Photosynth/Cell Resp
Photosynthesis and Cellular Respiration
| Question | Answer |
|---|---|
| photosynthesis | a type of autotrophic nutrition in which green plants use the energy of sunlight to convert carbon dioxide and water into glucose |
| chloroplast | a cell organelle found in plant cells that contains chlorophyll and functions in photosynthesis |
| chlorophyll | a green pigment in plant cells that absorbs sunlight and makes possible certain aspects of the photosynthetic process |
| light energy | energy from the sun |
| carbohydrate | an organic compound made of carbon, hydrogen, and oxygen. |
| producer | any autotrophic organism capable of trapping light energy and converting it to the chemical bond energy of food |
| Which organisms form the basis of the food chain? | producers/autotrophs |
| autotroph | an organism capable of carrying on photosynthesis -"self feeder" |
| consumer | any heterotrophic animal organism -must consume food for energy |
| heterotroph | an organism that typically carries on heterotrophic nutrition -must consume food for energy |
| heterotrophic nutrition | a type of nutrition in which organisms must obtain their foods from outside sources of organic nutrients (food) |
| food chain | series of nutritional relationships in which food energy is passed from producer to herbivore to carnivore to decomposer |
| main source of energy for most organisms on the Earth | the sun |
| autotrophic nutrition | a type of nutrition in which organisms manufacture their own organic foods (glucose) from inorganic raw materials (water, carbon dioxide, light energy) -photosynthesis |
| stomate | a small opening that penetrate the lower part of a leaf where carbon dioxide, water, and oxygen are absorbed and released |
| guard cell | one of a pair of cells that surround the leaf stomate and regulate its size |
| glucose | a simple sugar made in photosynthesis and used by both plants and animals as a fuel in the process of respiration |
| adenosine triphosphate (ATP) | an organic molecule that stores energy in the form of chemical bond energy for the cell |
| In which organelle is ATP produced? | mitochondria |
| mitochondrion | a cell organelle that contains the enzymes necessary for aerobic cellular respiration -makes ATP |
| aerobic respiration | a type of respiration where energy is released using oxygen |
| anaerobic respiration | a type of respiration in which energy |
