The purpose of this module is to enable students to be known more about the sources of industrial plants that include cyanobacteria, algae, fungi and angiosperm. In addition, fibers, dyes, latex, oils, and food and species those could be obtained from plants also could be learned by this module.

Plants are essential to life on earth; they produce the oxygen we breathe through photosynthesis and provide much of the food we eat. Some species provide medicines and promote healing; others are used for insect control or to conserve water. Plants with dense root systems prevent soil erosion and those with brightly colored flowers attract pollinators. Plants have been used to control body functions and fertility, to poison, and to make clothing, paper and rubber. Therefore, the economic plants may be defined as being useful directly, as in food, or indirectly, as products we use or that enhance the environment.
