Q

Why are plants essential for life on Earth

A

Plants provide many other organisms with raw materials, if there were no plants, the animals that depended on plants would perish, leaving us with no food or oxygen

50
Q

What do plants use glucose for?

A

Respiration, make new chemicals, and storage

51
Q

When there is excess glucose, it is converted into starch and stored for later, how do we test for the presents of starch?

A

We use Iodine solution. If starch is present, the solution will turn blue/black. If starch is absent, it will remain orange/brown
