living organisms

Introduction

For biological processes to occur in the body, efficient transport of essential
materials from one place to another is crucial. In this chapter, you will learn
about mechanism of transporting materials in living organisms, which are
diffusion, osmosis, and mass flow. The competences developed will enable you to
understand how substances move across cell membranes and through organisms.
You will also be able to support the survival of living things such as plants by
ensuring efficient supply of the materials they need.

Think of materials from the organism to the

Transport of materials is the
movement of materials either from to different parts of the body for
the environment into the organisms assimilation and storage. Then, the by-
or from one part of the organism to products and waste are excreted from
another. It can also be the movement the organisms to the environment.
