Question
Chapter 39, Problem 3TY
Summary Introduction
Introduction: There are many ways by which the plants prevent water loss. The development of mechanisms and structure is the method to cope up with the evaporative loss of water. The excessive water loss from the plant body can result in the stunted growth.

Animals typically use fats in adipose tissues for longterm energy storage, whereas plants use starch in roots. How do animals benefit from using fat? How do plants benefit from using starch? Name two plants that storeenergy for many years. How long is long-term storage for these species? What two plant parts often use fats and why? Storage tissue in enlarged roots is vascularized. How is that important to the plant?
