Photosynthesis
What is the purpose of photosynthesis?
To create food molecules for the plant!
What two ways do plants get energy?
Light energy & Cellular respiration.
What are the inputs for photosynthesis?
Carbon Dioxide, Water, Energy.
What is the start of the carbon cycle?
There is no official start or end, hence the word cycle!!
What two things are needed for something to be considered matter?
Mass and volume.
Do plants photosynthesize all the time?
No, if there is no light energy than they do not do photosynthesis.
What is the purpose of sap for trees?
To provide the tree with glucose/energy for the winter months.
What are the outputs of photosynthesis?
Oxygen and water vapor.
What is a food chain?
The relationship of the transfer of food molecules (what eats what).
Can matter be created or destroyed?
No! It is transformed!
What is the Stomata?
The part of the plants leave that opens and closes to capture and release gases.
Where do plants get energy from when it's dark outside?
Cellular resperation!
What are the inputs for cellular resperation?
Oxygen, glucose.
Describe the carbon cycle.
The carbon cycle is how carbon moves throughout our Earth.
How can matter move from plant to animal?
When an animal eats the plant, the food molecules (the matter) are transformed inside the animal.
When carbon dioxide, water, and energy all come together during photosynthesis, what is created?
Glucose/food molecules!
What food molecule is produced in plants as the "for later" energy?
Starch!
What are the outputs of cellular resperation?
Carbon Dioxide, water vapor, energy.
What is the law of conservation of matter?
Matter cannot be created or destroyed, just transformed.
Is energy matter?
No!
Where in the plant cell does photosynthesis occur?
Chloroplast
This process releases carbon dioxide back into the atmosphere when organisms break down glucose for energy.
Cellular respiration.
For what process is starch an input?
Cellular respiration!
Does energy cycle?
No. Energy flows, not cycles.
What is a decomposers role in matter cycling?
Breaks down organic material, helping release carbon back to the Earth/atmosphere.
