Photosynthesis
Do all plants, all animals, both, or neither do photosynthesis?
All Plants
Who does cellular respiration?
Both plants and animals/all living things
How many total atoms are present in a Carbon Dioxide molecule (CO2)?
Three Atoms (1 Carbon and 2 Oxygen atoms)
What cell organelle is like the brain of the cell?
Nucleus
Give and explain two reasons that support all life would end up dying without plants performing Photosynthesis.
1. Lack of Oxygen - Photosynthesis creates Oxygen for animals to breathe - Eventually Earth would run out of Oxygen
2. Starvation - Photosynthesis creates glucose which all animals need to survive (starts the food web).
The green pigment that absorbs and stores the energy of sunlight.
Chlorophyll
What are the REACTANTS of cellular respiration?
A compound made from hydrogen and oxygen.
Water
Which organelles do Photosynthesis and Cellular Respiration occur in? Specify the specific location for each reaction.
Photosynthesis occurs in Chloroplasts and Cellular Respiration occurs in the Mitochondria.
What EVIDENCE from class can you find that would show/support that Maple trees store Glucose in their trunks?
We tasted Maple Syrup in Lesson 1 and it was sweet like sugar/glucose
These are USED in photosynthesis, we call carbon dioxide, water, and sun energy the ....
Reactants or Inputs
How is Cellular Respiration related to Photosynthesis?
Cellular Respiration requires the products of Photosynthesis to work. The reactions are essentially the reverse of each other.
The entire chemical equation for Photosynthesis is:
6CO2 + 6H2O + Sunlight --> C6H12O6 + 6O2
How many of each atom are involved in the reaction?
The reaction uses 6 Carbon atoms, 12 Hydrogen atoms, and 18 Oxygen atoms (These numbers are how many enter the reaction and how many come out of the reaction)
What cell organelle is like a transportation network through the cell (like a road)?
Endoplasmic Reticulum (ER)
Which reaction occurs at a faster rate: Photosynthesis or Cellular Respiration? Must have at least one piece of EVIDENCE from class that would support your answer.
Photosynthesis. When we saw the data from the leaves in a closed system in the light, the Carbon Dioxide was DECREASING and the Oxygen was INCREASING overall, telling us that more Photosynthesis was occurring than Cellular Respiration as Cellular Respiration does the opposite.
What part of the plant transports water from the roots to the rest of the plant?
Xylem
Water, carbon dioxide, and ATP are ___________ of CELLULAR RESPIRATION
Products or outputs
Write a definition for the word stomata.
Microscopic pore like structure on leaf that allow for gases to enter and exit plant.
Name two organelles that plant cells have that animal cells do not have.
What does the data from leaves in a closed system with no light tell us? Remember with limited light, the oxygen level decreases and Carbon Dioxide level increased.
Plants cannot perform Photosynthesis in the dark. We see the Carbon Dioxide level decreasing and Oxygen level increasing (opposite of Photosynthesis) revealing that the plants are performing Cellular Respiration
When would photosynthesis NOT be able to occur in a plant? Give at least 3 ideas.
At night, in a dark room, in the winter, etc.
What is the type of energy MADE in cellular respiration?
ATP (which is a type of chemical energy)
Write the Chemical Formula for Glucose
C6H12O6
Water filled __________ stored water for plants to use during photosynthesis.
Vacuole
Carbon Dioxide is a greenhouse gas which contributes to global warming. Hypothetically, how would increasing the amount of plants affect this issue? Explain why.
Increasing the number of plants would HELP counteract global warming. Plants do Photosynthesis much faster than Cellular Respiration so overall use much more Carbon Dioxide than they would make; therefore, increasing the amount of plants would lower the amount of Carbon dioxide and greenhouse gases in atmosphere over time.
