Question
complete the table to compare prokaryotic and eukaryotic cells. prokaryotic cells eukaryotic cells are generally larger are structurally less complex have more diverse ways to get energy and process nutrients lack membrane - bound organelles
Brief Explanations
- Size: Eukaryotic cells are generally larger than prokaryotic cells. Prokaryotic cells are typically \(0.1 - 5.0\) micrometers in size, while eukaryotic cells range from \(10 - 100\) micrometers.
- Structural Complexity: Prokaryotic cells are structurally less complex. They lack a nucleus and most membrane - bound organelles. Eukaryotic cells have a nucleus and various membrane - bound organelles (e.g., mitochondria, endoplasmic reticulum), which add to their complexity.
- Energy and Nutrient Processing Diversity: Prokaryotes have more diverse ways to get energy and process nutrients. For example, some prokaryotes are chemoautotrophs (use inorganic substances for energy and carbon), photoheterotrophs (use light for energy and organic compounds for carbon), etc. Eukaryotes mainly rely on more “standard” modes like photosynthesis (in plants - a type of photoautotrophy) and cellular respiration (heterotrophic eukaryotes).
- Membrane - Bound Organelles: Prokaryotic cells lack membrane - bound organelles. Eukaryotic cells have them.
