Leaf Structure Cross Section

Leaves contain a number of different tissues and cell types arranged in a particular way.
Leaf structure cross section. The epidermis is covered by a cuticle and has stomata pores with guard cells that can open and close the pores. Leaf tissues are composed of layers of plant cells. The uppermost and lowermost layers are the epidermis.
A protective layer of cells that produces the cuticle. A cross section through a leaf features of leaves and their functions the role of stomata the stomata control gas exchange in the leaf. This is a description of a leaf cross section at the cellular level.
Different plant cell types form three main tissues found in leaves. A leaf is made of many layers that are sandwiched between two layers of tough skin cells called the epidermis. Leaf cross section showing tissues and cells.
Leaf vascular tissue is located within the mesophyll layer. The diagram above shows the blade lamina of a dorsiventral leaf in cross section with layered tissues. The epidermis also secretes a waxy substance called the cuticle.
The epidermis is is also transparent and very thin to allow maximum light penetration. A waxy layer that prevent water loss by evaporation. These layers protect the leaf from insects bacteria and other pests.
The cuticle is transparent and very thin to allow maximum light penetration.
