(1) absorbing water and nutrients from the soil; (2) holding the plant to the soil; (3) food storage.
What is the outermost layer of a leaf called? Where else could you find something with the same name?
The epidermis; your skin!
What is the role of the stomata?
Controlling the amount of water and air that enters/exits a plant cell.
What is the process of photosynthesis? What is the role of it?
Converting carbon dioxide, sunlight, water and nutrients into glucose/elaborated sap; to feed the plant.
Where does photosynthesis take place?
In the leaves; specifically the chlorplasts.
How does glucose get transported through the plant?
Through the phloem to the stems and roots.
What are the differences between xylem and phloem?
xylem: one-way, no end walls, for water and minerals; phloem: two-ways, end walls, for food and water.
What does the chloroplast need to produce food?
Carbon dioxide, water, solar energy, nutrients/minerals.
How do plants obtain carbon dioxide?
From the air through their stomata.
