This chapter highlights the fundamental unit of life- Cell. It explains that the existence of life depends upon cells, and this life can either be unicellular or multicellular. The main goal of this chapter is to explain cells as the structural and functional unit of life and compare the plant and animal cells to list out the differences between them. The chapter describes how life was created from a single cell. The chapter starts with the history of scientists involved in observing cells. Thus, students thoroughly understand how the study came into being.
The principal goal of this chapter is to observe the microscopic view and learn the unique features of the cell in terms of its shape, sizes, structural integrity and how to use these factors to differentiate between them easily. The chapter describes the cell organelle and the functions that they have in various biological processes. Thus, students get to discover more functions and understand the basic role of these organelles. The students learn about the characteristics of cells and explore more insights into the solid cell framework.
The important cell organelles include:
The chapter also investigates the features of the nucleus that performs an essential role in inheritance. Students get to know about the important avenues like protein production sites, Suicidal bags, storage of food, and the cell's powerhouse, leading to a much deeper knowledge of the concept. The chapter further examines how food is processed by these cells and converted into energy that we eventually utilise.
Students can establish a solid framework of genetic elements and evolution concepts. The chapter highlights the several functions performed by cells and elaborates the cell theory. Students also learn the unique features of the cell wall and plasma membrane regarding their permeability and rigidity.
