Part 5 Characteristics of Life
O.G.R.E. Organization Cells are the basic unit of all living things. Cells, like all living things, have an inside and an outside. The boundary separating the inside from the outside of an individual cell is called the cell membrane. Within the cells, another structure called the nucleus is also surrounded by a membrane. Some organisms have only one cell (single-celled organism) which may or may not have a nucleus. Growth Living things increase in size. Organisms made of one cell do not grow as large as organisms make of many cells. But all living things need to get energy. All living things also need to obtain materials to build new structures inside cells or replace worn-out cell parts. As a result, individual cells grow larger over time. Reproduction Living things reproduce, forming other organisms like themselves. Every organism contains genetic material. which is a code contained in a special molecule called DNA. In order to reproduce, an organism must make a copy of this material, which is passed on to its offspring. Some single-celled organisms reproduce by a process called binary fission. In binary fission, material from one cell separates into two cells. The genetic material of the original cell first doubles so that each daughter cell has an exact copy of the DNA of the original cell. One cell divides into two cells, two cells divides into 4 cells, etc. Response to Environment Organisms respond to changes in the environment. Even microscopic organisms respond to conditions such as light, temperature, and touch. The ability to respond allows organisms to find food, avoid being eaten or perform other tasks necessary to survive. Part 6 Living things need energy, materials, and living space. Application Chose an animal and describe how it is organized, grows, reproduces and responds to its environment. |
