Cell Structure & Function: Sec. 1: The Discovery of Cells
Nitty Gritty Science・2 minutes read
Robert Hooke discovered cells in cork slices, leading to the cell theory supported by other scientists, including the idea that all living organisms are made up of cells. Advancements in microscopy, like electron microscopes, have allowed scientists to observe cell structures in detail, categorizing them into prokaryotes and eukaryotes with unique functions and benefits.
Insights
- Robert Hooke discovered cells in cork using a microscope, leading to the cell theory developed by Virchow, Schleiden, and Schwann, which states that all living organisms are made of cells, cells are the basic units of structure and function, and cells arise from pre-existing cells.
- Electron microscopes like SEMs and TEMs have enabled detailed observation of cell organelles, distinguishing prokaryotic cells (lacking membrane-bound organelles) from eukaryotic cells (containing membrane-bound organelles) found in diverse organisms, allowing for intricate chemical reactions within different parts of eukaryotic cells.
