Who is credited with the concept of the cell as a biological building block?
Robert Hooke
Hooke’s work laid the foundation for cell biology.
What is the Cell Theory and who developed it?
The cell theory was developed by Schneider and Schwann
This theory states that all living organisms are composed of cells.
Who are Watson and Crick and what did they contribute to biology?
They are known for discovering the double helix structure of DNA
