CBSE NCERT Solutions For Class 10 Science Chapter 6: Life Processes
In this chapter, you will learn about the various maintenance processes in living organisms, which help us differentiate between what is alive and what is not. From visible growth in living organisms to molecular movements that cannot be seen with naked eyes, there are many processes that help plants and animals to stay alive. All living organisms are well-organized structures comprising of cells, tissues, and other components. These living structures are likely to collapse over time due to environmental effects.

We tend to associate movement with life. While some movements are results of growth (like in plants), others are not connected to growth (like a cat running). But all movements in plants and animals are basically responses to changes in the environment. Living organisms also tend to make the best of changes in the environment through controlled movement. For example, plants tend to grow towards sunlight so that they can use sunlight for photosynthesis.
Movement is a crucial life process in all living organisms for their survival. In this chapter, you will learn about the systems in living organisms providing control and coordination of movements based on environmental events. You will learn about the nervous system and hormones in animals as well as movements due to growth and responses due to stimulus in plants. The sub-topics in this chapter are listed below:
