Selina Solutions for class 9 Biology Chapter 7 – Respiration In Plants
The chapter briefs about the respiration process that takes place in plants. All living cells take part in respiration, it is, therefore, necessary to understand the process of gaseous exchange that occurs within cells and hence the living entity ultimately.
Often, comparisons are drawn between burning and respiration process, this chapter lays out the differences. The different types of respiration such as aerobic and anaerobic respiration are also discussed along with their differences. Various experiments demonstrating the gaseous presence, the evolution of gases, different types of respiration etc are briefly covered in this chapter so that the reader gets a clear idea of all the important concepts.
