Photo-synthesis
Plants use energy from this source to start the process of photosynthesis.
What is the sun? (or sunlight, or light energy)
Cellular respiration breaks down glucose to release this useful output for the cell.
What is Energy (or ATP)?
Often called the "powerhouse" of the cell, this organelle is where cellular respiration happens.
What is the Mitochondria?
The waste product of photosynthesis (Oxygen) becomes the reactant for this process.
What is Cellular Respiration?
This gas is taken in by leaves from the atmosphere to build sugar.
What is carbon dioxide (CO2)
This gas is a required reactant for aerobic cellular respiration to occur.
What is Oxygen?
This organelle is the site of photosynthesis and is found in plant cells but not animal cells.
What is the Chloroplast?
Bromothymol Blue (BTB) is a chemical indicator that changes color to show the presence of this specific gas.
What is Carbon Dioxide?
This is the pigment inside chloroplasts that makes photosynthesis happen.
What is chlorophyll?
This gas is produced as a waste product during respiration and is exhaled by animals.
What is Carbon Dioxide?
These tiny openings on the underside of a leaf allow gases like $CO_2$ and Oxygen to enter and exit.
What are Stomata?
If you blow through a straw into a beaker of blue BTB, the liquid turns yellow because you are adding this gas.
What is Carbon Dioxide?
Photosynthesis produces this gas, which humans and animals need to breathe.
What is oxygen (O2)?
While photosynthesis occurs only in plants (and some bacteria/algae), cellular respiration occurs in these types of organisms.
What are all living things (or plants AND animals)?
Besides chloroplasts, this stiff outer layer is another structure found in plant cells but not animal cells.
What is the Cell Wall?
A snail is placed in a test tube with blue BTB and left overnight in the dark. The next day, the BTB is yellow. This is because the snail performed this process.
What is Cellular Respiration?
The main goal of photosynthesis is to produce this specific type of sugar for food and growth.
What is glucose?
This is the three-letter name for the chemical energy molecule created during respiration.
What is ATP?
These specialized cells surround the stomata and control their opening and closing to prevent water loss.
What are Guard Cells?
An Elodea water plant is placed in a test tube of yellow BTB and put under a bright light. After a few hours, the water turns blue because the plant removed the CO2 to perform this process.
