Term | Definition |
---|---|
photosynthesis | The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. |
respiration | A process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances. |
stomata | Tiny openings called stomata allow plants to exchange gases necessary for cellular processes, such as photosynthesis. |
guard cells | Cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata. To understand how they function, study the following figures. |
chlorophyll | The green pigment found in the chloroplasts of higher plants and in cells of photosynthetic microorganisms |
light dependent reaction | The series of biochemical reactions in photosynthesis that require light energy that is captured by light-absorbing pigments (such as chlorophyll) |
light independent reaction | dark reactions, of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. |
energy pyramid | The different levels represent different groups of organisms that might compose a food chain. |
producer | An autotrophic organism capable of producing complex organic compounds from simple inorganic molecules through the process of photosynthesis or through chemosynthesis Supplement. |
mitochondrion | 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 |
autotroph | An organism capable of synthesizing its own food from inorganic substances, using light or chemical energy. |
consumers | An organism 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 heterotroph. |
herbivore | often defined as any organism that eats only plants. |
omnivores | a kind of animal that eats either other animals or plants |
herterotrophs | 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. |
carnivores | an order of eutherian mammals that are mostly carnivorous and have teeth adapted for flesh eating. |
decomposers | organisms that break down dead or decaying organisms, and in doing so, they carry out the natural process of decomposition |
spongy layer | a layer of loosely packed and irregularly shaped chlorophyll-bearing cells that fills the part of a leaf between the palisade layer |
palisade | a 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. |
oxygen | A colorless, tasteless, oderless, gaseous element that abounds in the atmosphere. |
carbon dioxide | a colorless, odorless gas found in our atmosphere. |
glucose | the main type of sugar in the blood and is the major source of energy for the body's cells. |
products | chemical substance formed as a result of a chemical reaction; "a product of lime and nitric acid |
chloroplast | combination of two biological terms, plastid (an organelle in a plant cell), and chloros, which means green. |
