Process Of Photosynthesis

Question 1

What is the word and chemical equation for photosynthesis?

Answer 1

Word : Carbon dioxide + water -(sunlight energy)- glucose + oxygen

Chemical : 6CO2 + 6H2O -(sunlight energy)- C6H12O6 + 6O2

Question 2

Raw materials needed for photosynthesis.

Answer 2

Carbon Dioxide
Radiant Energy (sunlight)
Chlorophyll
Enzymes

Question 3

Products of photosynthesis

Answer 3

Glucose

Oxygen (by-product)

Question 4

Importance of photosynthesis

Answer 4

Plant survival -
(plants are used in structures/ building materials, the production of fossil fuels, provide habitats, Medicine extracts)
Atmospheric gasses kept stable (production of oxygen)

Question 5

Photosynthesis stages

Answer 5

2 stages :

Sunlight -
( sunlight with the chlorophyll help in converting light energy into chemical energy)
No sunlight -
(Chemical energy synthesises glucose)

Question 6

Chlorophyll

Answer 6

Found in chloroplasts.

• Grana (thyckaloids stacked on top of each other connected by middle lamella)
• Stroma (aqueous space)
• inner membrane
• Outer membrane

Question 7

What happens to glucose?

Answer 7

• Used in respiration
• Changed to starch and stored
• Makes cellulose walls
  Converted into :
• amino acids, later converted into proteins
• Fats and oils
