Study Notes
Cell Characteristics
- Prokaryotic and eukaryotic cells can both feature a cell wall and flagella.
- Prokaryotic cells do not have a membrane-bound nucleus.
- Bacterial cells serve as a prime example of prokaryotic cells.
- Eukaryotic cells include organisms such as plants and animals.
Eukaryotic Cells
- Characterized by the presence of a nucleus, which is responsible for controlling major cell activities.
- Generally larger and more complex compared to prokaryotic cells.
- Contain membrane-bound organelles that perform specific functions within the cell.
Prokaryotic Cells
- Contain circular DNA and lack a nucleus and membrane-bound organelles.
- Generally smaller and simpler in structure than eukaryotic cells.
Additional Cell Information
- The age of the cells is not a distinguishing factor between prokaryotic and eukaryotic cells.
- Cytoplasm encompasses everything inside a cell, excluding the nucleus.
- Vacuoles function to store essential materials required by the cell.
