Question

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

Explanation:

• Cell wall: Prokaryotic cells (like bacteria) have a cell wall (e.g., peptidoglycan in many bacteria). Plant cells have a cell wall made of cellulose. Animal cells lack a cell wall.
• Mitochondria: Mitochondria are the power - houses of the cell. Prokaryotic cells do not have membrane - bound organelles (so no mitochondria). Plant and animal cells (eukaryotic cells) have mitochondria.
• Rough endoplasmic reticulum (RER): RER is involved in protein synthesis. Prokaryotic cells lack membrane - bound organelles (so no RER). Plant and animal cells (eukaryotic cells) have RER.

Answer:

	Prokaryotic cells	Plant cells	Animal cells
Mitochondria	Absent	Present	Present
Rough endoplasmic reticulum	Absent	Present	Present
