plant
What are the three things plants need to survive?
Food (sunlight)
Water
Oxygen
What are the reactants of Photosynthesis?
Sunlight
Carbon Dioxide
Water
How is the bottom layer of epidermal cells designed to aid photosynthesis ?
Contains stomata that allows gases to pass through the lead
Describe what happens in step 2 of photosynthesis
Carbon Dioxide is converted into sugar molecules
Sugar used as energy or stored for later
Where does cellular respiration take place?
Mitochondria
What are the two processes plants use to get food and energy?
Photosynthesis
Cellular Respiration
What are the products of Photosynthesis?
Glucose (sugar / food)
Oxygen
What is the difference between Palisade cells and spongy cells?
Palisade cells are located at the top of the cell and aid in absorbing sunlight
Spongy cells are located at the bottom and aid in gaseous exchange
What chemical is responsible for absorbing / reflecting sunlight?
Chlorophyll
The energy created in cellular respiration is called what?
ATP
What are the two examples of vascular tissue that we discussed?
Xylem
Phloem
What is the cuticle and how does it aid Photosynthesis?
A waxy covering above the top layer of epidermal cells
Retains water
What three gases are involved in photosynthesis?
Water vapor
Oxygen
Carbon Dioxide
Why is photosynthesis important for humans?
Produces the majority of oxygen in the atmosphere
What are the reactants of Cellular Respiration?
Glucose
Oxygen
How does Xylem facilitate photosynthesis / cellular respiration?
By distributing water throughout the plant
What do mesophyll cells contain that allows photosynthesis to occur?
Chloroplasts
What organelle does photosynthesis take place in?
Chloroplasts
Why is photosynthesis important for humans?
Produces the majority of oxygen in the atmosphere
What are the products of Cellular Respiration?
Carbon Dioxide
Water
ATP
How does Phloem facilitate photosynthesis / cellular respiration?
By distributing food throughout the plant
How does the top layer of epidermal cells aid photosynthesis?
Thin / flat cells that are transparent enough to allow sunlight to pass through
Describe what happens in step 1 of photosynthesis
Light energy is absorbed and transferred to other molecules
Breaks water molecules
Releases oxygen into atmosphere
What is the purpose of cellular respiration?
To convert food into usable energy
What is the chemical equation for photosynthesis?
Sunlight + CO2 + H2O
=
C6H12O6 + O2
