Plant Biology Exam1

Front 1

1. What is one major difference between plants and most animals?

Back 1

plants are rooted, and therefore stationary, whilst most animals are mobile.

Front 2

1. Name two products that we use that come from plants

Back 2

Oxygen
Wood
Paper
Food
etc.

Front 3

1.Is our life on this planet possible without plants?

Back 3

NO!

Front 4

1.Justify why life isn't possible without plants?

Back 4

We would be unable to berath without the oxygen that plants prodcue as a bi-product of photosynthesis. Also, plants are the base of almost all food chains, and certainly the oen that support human life.
