Chapter 4: Transportation in Plants
What you need to learn in this chapter
In this chapter, we will be learning about transportation in plants. We will understand the importance of transportation in plants and how it is achieved through vascular tissues. We will explore the structure of xylem and tracheids and how they facilitate the transport of water and mineral salts. We will also study the factors involved in the pathway of water and mineral salts from the soil to the leaves, including root pressure, capillary action, and transpiration pull. Additionally, we will learn about guttation in plants. We will also delve into the concept of translocation and its significance in plants. Lastly, we will define phytoremediation and explore its applications in our daily lives.
