Which organs make up a flowering plant’s vegetative apparatus?
Roots, stem, and leaves.
What do roots absorb from soil?
Water and mineral ions.
How do fine roots and root hairs near their tips affect soil contact?
They greatly increase contact with soil water and minerals.
What is a mycorrhiza?
An intimate, lasting, mutually beneficial association between a plant root and a fungus of a different species.
Which pigments in chloroplast thylakoids capture photons for photosynthesis?
Chlorophyll pigments.
Where does raw sap form, and what does it contain?
It forms in roots from absorbed water and mineral salts.
Which vascular tissue transports raw sap?
Xylem.
What does the hydrophobic, lipid-rich cuticle on outer epidermal surfaces limit?
Dehydration.
How do stomata respond to drought to limit water loss?
They close.
What surface advantage do flattened leaf blades provide?
A large surface for capturing light.
