Understanding Common Cell Parts

The video tutorial explains that cells are too small to be seen with the naked eye, with over 100 trillion cells in the human body. It describes the cell membrane as a structure that holds the cell together and controls material movement. Inside the cell, the cytoplasm surrounds organelles, including the nucleus, which acts as the control center and contains DNA. DNA is crucial as it carries the genetic blueprint for cell development and function.
