Chloroplasts contain chlorophyll a green plant pigment that captures the energy in light and begins the transformation of that energy into sugars. Basic leaf features in angiosperms flowering plants include the leaf blade petiole and stipules.

The leaf blade and the stalk or the petiole.

Anatomy of leaf. Vascular bundle xylem and phloem tissues commonly known as leaf veins. Leaf in botany any usually flattened green outgrowth from the stem of a vascular plant. Anatomy of dicotyledonous and monocotyledonous plants.

Its generally broad and flat. Most leaves are broad flat and typically green in color. It is in this layer that photosynthesis occurs.

It is also called the lamina. Leaf anatomy the leaf is the primary photosynthetic organ of the plant. As the primary sites of photosynthesis leaves manufacture food for plants which in turn ultimately nourish and sustain all land animals.

Leaf shape is adapted to best suit the plants habitat and maximize photosynthesis. Start studying leaf anatomy. Chloroplasts sub cellular photosynthetic structures in leaves and other green tissues.

The thick cuticle formed of cutin protects the laminathe veins help in conduction of water and translocation of food in the leaf tissues. It consists of a flattened portion called the blade that is attached to the plant by a structure called the petiole. Some plants such as conifers have leaves that are shaped like needles or scales.

The next layer is the palisade mesophyll which is a layer of closely packed cells that perform photosynthesis. The epidermis also secretes a waxy substance called the cuticle. This protects the leaf and may be covered by a waxy cuticle.

These layers protect the leaf from insects bacteria and other pests. Parts of a leaf. 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 venation forms the framework or the basic skeleton of the leaf blade. As per anatomy of leaf the lamina is the principal site for photosynthesis. A leaf is made of many layers that are sandwiched between two layers of tough skin cells called the epidermis.

Learn vocabulary terms and more with flashcards games and other study tools. The third layer is the spongy mesophyll a layer of loosely packed photosynthetic cells. Among the epidermal cells are pairs of sausage shaped guard cells.

Leaves have two main parts. The top most layer of a leaf is called the upper epidermis.
