Study Notes
Cell Theory and Cell Structure
- The main function of a cell, according to the Cell Theory, is to perform all the necessary functions for life, such as reproduction, metabolism, response to stimuli, growth, and evolution.
Cell Evolution
- Prokaryotic cells are considered the first cell type on earth, being simpler and more primitive than eukaryotic cells.
Cell Structure
- The main difference between prokaryotic and eukaryotic cells is the presence of a true nucleus and membrane-bound organelles in eukaryotic cells, whereas prokaryotic cells lack a true nucleus and membrane-bound organelles.
Cell Membrane
- The function of the cell membrane, also known as the plasma membrane, is to regulate what enters and leaves the cell, maintaining cellular homeostasis and protecting the cell from its environment.
- Small, non-polar molecules such as oxygen, carbon dioxide, and fatty acids can move freely across the plasma membrane.
