• Science has enormous influence on our lives. It provides the basis of much of modern technology---- the tools, materials, technique, and sources of power that make our lives and work easier. The term applied Science is sometimes used to refer to scientific research that concentrates on the development of technology. • Cells are the basic units of structure and function in living things. For example, just as bricks are the building blocks of a house or school, cells are the building blocks of life. Since you are alive, you are made of cells, too. Look closely at the skin on your arm. No matter how hard you look with your eyes alone, you won’t be able to see individual skin cells. • Since an animal cell does not have a cell wall, the cell membrane forms a barrier between the cytoplasm and the environment outside the cell. • Most of the cell’s energy is produced within these rodshaped organelles. • The cytoplasm is the area between the cell membrane and the nucleus. It contains a gel-like fluid in which many different or organelles are found. • The Golgi bodies receive materials from the endoplasmic retiiculum and send them to other parts of the cell. They also release materials outside the cell. • Some animals cells have vacuoles that store food, water, wastes, and other materials. • These small structures function as factories to produce proteins. • As you sail farther into the cytoplasm, you find yourself in a maze of passageways called the endoplasmic reticulum. These passgeways carry proteins and other materials from one part of the cell to another. • Almost all animal cells contain a nucleus.The nucleus directs all of the activities, including reprouction. • These small organelles found in many animal cells contain chemicals that break down food particles and worn - out cell parts. • 1.
