Important Points to Remember about Cell Biology:
- Cell biology define as it is the study of cell structure and function.
- George Emil Palade is considered the father of cell biology. He was the one who first used the electron microscope. With the help of an electron microscope, he discovered the ribosomes and the activity of the secretory proteins. He was also known for the study of cell fractionation
- Cell is discovered by Robert Hooke in 1665 in Bark of Plants. There are two types of Cell: Prokarytotic Cell and Eukaryotic Cell.
- All cells are made from the same major classes of organic molecules: nucleic acids, proteins, carbohydrates, and lipids.
- They provide structure and support, facilitate growth through mitosis, allow passive and active transport, produce energy, create metabolic reactions and aid in reproduction.
