Question
Chapter 28, Problem 2TYK
Summary Introduction
Introduction:
The plant organs, such as leaves and young shoots are covered with the thin layer of a waxy substance called the cuticle. The cuticle is composed of the cutin, which is hydrophobic in nature. The cuticle does not allow the passage of the water and gases through it.

The seeds of the plants never touch the soil on the ground far below. The seed breaks open and rodts grow to support the plant as it grows. Stems begin to dimb upwards. Leaves spread to gather the light at the top of the tree. The heavy rain and humid air of Florida means that the plants can get all of the wwater they need right wihene they grow. These plants are commonly called "air plants." 19 What important process within air plants is most likely different compared to plants that live on the ground? A. making food B. growing leaves C. reproducing D. getting nutrients 20 "Spanish moss" is a common type of air plant that grows in Florida. However, the common name is not correct.
