How do plants transport water, minerals, and food? Use the correct term and the direction of transport.
Xylem: transports water and minerals from the roots up to the rest of the plant
Phloem: transports food from the leaves down/away to the rest of the plant
Positive: increase until goal is reached (Ex: childbirth, blood clotting)
Negative: a response to reverse the initial change (ex: blood sugar, body temperature)
Name one plant hormone and its function.
Auxins: promote cell elongation and root growth (involved in phototropism)
Gibberellins: stimulate seed germination and stem growth
Cytokinins: promote cell division and leaf growth
