Study Notes
Cell Types and Structures
- Eukaryotic cells possess a nucleus, a unique structure that distinguishes them from prokaryotic cells.
- Prokaryotic cells lack a nucleus and are generally simpler in structure compared to eukaryotic cells.
Mitochondrial DNA
- Mitochondrial DNA (mtDNA) can be traced through generations, indicating its inheritance pattern and use in genetic studies.
Identification of Cells
- The first identification of cells was made using cork bark, showcasing early advancements in microscopy.
Basic Unit of Life
- The cell is the fundamental unit of structure and function in all living organisms, serving as the building block of life.
Cell Structures Common to Both Cell Types
- Cytoplasm serves to protect the internal structures of both eukaryotic and prokaryotic cells, providing a medium for biochemical reactions.
Endosymbiotic Theory
- The Endosymbiotic theory explains the evolution of eukaryotic cells, suggesting that they originated from symbiotic associations with prokaryotes, such as when a cell incorporates a cyanobacterium.
Genetic Information and Nucleus
- Removing the nucleus from a eukaryotic cell will not result in the creation of a prokaryotic cell because the nucleus contains essential genetic information required for cell function.
Classification of Cells
- Cells containing ribosomes in mitochondria are classified as eukaryotic due to the presence of mitochondria, an organelle associated with energy production.
Vulnerabilities in Cells
- Both prokaryotic and eukaryotic cells share critical components that can be harmed by certain chemicals, including DNA, cell membrane, cytoplasm, and ribosomes, indicating common vulnerabilities across cell types.
