aids in photosynthesis and has column-shaped, tightly-packed cells.

On each side of the stoma there is a guard cell with chloroplasts." title="Internal structure of a leaf" height="380" width="546" style="margin-bottom: 0px;">The internal structure of the leaf is also adapted to promote efficient photosynthesis:
Photosynthesis is extremely important in the plant’s nutrition
To a plant, leaves are food producing organs. Leaves "absorb" some of the energy in the sunlight that strikes their surfaces and also take in carbon dioxide from the surrounding air in order to run the metabolic process of photosynthesis. The green color of leaves, in fact, is caused by an abundance of the pigment "chlorophyl" which is the specific chemical agent that acts to capture the sunlight energy needed for photosynthesis. The products of photosynthesis are sugars and polysaccharides. An important "waste product" of photosynthesis is oxygen. To an animal, a leaf may be a food source or a place to live on or under (i.e. a "habitat").

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).
The WAXY CUTICLE helps reduce water loss
Heterotrophic organisms such as fungi and bacteria obtain the energy they need for growth, reproduction, and movement by decomposing other organisms or molecules. Members of the Kingdom Plantae, together with some members of the Kingdom Protista and all of the cyanobacteria (Domain Bacteria), are photosynthetic organisms; as such, they are autotrophs: they synthesize their own food by using simple raw materials plus the energy of sunlight. They are responsible for renewing the energy supplies available on the Earth. Coal, gasoline, and heating oil fuel our society. These sources of energy are largely derived from the metabolic activity of plants that lived millions of years ago. Members of the Kingdom Animalia, heterotrophic organisms including ourselves, obtain energy from the food they eat. In addition, the process of photosynthesis is the source of oxygen required for the respiration of both plants and animals.
