Cell Biology Quiz

The Cell Theory states that all living organisms are composed of cells, that the cell is the basic unit of life, and that all cells come from pre-existing cells. This theory is significant in biology as it provides a fundamental understanding of the structure and function of living organisms, and forms the basis of modern biology.

The general characteristics of cells include being the basic structural and functional unit of all organisms, their microscopic size, and their ability to exist as independent units of life or form colonies or tissues in higher plants and animals.

Eukaryotic cells are larger, typically 10-100 µm in diameter, and have a defined nucleus and membrane-bound organelles. Prokaryotic cells are smaller, typically 1-10 µm in diameter, and lack a defined nucleus and membrane-bound organelles.

Understanding the correlation between cell structure and cellular function is crucial as it provides insights into how cells perform their specific roles in living organisms. It helps in understanding various physiological processes and developing treatments for cellular dysfunction.

Robert Hooke was the first person to observe cells in 1665. His observations of cork cells laid the foundation for the study of cells and the development of the Cell Theory.
