how plants use glucose

Question 1

uses of glucose in plants

Answer 1

-Used for respiration (both aerobic and anaerobic)

-Converted into insoluble starch for storage in the stems, leaves and roots

-Used to produce fat or oil for storage (especially in seeds)

-Used to produce cellulose, which strengthens the cell wall

-Combined with nitrate ions absorbed from the soil to produce amino acids for protein synthesis

Question 2

what is starch used for in the plant

Answer 2

stored in cells of leaves - provides an energy store

• many plants produce tubers and bulbs that are stored with starch to help them survive the winter

-many humans take advantage of this as they are found as vedgetables

Question 3

how can plants store large amounts of starch

Answer 3

Starch is a good storage molecule because it’s insoluble, so it doesn’t affect the osmotic balance of the cell, and its structure allows for compact storage.

Question 4

explain why pitcher plants, sundews and Venus fly traps are often found growing in bogs globally and environment where often not many other plants can survive (6 marks)

Question 5

Describe where you might find starch in a plant. (4)

Answer 5

leaves, stems, roots, storage organs
