Photosynthesis Reaction

Question 1

What is the word equation for photosynthesis?

Answer 1

carbon dioxide + water —> oxygen + glucose

sunlight

Question 2

Write the balanced symbol equation for photosynthesis?

Answer 2

6CO2 + 6H2O —> C6H12O6 + 6O2

Question 3

What is an exothermic reaction?

Answer 3

Releases energy so energy is on the PRODUCT side of the equation

Question 4

What is an endothermic reaction?

Answer 4

Absorbs energy so it is on the REACTANT side of the equation

Question 5

What type of reaction is photosynthesis (exo/endothermic)?

Answer 5

Endothermic
Plants absorb energy from sunlight, which cones from the sun
Plants use this energy to turn carbon dioxide and water into oxygen and glucose

Question 6

How are Palisade cells adapted to their job?

Answer 6

• Near the top of the cell

- Contain lots of chloroplasts (absorb energy from sunlight for photosynthesis)

Question 7

What are the air spaces between spongy mesophyll cells meant for?

Answer 7

Allow carbon dioxide to diffuse in and oxygen to diffuse out.

Question 8

What is a guard cell’s function?

Answer 8

-Allow Gas Exchange to occur
-Controls water loss within the leaf
Day time: water flows into pair of guard cells - rigid
Night time: water flows out guard cells - less rigid
Prevents plant from wilting
