Companion cell

Question 21

What features are found in phloem

Answer 21

Companion cell with nucleus and vacuole, pore in sieve tube, cytoplasm, cellulose wall

Question 22

Name the two names relating to the cohesion tension model

Answer 22

Dixon and joly

Question 23

Name the first stage of water movement in vascular tissue

Answer 23

Water in soil

Question 24

Name the second stage of water movement in vascular tissue

Answer 24

Water enters root hairs via osmosis

Question 25

Name the third stage of water movement in vascular tissue

Answer 25

Water leaves root hairs and diffuses across ground tissue into xylem

Question 26

Name the fourth stage of water movement in vascular tissue

Answer 26

Upward movement agains gravity. Root pressure pushes and transpiration from above pulls the water molecules
