You may know the different parts of a plant but did you know they all have a function, or job? Leaves, for example, catch sunlight and turn it into food, and roots suck up water and nutrients from the ground. The Venus Flytrap is one of the most unusual plants in the world. Unlike the vast majority of plants, the Venus Flytrap is meat-eating - it traps and digests insects! Despite this, the Venus Flytrap still behaves like other plants - it can make food from sunlight falling on its leaves - and has the same parts as other plants.

Stems also provide support for plants and help leaves to reach the sunlight
3. Which parts of a plant anchor it to the ground and also absorb water from the soil?
[ ] Stem
[ ] Flowers
[x] Roots
[ ] Leaves
Nutrients are also absorbed from the soil by roots
4. Flowers play a role in which of a plant's life processes?
[ ] Plant nutrition
[ ] Plant excretion
[x] Plant reproduction
[ ] Plant respiration
Flowers are where pollen is transferred, eggs are fertilized and seeds and fruits develop
5. What do we call a tree's stem?
[ ] Its tap root
[x] Its trunk
[ ] Its bud
[ ] Its seed pod
Tree trunks are much harder than the stems of other types of plants - that's because they are made of wood!

9. What do buds become?
[ ] Leaves

[ ] Branches
[x] All of the above
Did you know that Brussels sprouts are actually buds?
10. Which part of a flower produces pollen grains?
[ ] The ovary
