Study Notes
Single-Celled Organisms
- Organisms composed of a single cell are known as unicellular organisms.
- Examples include bacteria, yeast, and some protozoa.
Fundamental Unit of Life
- The fundamental structural and functional unit of all living organisms is the cell.
- Cells carry out essential life processes, including metabolism, growth, and reproduction.
Plant Cell Structure
- The outer boundary of a typical plant cell is the cell wall.
- The cell wall provides structural support and protection, made primarily of cellulose.
Genetic Material in Cells
- Genetic material in a cell is contained within structures called chromosomes.
- Chromosomes are located in the nucleus in eukaryotic cells and are a vital part of heredity and cellular function.
Visualization of Cell Components
- Advanced microscopy techniques, such as electron microscopy, revealed the complete and clear view of all the components of a cell.
- These techniques allow for detailed imaging of cell structure, including organelles and other cellular components.
