Photosynthesis
Question | Answer |
---|---|
Sun's Radiant Energy is a form of what type of energy | Kinetic Energy |
Sun's Radiant Energy travels by ... | Waves/Particles |
Sun's Radiant Energy can move through... | Space |
What type of energy is VITAL for plants to make their own food? | Visble Light Energy |
Why are plants green? | Chloroplasts that have Chlorophyll -- Chlorophyll absorbs most of the colors in the visible light spectrum EXCEPT for green which is reflected. |
3 Reactants Needed for a Green Plant to make it's own food... | 1. Light Energy from the Sun 2. Water & Soil Nutrients 3. Carbon Dioxide |
The food making process is called ... | Photosynthesis |
When does Photosynthesis occur? | Daylight hours ONLY! |
Light Energy only occurs in... | Green Leaves |
What is the function of the Xylem? | Transport Water & Nutrients from roots to the leaves |
What is the function of the Phloem? | Transport food from the leaves to the rest of the plant. |
What type of plants are the Xylem & Phloem found in? | Vascular Plants |
Where does CO2 enter into the leave? | Stoma or Stomata |
What do green plants do with CO2 | They remove it from the atmosphere |
What is the equation for Photosynthesis? | 6CO2 + 6H2O -- (Light Energy) --> C6H12O6 + 6O2 |
What can plants do with Glucose (Sugar)? | Plants can turn Glucose into starch. They use it for storage & fuel! |
Oxygen (O2) moves out of the plant through which part ? | The Stomata |
What happens to O2 after Photosynthesis? | It is put back into the atmosphere |
Law of Conservation Mass | The atoms on both sides of the equation must be equal! No Mass is created OR destroyed! (Count the atoms/elements on each side of the Photosynthesis equation -- There should be 6 C , 12 H & 18 O on both sides! |
What is Respiration? | This unlocks the energy that is produced by Photosynthesis. |
What does Respiration do? | Creates energy for growth, reproduction, and other life processes. |
When does Respiration happen? | This process happens both DAY & NIGHT! |
What is the equation for Respiration? | C6H12O6 + 6O2 ---> 6CO2 + 6H2O + Energy Light is NOT needed! Opposite of Photosynthesis formula! |
