Detailed explanation-1: -Because most cells are too small to be seen by the naked eye, the study of cells has depended heavily on the use of microscopes.
Detailed explanation-2: -A microscope is an instrument that is used to magnify small objects. Some microscopes can even be used to observe an object at the cellular level, allowing scientists to see the shape of a cell, its nucleus, mitochondria, and other organelles.
Detailed explanation-3: -Microscopes are the tools that allow us to look more closely at objects, seeing beyond what is visible with the naked eye. Without them, we would have no idea about the existence of cells or how plants breathe or how rocks change over time.
Detailed explanation-4: -Cells are so small because they are easier to replace, and a cell needs to be small to be able to perform the tasks a cell needs to do. If cells were bigger it would be harder for the body to replace the cell without disrupting what is going on in the body and delaying a process.
Detailed explanation-5: -Cells are so little, so they can maximize their ratio of surface area to volume. Smaller cells have a higher ratio which allow more molecules and ions move across the cell membrane per unit of cytoplasmic volume. Cells are so small because they need to be able to get the nutrients in and the waste out quickly.
