| Movement of water across a semi-permeable membrane is called | osmosis | The process by which the energy stored in a sugar is released is called | respiration |
| If the release of energy stored in a sugar occurs in the absence of oxygen, the resulting products are either ethanol or lactate, and the process is called | fermentation | All of these reactions are catalyzed by proteins called | enzymes |
| The main transporter of energy within the plant is a small molecule made of a nucleotide and phosphorus called | ATP | The green pigment which captures light energy is called | chlorophyll |
| One of the photosynthetic systems which is specialized for desert plants which cannot keep their stomata open during the heat of the day is called | CAM | The first form of carbon fixation that was discovered occurred when CO2 combines with ribulose bis phosphate to form PGA is called | C3 |
| The second form of carbon fixation that was discovered occurs when CO2 combines to form malate which is then transported to another part of the leaf is called | C4 | The part of the leaf in which the malate in the previous question is transported to is called the | bundle sheath |
| The word that refers to chemicals made of carbon backbones | organics | The enzyme that begins the process of photosynthesis and is the most abundant enzyme on the face of the earth | Rubisco |
| An organic compound synthesized by the plant and which is trans-located to another part of the plant, where, in uM concentration it elicits a response is called a | hormone | The first of these to be discovered causes meristems to bend and is called | auxin |
| Another of these, the discovered in fungi, cause plant elongation is called | gibberellin | Maturation of fruits and plant organs is promoted by | ethylene |
| Response of a plant to light is called | phototropism | Response of a plant to gravity is called | gravitropism |
