Plants have adaptations to help them survive in harsh environments; Some live in a forests where plants have to find a way to get the sunlight they require, some live in an aquatic environments where there is an abundance of water, and some live in desert environments where it is dry and very hot. These plants have different adaptations such as leaf size, leaf surface, stem size, and their stress level. In this lab, we will be discussing plants from 3 different regions; forest, aquatic, and desert, and describe some of their adaptations that allows them to live and prosper. Evenezer Tekie
