Photosynthesis Reaction

Question 1

What is the word equation for photosynthesis?

Answer 1

Carbon dioxide + water —> Oxygen + glucose

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/endo)?

Answer 5

Endothermic -
Plants absorb energy from sunlight, which comes 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 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 a pair of guard cells - rigid
  Night time: water flows out guard cells - less rigid

Prevents plants from wilting
