B2 - Plant Anatomy

Question 1

What is the term used to describe the transfer of water in plants?

Answer 1

Osmosis

Question 2

How does Osmosis work?

Answer 2

Substances move from a high concentration to a low concentration along/against a concentration gradient

Question 3

How does water enter a plant?

Answer 3

Via the root hair cells (osmosis)

Question 4

What makes root hair cells suitable for absorbing water?

Answer 4

They have a large (hammer-like) structure that has a large surface area and volume capacity

Question 5

How does water move from the root hair cells into the other plant cells (a.k.a the stem etc)

Answer 5

Water moves from cell to cell in the roots

It then enters the Xylem tissue, water then moves up the vessel into the leaves

Water is then moved from the Xylem tissue into air spaces in leafs

Question 6

Where does the water go/what is it used for once it reaches the leaf tissue?

Answer 6

Some is evaporated (transpiration) at the Stoma

Some is used in photosynthesis to make sugars
