What is the main purpose of the roots? | to absorb and take up water and minerals from soil, to anchor the plant in the ground |
Why do plants have root hairs? | to increase the surface area by which to absorb more water and minerals |
What does the xylem carry? | water and minerals from the roots throughout the plant |
What does the phloem carry? | food to all parts of the plant |
Where is glucose made? | in the leaves/chloroplasts |
What is the purpose of the guard cells? | to open and close the stomata |
What is the stomata? | to allow water, carbon dioxide, and oxygen to enter and exit a leaf |
