Oct 31, 2023 · Cells as Building Blocks. A cell is the smallest unit of a living thing. A living thing, whether made of one cell (like bacteria) or many cells (like a human), is called an organism. Thus, cells are the basic building blocks of all organisms. Several cells of one kind that interconnect with each other and perform a shared function form tissues ...
A cell is the basic unit of life as we know it. It is the smallest unit capable of independent reproduction. Robert Hooke suggested the name ‘cell’ in 1665, from the Latin cella meaning storeroom or chamber, after using a very early microscope to look at a piece of cork. It is also said that he thought that the rectangular chambers looked ...

Figure 3.2.1 3.2. 1: The cell is structurally and functionally complex. Although we defined the cell as the “most basic” unit of life, it is structurally and functionally complex (Figure 3.2.1 3.2. 1). A cell can be thought of as a mini-organism consisting of tiny organs called organelles. The organelles are structural and functional units ...
Oct 31, 2023 · All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these eight characteristics serve to define life. Figure 1.7.1 1.7. 1: Multicellular Organisms: A toad represents a ...

UNIT 3. UNIT3. Biology is the study of living organisms. The detailed description of their form and appearance only brought out their diversity. It is the cell theory that emphasised the unity underlying this diversity of forms, i.e., the cellular organisation of all life forms. A description of cell structure and cell growth by division is ...
