All insect plagues the leaf has your company grown.
An example of a leaf is the part of the tree that is green in the summer and may change colors and fall off of the tree before the start of winter.
The leaves will give off oxygen through the stomata and out into the environment, where it is used by other living organisms. To produce a single molecule of glucose to feed the tree, a leaf must take in six molecules of carbon dioxide. In return, the leaf then releases six molecules of oxygen back into the environment. One average tree will produce about 260 pounds of oxygen in a year.

The surface of many leaves is coated with a waxy cuticle which is secreted by the epidermis.
- one of a pair of sausage-shaped cells that surround a stoma (a pore in a leaf).
The cuticle is generally thicker on plants that live in dry environments.
- having a smooth edge with neither teeth nor lobes.
- the protective, outler layer of cells on the surface of a leaf.

These gaps are filled with gas that the plant uses (carbon dioxide - CO ) and gases that the plant is expelling (oxygen - O, and water vapor).
- the angle between the upper side of the stem and a leaf or petiole.
- a molecule in leaves that can use light energy from sunlight to turn water and carbon dioxide gas into sugar and oxygen (this process is called photosynthesis).
Plants absorb water through their roots, and carbon dioxide through their leaves. Some glucose is used for respiration, while some is converted into insoluble for storage. The stored starch can later be turned back into glucose and used in respiration. Oxygen is released as a by-product of photosynthesis.

Photosynthesis 3-D Leaf Model (Color and B&W) by …
They are trying to get around one the conundrums of photorespiration, the process by which as CO2 is taken from the air and fixed into carbon for the plant to use to grow. This natural process creates a toxic compound called phosphoglycolate that the plant needs to get rid of. Natural selection’s response has been to recycle it back into the chemical machinery of the photosynthetic machine. But this releases CO2, exactly what the plant needs to grow, and uses cellular resources that could otherwise be devoted to growth and, from a human perspective, making plant parts that we could eat.

One ambitious team is led by Dr Arren Bar-Even of the Max Planck Institute of Plant Physiology in Potsdam, Germany, who leads the FutureAgriculture project. “Most projects to improve photosynthesis are trying to take the low hanging fruit. We are trying to engineer pathways that could have a much higher effect on productivity — a more high-risk, high-gain kind of approach.”

Photosynthesis is the process by which leaves make food for a plant. Carbon dioxide and water enter the stomata through the underside of the leaves. As sunlight shines on the tops of the leaves, the chloroplasts begin the process of converting the sunlight to energy to nourish the plant. Chloroplasts have a pigment called chlorophyll, which is the vital ingredient needed for photosynthesis. Chlorophyll molecules absorb light energy to enable photosynthesis. The two byproducts of photosynthesis are carbohydrates and oxygen. The plant will use the carbohydrates as food to sustain it.
PHOTOSYNTHESIS - Estrella Mountain Community College
The epidermis of the leaf has tiny pores called stomata. These pores are openings that take in and release gases. Many leaves close off the stomata during the nighttime hours to keep the leaves from losing too much moisture. As leaves release water molecules through the stomata, they help cool the air. Releasing moisture is called transpiration, and it is one reason why trees are beneficial for the environment.

The internal anatomy of leaves is complex with many layers. The outer layers of the leaf are designed to protect it, serving as a strong barrier. Underneath the barrier layers, the leaf has special layers that enable it to process sunlight. Leaves have special structures and shapes according to the environment in which they grow.
