Plant Processes
SOL7.5
Term | Definition |
---|---|
Photosynthesis | The synthesis of complex organic material using carbon dioxide, water, inorganic salts, and light energy (from sunlight) captured by light-absorbing pigments, such as chlorophyll and other accessory pigments. |
Respiration | Any of the various analogous processes by which there is an exchange of gases. |
Stomata | |
Guard Cells | plant cells occurring in pairs in the epidermis, flanking each stoma |
Chlorophyll | The green pigment found in the chloroplasts of higher plants and in cells of photosynthetic microorganisms (e.g. photosynthetic bacteria), which is primarily involved in absorbing light energy for photosynthesis. |
Chloroplast | Chlorophyll-containing plastid found within the cells of plants and other photosynthetic eukaryotes |
Light Dependent Reaction | The reaction taking place in the chloroplast in which the absorption of a photon leads to the formation of atp and nadph. |
Light Independent Reaction | The series of biochemical reactions in photosynthesis that do not require light to proceed, and ultimately produce organic molecules from carbon dioxide. |
Energy Pyramid | A graphical representation in the shape of a pyramid to show the feeding relationship of groups of organisms, and the flow of energy or biomass through the different trophic levels in a given ecosystem |
Producer | An autotrophic organism capable of producing complex organic compounds from simple inorganic molecules through the process of photosynthesis (using light energy) or through chemosynthesis (using chemical energy) |
Mitochondrion | A spherical or rod-shaped organelle with its own genome, and is responsible for the generation of most of the cell's supply of adenosine triphosphate through the process of cellular respiration |
