Study Notes
Cell Wall Discovery and Characteristics
- The cell wall was discovered by Hans Christian Gram, who also developed the Gram stain technique.
- Cell walls are generally found in plant cells, fungi, bacteria, and some protists.
- The cell wall is absent in animal cells and certain prokaryotic organisms, such as mycoplasmas.
Discovery of Cells
- The cell was discovered by Robert Hooke in 1665 when he examined cork under a microscope.
- Robert Hooke's discovery led to the identification of "cells," a term derived from the Latin word "cellula," meaning small room.
Association with Cell Wall
- Fungi are well-known for their cell walls, primarily composed of chitin.
- The presence of a cell wall is a characteristic feature in many living organisms except for animals.
Cell Theory Contributions
- Theodor Schwann and Matthias Schleiden are associated with the development of cell theory, which states that all living organisms are composed of cells, and cells are the basic unit of life.
Notable Discoveries
- Robert Hooke discovered the structure of plant cells and provided the foundation for microscopy and cellular biology through his detailed observations.
