Why do plants have roots?
Key Knowledge:
Plants have roots for specific
reasons
Roots are integral to the survival
- f a plant
Roots anchor plant into the
ground
Roots absorb water and nutrients Roots can adapt to their
environment
Key Vocabulary:

Thought Task
Where are the roots of these plants? What do you know about roots?
SLIDE 8
Investigating roots:
These plants have been dug out of the ground. Look at their roots.
SLIDE 9
Investigating roots:
Do you think it was easy to dig them up? Why not?
SLIDE 10
Investigating roots:
What does this tell us about roots?
SLIDE 11
Investigating roots:
If you cut the roots of a plant after digging it up they are usually wet.

Workbooks page 11 Answer the questions using the sentence stems shown
Roots are difficult to dig up because ……. Roots usually feel _________, this is because …….
SLIDE 14
Investigating roots:
Why was the plant difficult to dig up? The plant was difficult to dig up because the roots were holding it tightly into the soil and also holding the soil really close to the plant. We call this anchoring the plant into the ground and it is one of the functions of the roots. Why were the roots wet when they were cut? The roots were wet when they were cut because the other function of roots is to absorb and store water from the soil.
SLIDE 15
Do you think all roots look the same?
Longer roots can absorb water from deeper underground Tuberous roots can store water for longer periods of time More fibrous roots can search for water over larger distances Roots closer to the surface can absorb surface water in addition to water underground
Why might these roots be different?
