|
Metabolism |
All chemical processes that synthesize or break down materials within an organism. |
|
|
Chlorophyll |
A light absorbing pigment molecule found in the thylakoid membranes of the chloroplast |
|
|
Photosynthesis |
Process by which light energy is converted to chemical energy; produces sugar and oxygen from carbon dioxide and water |
|
|
Stoma |
Pore in the cuticle of a plant through which gas exchange occurs (carbon dioxide in and oxygen out) |
|
|
Mesophyll cells |
Photosynthetic tissue of a leaf, located between the upper and lower epidermis. |
|
|
Light Dependent Reaction |
Part of photosynthesis that absorbs energy from sunlight, splits water molecules, and transfers energy to the light-independent reaction giving off oxygen as waste. |
|
|
Light Independent Reaction |
Process of photosynthesis that uses energy from the light dependent reaction to synthesize glucose from carbon dioxide in the stroma of a chloroplast |
|
|
Energy Cycle |
A cycling of energy where the products of one reaction become the reactants of another and energy is recycled in the process |
|
|
Glucose |
A high energy six carbon sugar molecule made by plants during photosynthesis, it is a monomer of carbohydrates. |
|
|
NADP+/NADPH |
A high energy molecule that contains, within its bonds, energy that cells can use |
|
|
Vascular Tissue |
A system of tubes that transports water and food to all parts of the plant |
|
|
Xylem |
The vascular tissue that carries water and dissolved minerals up from the roots to the rest of the plant. |
|
|
Phloem |
The vascular tissue that carries the products of photosynthesis (food-glucose) to the rest of the plant. |
|
|
Cuticle |
A waxy coating on the top and bottom of the leaf for protection and water-proofing |
|
|
Chloroplast |
Membrane bound organelle found in mesophyll cells that is the site of photosynthesis |
|
|
Thylakoid |
Membrane-bound structure within chloroplasts that contains chlorophyll used in the light dependent reaction of photosynthesis. |
|
|
Granum |
Stacks of coin-shaped, membrane enclosed compartments called thylakoids |
|
|
Stroma |
Fluid filling the space within the chloroplasts, outside of the thylakoids |
