Photosynthesis
Rubarts Quiz Practice
| Sun’s energy is | kinetic energy |
| Sun’s energy can be | absorbed, transmitted, or reflected |
| What energy do plants use to make their own food? | visible light energy |
| What pigment is found in chloroplasts? | chlorophyll. |
| What color of light do green plants reflect? | green |
| What are the colors in the visible light spectrum? | Red, Orange, Yellow, Green, Blue, Indigo, Violet |
| What acronym do we use to remember the colors of light? | ROY G.BIV |
| What 3 reactants are needed for a plant to make its own food? | Energy from the Sun, Water, Carbon dioxide(CO2) |
| The plant’s food-making process is called | photosynthesis. |
| What does chlorophyll do? | Allows the plant to absorb the light energy. |
| Where does photosynthesis occur? | In green leaves |
| Water and nutrients move from the roots to the leaves through | the Xylem |
| Food (sugar) moves from the leaves to the rest of the plant through | the Phloem |
| Where are xylem and phloem found? | In vascular plants, like most trees and flowering plants |
| Symbol for Carbon Dioxide | CO2 |
| What is the structure of the leaf that allows carbon dioxide to enter the leaf and oxygen to leave the leaf? | The stoma (stomata) |
| What do guard cells control? | The opening and closing of the stoma. |
| How do green plants affect the atmosphere? | They remove tons of CO2 from the atmosphere in the process of photosynthesis |
| What do we call the materials needed to cause a chemical reaction? | Reactants |
| What do we call materials created by a chemical reaction? | Products |
| What does the plant use sugar (glucose) for? | Glucose is a source of fuel, and starches produced from glucose are used to make cell walls. |
| What are the products of photosynthesis? | Glucose (C6H12O6) and oxygen (O2 ) |
| What does photosynthesis put into the air? | tons of oxygen |
| Mass in an isolated system is neither created nor destroyed by a chemical reaction. | Law of Conservation of Mass |
| The mass of the products must equal the mass of the reactants and the number of atoms on both sides of the arrow must be equal in a | balanced equation |
| Photosynthesis Equation: | 6CO2 + 6H2O + Energy from the sun → C6H12O6 + 6O2 |
| How do green plants unlock the energy in glucose? | Respiration |
| This creates energy for growth, reproduction, and other life processes | Respiration |
| When does respiration happen? | Both day and night |
| Respiration Equation | C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy |
| How are photosynthesis and cellular respiration the same? | They contain the same compounds - water, carbon dioxide, glucose and oxygen. They both involve energy |
| How are photosynthesis and cellular respiration different? | One is the reverse of the other. The products of one are the reactants of the other. Photosynthesis uses energy (from the Sun), while cellular respiration creates energy (for the plant). Cellular respiration happens day and night. |
| Plants turn glucose into this | starch |
| Photosynthesis is a process only seen in _________. | Plants |
