Question

which structures are found in each cell type? complete the table.
mitochondria
cell wall
rough endoplasmic reticulum
prokaryotic cells
plant cells
animal cells

Explanation:

• Prokaryotic cells: Lack membrane - bound organelles like rough endoplasmic reticulum and mitochondria. Most have a cell wall (composition varies from plant cell walls).
• Plant cells: Have a cellulose cell wall for structure. Contain rough endoplasmic reticulum (involved in protein synthesis) and mitochondria (for energy production).
• Animal cells: Do not have a cell wall. Have rough endoplasmic reticulum (for protein synthesis and transport) and mitochondria (for ATP production).

Answer:

• Prokaryotic cells:
• Rough endoplasmic reticulum: No
• Cell wall: Yes (in most cases, e.g., bacteria have peptidoglycan cell walls)
• Mitochondria: No
• Plant cells:
• Rough endoplasmic reticulum: Yes
• Cell wall: Yes (cellulose - based)
• Mitochondria: Yes
• Animal cells:
• Rough endoplasmic reticulum: Yes
• Cell wall: No
• Mitochondria: Yes
