  • Although cells may differ widely in size, appearance, and function, their essential features are similar.

​

Important Points

• Almost all cells perform biochemical processes, generate and process energy, and store genetic information to be passed down to future generations of cells.
• Advanced single-celled and multicelled organisms have nuclei that carry the DNA, primitive cells; such as, bacteria, have no nucleus and carry their DNA loosely in coils throughout the cells
• The number of cells in an organism varies; for example, bacteria are single-celled organisms; the average adult human body has about one hundred trillion cells.
• Cells are the structural unit of all organisms and come in a range of sizes and shapes.
