Lab/Activity Review
The bubbles in the lab are _______ gas.
Oxygen
(T/F) Only plants do photosynthesis
FALSE; plankton + bacteria
Define photosynthesis.
chemical reaction used by plants, bacteria, and plankton to make their own food to grow
We give plants ______. Plants give us ______.
carbon dioxide; oxygen
Should we drink chlorophyll water? Why or why not?
NO --> No scientifically proven benefits
Oxygen and glucose are signs that _________ is happening.
photosynthesis
(T/F) Plants do photosynthesis to release oxygen for us.
FALSE - They do it for food/to grow.
Define chlorophyll.
green pigment in plants that absorbs sunlight
Explain why a plant and mouse will live together in a bell jar.
Chlorophyll capture _____ ________ and photosynthesis happens in the _____________
sun energy; chloroplast
The bubbles in the breathing leaves lab and the water weed lab were made because...
plant released oxygen
Photosynthesis is a __________ __________.
Chemical reaction
What are the reactants of photosynthesis?
sun + water + carbon dioxide
Explain why the sun is NOT a source of matter (gives atoms) for plants.
Sun provides energy; not atoms
Diagram the cycle of matter with the candle, mouse, and plant
candle + mouse --> co2 --> plant --> O2 --> candle + mouse
Why did we learn about plankton in a photosynthesis unit?
They do phtosynthesis!
Photosynthesis happens in the plant's...
Products of photosynthesis?
Please explain how Michael Jordan (the pumpkin) grew to be so big and heavy.
Use: photosynthesis, water, carbon dioxide, glucose, nutrients
He was watered 12+ times a day! Converted water atoms into glucose for growth via photosynthesis. He gained nutrient atoms from the soil as well!
Write the full chemical reaction for photosynthesis. Label what the sun provides.
water + carbon dioxide --> glucose + oxygen
sun provides energy for chem rxn
In the lab, we measured __________ instead of ___________ because glucose is....
oxygen; glucose; inside the plant
List 3 reasons plants/photosynthesis are important to learn about.
1. We eat plants/use them for medicine/building materials
2. We get oxygen from plants/plankton
3. Make up base of food chain/web (everything eats them)
Why do plants do photosynthesis? (use the words matter, atoms, and glucose)
Plants convert water and carbon dioxide atoms into food called sugar or glucose. Plants can use the sugar to grow and gain matter/mass
What does the cycle of matter refer to for photosynthesis?
Plants do photosynthesis and release oxygen. We breathe in oxygen and breathe out carbon dioxide. Plants can use carbon dioxide to continue to do photosynthesis.
Oxygen is a ______ product, meaning...
waste; byproduct meaning plants don't do photosynthesis to create oxygen
