Leaf Anatomy

Leaf vascular tissue is located within the mesophyll layer. Sometimes leaves are divided into two or more sections called leaflets.

Leaf Anatomy

Leaf anatomy the leaf is the primary photosynthetic organ of the plant.

Leaf anatomy. Different plant cell types form three main tissues found in leaves. The blade has many layers that not only help the plant move but also help it store. Typically a leaf consists of a broad expanded blade the lamina attached to the plant stem by a stalklike petiole.

These tissues include a mesophyll tissue layer that is sandwiched between two layers of epidermis. The outer layers of the leaf are designed to protect it serving as a strong barrier. It consists of a flattened portion called the blade that is attached to the plant by a structure called the petiole.

The petiole mechanically links the leaf to the plant and provides the route for transfer of water and sugars to and from the leaf. Leaves have special structures and shapes according to the environment in which they grow. Parts of a leaf the main light collecting structure on a leaf is a large broad flat surface called the leaf blade.

The tremendous variety shown in leaf structure anatomy from species to species is presented in detail below under morphology. The internal anatomy of leaves is complex with many layers. Leaves are however quite diverse in size shape and various other characteristics including the nature of the blade margin and the type of venation arrangement of veins.

Underneath the barrier layers the leaf has special layers that enable it to process sunlight. Leaf tissues are composed of layers of plant cells.
