 CH4- Cell Structure 
4.1 
 A cell is the smallest unit of a living thing. 
 Several cells of one kind that interconnect with each other and perform a shared 
function form tissues These tissues combine to form an organ (your stomach, 
heart, or brain), and several organs comprise an organ system (such as the 
digestive system, circulatory system, or nervous system). Several systems that 
function together form an organism (like a human being). Here, we will examine
