| Term | Definition |
|---|---|
| Photsynthesis | Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. |
| Respiration | the sum total of the physical and chemical processes in an organism by which oxygen is conveyed to tissues and cells, and the oxidation products, carbon dioxide and water, are given off. |
| Stomata | allow plants to exchange gases necessary for cellular processes such as photosynthesis |
| Guard Cells | One of the paired cells in the epidermis of a plant that control the opening and closing of a stoma of a leaf. |
| 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 |
| Chloroplast | is the combination of two biological terms, plastid (an organelle in a plant cell), and chloros, which means green. |
| Light dependent reaction | The series of biochemical reactions in photosynthesis that require light energy that is captured by light-absorbing pigments (such as chlorophyll) to be converted into chemical energy in the form of ATP |
| Light independent react. | light-independent reactions, or dark reactions, of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. |
| Energy pyramid | is a graphical model of energy flow in a community. |
| 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) |
| Mitochondria | Turning on the Powerhouse. Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell. |
| Autotrophs | An organism capable of synthesizing its own food from inorganic substances, using light or chemical |
| Consumer | that generally obtains food by feeding on other organisms or organic matter due to lack of the ability to manufacture own food from inorganic sources; a |
| Herbivore | A herbivore is often defined as any organism that eats only plants. |
| Omnivores | An omnivore is a kind of animal that eats either other animals or plants. |
| Heterotrophs | An organism that cannot manufacture its own food and instead obtains its food and energy by taking in organic substances, usually plant or animal matter. All animals, protozoans, fungi, and most bacteria are |
| Carnivores | An animal or plant (particularly insect- and invertebrate-eating plants) that requires a staple diet consisting mainly or exclusively of animal tissue through predation or scavenging. |
| Decomposers | are organisms that break down dead or decaying organisms, and in doing so, they carry out the natural process of decomposition. Like herbivores and predators, decomposers are heterotrophic, meaning that they use organic substrates to get their energy, car |
| Spongy layer | a layer of loosely packed and irregularly shaped chlorophyll-bearing cells that fills the part of a leaf between the palisade layer and the lower epidermis -- called also spongy parenchyma, spongy tissue. |
| Palisade layer | layer of columnar cells rich in chloroplasts found beneath the upper epidermis of foliage leaves. — |
| Raw Materials | are materials or substances used in the primary production or manufacturing of goods. Raw materials are often referred to as commodities, which are bought and sold on commodities exchanges worldwide. |
