the plant surface.

How does the epidermis protect the plant?

It serves as a barrier against injury, infection, and water loss.

What is the periderm?

Periderm is the protective tissue in plants that replaces the epidermis during secondary growth.

In which types of plants is periderm commonly found?

Periderm is commonly found in woody plants, such as trees and shrubs.

What is cork, and where is it found in plants?

Cork is a tissue found in the periderm that provides protection and reduces water loss.

What is the importance of the stomata in the plant epidermis?

Stomata are pores that allow gas exchange and transpiration.

How do trichomes help in plant protection?

Trichomes can deter herbivores, reduce water loss, and provide protection from harmful sun rays.

What is lignin and what role does it play in plant coverings?

Lignin is a complex organic polymer that provides rigidity and does not rot easily, helping to protect plant tissues.

Why is the cuticle especially important for plants in dry environments?

It minimizes water loss, which is critical for survival in arid conditions.

How does the periderm help in plant growth?

Periderm replaces the epidermis during secondary growth, allowing the plant to grow thicker and protect underlying tissues.

What adaptations do desert plants have related to their coverings?

Desert plants often have thick cuticles, reduced leaves, and trichomes to minimize water loss.

How do plant coverings interact with fungi and bacteria?

Plant coverings act as a barrier to prevent the entry of pathogens like fungi and bacteria.
