Which of the following traits of land plants allows them to grow in height?

alternation of generations

waxy cuticle

tracheids

sporopollenin

Trachieds

Explanation:

Trachieds are the cells in the xylem - vessels in plants that allow for transportation of water. Trachieds are not perforated i. e they do not have pits like phloem does. As a result of not being perforated trachieds make the xylem a very strong tissue which can withstand the force of water and hold the land plant up.
