Study Notes
Prokaryotic Cells
- Unicellular organisms that are generally smaller in size compared to eukaryotic cells.
- The cytoplasm within prokaryotic cells holds the genetic material, DNA, which is not enclosed in a nucleus.
- Lack of a true nucleus and membrane-bound organelles, distinguishing them from eukaryotic cells.
- Common examples include various forms of bacteria, showcasing the diversity within prokaryotic life.
Eukaryotic Cells
- Characterized by the presence of a nucleus that houses their DNA, distinguishing them from prokaryotes.
- Contain membrane-bound organelles, which perform specialized functions within the cell, enhancing efficiency.
- Generally larger in size than prokaryotic cells, allowing for more complex structures and functions.
- Include a variety of organisms such as animals, plants, and fungi, highlighting the complexity of life forms.
Shared Characteristics
- Both prokaryotic and eukaryotic cells contain DNA as genetic material, critical for inheritance and function.
- Both cell types possess a cell membrane that regulates entry and exit of substances, maintaining homeostasis.
- Cytoplasm is present in both, providing a medium for biochemical reactions essential for life.
