Hypothesis:Photosynthesis is a process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose....
During the process of photosynthesis, carbon dioxide plus water in the presence of sunlight, enzymes and chlorophyll produce glucose and oxygen as waste product.
Background information: Photosynthesis Photosynthesis is the process of autotrophs turning carbon dioxide and water into carbohydrates and oxygen, using light energy from sunlight.
These cells contain most of the leaf's chlorophyll, converting sunlight into usable chemical energy for the plant.
- the margins between the irregular teeth go more than halfway to the midrib.
- a leaf stalk; it attaches the leaf to the plant.
- the process in which convert sunlight, water, and into food energy (sugars and starches), oxygen and water.
These cells convert sunlight into usable chemical energy for the plant.
- the central rib of a leaf - it is usually continuous with the petiole.
- a layer of elongated cells located under the upper epidermis.
Generally, many more stomata are on the bottom of a leaf than on the top.
- Veins provide support for the leaf and transport both water and minerals (via xylem) and food energy (via phloem) through the leaf and on to the rest of the plant.
The spongy mesophyll cells communicate with the guard cells (stomata), causing them to open or close, depending on the concentration of gases.
- (also called the axis) the main support of the plant.
- the small, paired appendages (sometimes leaf-life) that are found at the base of the petiole of leaves of many flowering plants.
- (plural stomata) a pore (or opening) in a leaves where water vapor and other gases leave and enter the plant.
There is often a single terminal leaflet at the end of the midrib.
- having small, pointy teeth that point toward the tip of the leaf.
- the layer below the palisade mesophyll; it has irregularly-shaped cells with many air spaces between the cells.

or closely-related pigments (substances that color the plant) are essential to the photosynthetic process.
- a compound leaf that is made up of many small arranged in pairs on either side of a long central (the ).

Guard cells change shape (as light and humidity change), causing the stoma to open and close.
- the blade of a leaf.
- the outer end of a leaf; the end that is opposite the petiole.
- divided into rounded or pointed sections and the incisions (cuts) go less than halfway to the midrib.
- the chlorophyll-containing leaf tissue located between the upper and lower epidermis.
The rate of photosynthesis actually seemed to be picking up around the 9th and 10th leaf, this could mean another experiment with more than 10 leaves should follow to see how much higher the rate will increase and when it will finally start declining.
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).
