Anatomy Of Leaf

The thick cuticle formed of cutin protects the laminathe veins help in conduction of water and translocation of food in the leaf tissues. Chloroplasts contain chlorophyll a green plant pigment that captures the energy in light and begins the transformation of that energy into sugars.

Anatomy of dicotyledonous and monocotyledonous plants. A leaf is made of many layers that are sandwiched between two layers of tough skin cells called the epidermis. Leaf anatomy the leaf is the primary photosynthetic organ of the plant.

Most leaves are broad flat and typically green in color. The leaf like organs of bryophytes eg mosses and liverworts known as phyllids differ morphologically from the leaves of vascular plants in that they lack vascular tissue are usually only a single cell thick and have no cuticle stomata or internal system of intercellular spaces. The top most layer of a leaf is called the upper epidermis.

The venation forms the framework or the basic skeleton of the leaf blade. It is also called the lamina. Learn vocabulary terms and more with flashcards games and other study tools.

It consists of a flattened portion called the blade that is attached to the plant by a structure called the petiole. Chloroplasts sub cellular photosynthetic structures in leaves and other green tissues.
