Uses of Glucose in Plants Flashcards

1️⃣ Familiarise yourself with the flashcards:

Look through all the flashcards to see what's on both sides.
Make sure you understand the information on each card. If something's unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

How do plants use glucose to get energy?

Plants use glucose in respiration to release energy.

Why do plants change some of the glucose they make into starch?

They change it into starch so they can store it for later when they cannot photosynthesise.

Why is starch better than glucose for storage in plant cells?

Starch is insoluble, so it does not dissolve in water and does not move out of the cells easily.

Where in a plant is stored starch often found?

It is often stored in leaves, roots and stems, for example in potato tubers.

Which substance do plants make from glucose to build strong cell walls?

They make cellulose from glucose to build strong cell walls.

How do plants use glucose and nitrate ions together?

They combine glucose with nitrate ions to make amino acids, which are then used to build proteins.

What type of food store do plants make from glucose in seeds and some fruits?

They make oils (fats) from glucose to act as a high-energy food store.

In what form is sugar often transported around the plant in the phloem?

Glucose is changed into sucrose, which is then transported in the phloem.
