The first cells were observed and named by. Aug 9, 2011 cells — sometimes even trillions of them (Figure 4). The body of some organisms like bacteria, protozoans and some algae is made up of a single cell while the body of fungi, plants and Both living and non-living things are composed of molecules made from chemical elements such as. Chapter 8 : Cell - The Unit Of Life. ▫ When atoms of the same kind get together they form elements. 5) Enzymes: The Catalysts of Life. The organization of these molecules into cells is one feature that distinguishes living things from all other matter. POINTS TO REMEMBER. CELL – STRUCTURE AND FUNCTION. Antoni van Leeuwenhoek (1632-1723) was probably thefiTSt human to ever observe a living cell. 9) Transport Across Membranes. Aug 14, 2014 Chapter 4 - Cell Structure and Function. ▫ The smallest unit of matter is called an atom. A eukaryotic cell (left) has membrane-enclosed DNA, which forms a structure called the nucleus (located at center of the eukaryotic cell; note the purple DNA enclosed in the pink nucleus). All organisms are composed of structural and functional units of life called 'cells'. A cell is chemical system that is able to maintain its structure and reproduce. Gram positive bacteria : Bacteria that take up gram stain. Cell Theory. 4) Nucleic Acids (III). Cells are the fundamental unit of life. Introduction. Mar 20, 2017 The cell theory states that all living organisms are made of one or more cells, cells are the basic units of structure and function, and cells come only from pre- existing cells.
