B8.1 - Photosynthesis (Finished)

Question 1

What is the word equation for photosynthesis?

Answer 1

Carbon dioxide + water -light> glucose + oxygen

Question 2

What is the symbol equation for photosynthesis?

Answer 2

6CO2 + 6H2O -light> C6H12O6 + 6O2

Question 3

What is the chemical equation for glucose?

Answer 3

C6H12O6

Question 4

What is photosynthesis?

Answer 4

A process using energy to change carbon dioxide and water into glucose and oxygen

Question 5

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

Answer 5

Endothermic

Question 6

Where does photosynthesis take place?

Answer 6

In chloroplasts

Question 7

What do chloroplasts have that allows for photosynthesis?

Answer 7

Chloroplasts contain pigments like chlorophyll allowing that absorb light. Energy is transferred from the environment to chloroplasts by light to carry out photosynthesis

Question 8

How is glucose produced in photosynthesis used at first?

Answer 8

Some of it is immediately used by the cells of the plant for respiration but a lot is converted to insoluble starch and stored

Question 9

What are some adaptions of leaves for photosynthesis?

Answer 9

• Leaves are broad giving a large surface area for light to fall on
• Leaves are thin so diffusion distances are short
• Leaves have veins bringing plenty of water in xylem to cells and removing products through phloem
• They have air spaces allowing allowing carbon dioxide to get to cells and oxygen to leave
• They have guard cells that open and close stomata to regulate gas exchange
• contain chloroplasts

Question 10

How do thin leaves help with photosynthesis?

Answer 10

Thin leaves allow for short diffusion distances for gases
