N5 2.5 Plant Transport

How do water and minerals enter a plant?

• through the root hairs by osmosis

• through the stomata by osmosis

• through the xylem by osmosis

• through the phloem by osmosis

Which of the following shows the pathway of water and minerals as it moves through a plant?

(a)  

• stomata --> root hair cell --> xylem

• xylem --> stomata --> root hair cell

• root hair cell --> xylem --> stomata

root hairs increase the ​ (a)   of roots to enable the plant to absorb water quickly.

• surface area
• root thickness
• xylem length

Which answer is a description of xylem vessels?

• Living tissues in plants that transport sugars

• Tiny pores on the leaf epidermis that allow gas exchange

• Structures that increase the surface area for osmosis

• Dead, hollow tubes with lignin, that transport water and minerals

Where is the stoma located?

Which is an example of a guard cell?
