How plants use glucose

Question 1

Name the five things that plants use glucose for?

Answer 1

• Respiration
• Making Cell Walls
• Making Proteins
• Storing it in seeds
• Storing as starch

Question 2

How do plants use glucose for respiration?

Answer 2

Respiration releases energy in the plant and enables it to convert the rest of the glucose into other useful substances to build new cells and grow.

Question 3

How do plants use glucose for making cell walls?

Answer 3

Glucose in converted into cellulose for making strong cell walls.

Question 4

How do plants use glucose to make proteins?

Answer 4

Glucose is combined with nitrate ions from the soil. This makes amino acids which are then made into proteins.

Question 5

How is glucose stored in seeds?

Answer 5

Glucose is converted into lipids for storing in seeds such as sunflower seeds which we use to extract cooking oil.

Question 6

How is glucose stored as starch?

Answer 6

Glucose is turned into starch and stored in the plant roots, stems and leaves, ready for use when photosynthesis isn’t happening (winter)

Question 7

Why is starch better for storing than glucose?

Answer 7

Starch is insoluble which makes it better for storing than glucose because a cell with lots of glucose would draw in lots of water and swell up
