By now you know quite a lot about how plants are designed - that's their structure.
The roots are underground and have the job of holding the plant firmly in the soil as well as drawing up the water and mineral nutrients that the plant needs to grow and be healthy.
The leaves are the plant's 'food factory', making sugar from simple ingredients like air, water and sunshine!
The stem (or stalk) transports water and food around the plant and makes sure that the leaves are held up towards the sun.
The flower is where the 'baby plants' are made (how the plant reproduces itself), using insects and wind to help this work.
So, in the following questions you will be testing yourself on your understanding of which part of a plant is which and what the different parts do for the plant as a whole.
Sound OK? Let's get going!
