Photosynthesis
Term | Definition |
---|---|
Photosynthesis | The process where green plants absorb energy from the sun and combine it with water and carbon dioxide to create glucose and oxygen. |
Sun | A form of kinetic energy that travels through space by wave particles, makes life on Earth possible, and can be absorbed, transmitted, or reflected. |
Reactants | Input; the items that go into a chemical reaction. |
Products | Output; the items that come out of a chemical reaction. |
Chlorophyll | A green pigment that is contained in chloroplasts that absorbs most of the visible light spectrum except for green, which is reflected. |
Chloroplasts | A structure inside plant cells that absorbs visible light that makes photosynthesis possible. |
CarbonDioxide | A gas that enters the plant and is needed for photosynthesis. |
Water | A liquid that enters the plant and is needed for photosynthesis. |
Oxygen | A gas that is release from the plant as a product of photosynthesis. |
Glucose | A Simple Sugar; that is a product of photosynthesis and food the producer makes. |
Green Plants | Plants that contain chloroplasts. |
Visible Light | Energy that is vital for plants to make their own food. |
Plant Cell | Eukaryotic cell that has chloroplasts and a cell wall. |
Stomata | A structure of a plant that is a pore on the under side of the leave that allows the exchange of gases. |
Xylem | Plant structure in vascular plants that transports water and nutrients from the roots to the leaves of a plant. |
Phloem | Plant structure in vascular plants that transports food from the leaves to the rest of the plant. |
Guard Cells | A structure of a plant that closes off the stomata when it is not needed. |
Respiration | The chemical process to unlock the energy in the glucose produced by photosynthesis. |
