Question 4

Which of the following is a function of root hairs in the root system?

Question 5

A plant is observed to have a taproot system. Which of the following is a likely advantage of this root type in a drought-prone environment?

Accepted Answer

Taproots can reach deeper water sources underground.

Question 6
