Active recall
Quick check
Answer each question before opening the answer.
What do xylem and phloem transport, and in which direction?
Xylem carries water and minerals from roots to leaves (upwards). Phloem carries dissolved sugars/amino acids (translocation) in both directions.
How is a root hair cell adapted for its job?
It has a long, thin projection giving a large surface area for absorbing water and mineral ions.
