Numbers of organelles are found in cell structure and each one play its role independently and this refers to as division of labor. Figure 4: Structure of animal and plant cell Descriptions of organelles and their function within cells. The Nucleus This is the largest organelle in a cell. A collection of cells that function together to perform the same activity is known as tissue. Masses of tissue work collectively to form an organ that performs specific functions in the body. Despite this structural organization, all activity boils down to the cell –a complex unit that makes life possible. Human Cell, Structure and Functions:File Size: 2MB. A cell is a membrane-covered structure that contains all of the materials necessary for life. Cells are the smallest unit of life, which means they are the smallest structures that can perform life functions. Information obtained from Science Fusion - The Diversity of Living Things - .
