which of the following are features all cells have in common?
chloroplasts
cell wall
cytoplasm
endoplasmic reticulum
plasma membrane

Explanation:

• Chloroplasts: Only present in plant cells (especially photosynthetic ones) and some protists, not in animal cells or many prokaryotes. So not common to all cells.
• Cell wall: Animal cells lack a cell wall (they have a plasma membrane), while plants, fungi, and prokaryotes have it. So not all cells have a cell wall.
• Cytoplasm: All cells (prokaryotic and eukaryotic) have cytoplasm, which is the gel - like substance within the cell where cellular processes occur.
• Endoplasmic reticulum: This is a membrane - bound organelle found only in eukaryotic cells. Prokaryotic cells do not have an endoplasmic reticulum.
• Plasma membrane: All cells (prokaryotic and eukaryotic) are surrounded by a plasma membrane (also called the cell membrane) which regulates the movement of substances in and out of the cell.

Answer:

C. Cytoplasm, E. Plasma membrane
