Which four structures are common to both eukaryotic and prokaryotic cells?

• A. Nucleus, mitochondria, cell wall, and chloroplasts
• B. Flagella, cilia, nucleolus, and vacuoles
• C. Cell membrane, ribosomes, cytoplasm, and DNA
• D. Endoplasmic reticulum, Golgi apparatus, lysosomes, and peroxisomes

Answer: (C)

Verified step by step guidance

1. Identify the basic structures that are essential for all cells, regardless of being eukaryotic or prokaryotic.
2. Understand that both eukaryotic and prokaryotic cells need a boundary to separate their internal environment from the external environment, which is the cell membrane.
3. Recognize that both types of cells require a mechanism to synthesize proteins, which is facilitated by ribosomes.
4. Acknowledge that both eukaryotic and prokaryotic cells contain cytoplasm, a jelly-like substance that fills the cell and holds organelles in place.
5. Realize that both cell types contain genetic material in the form of DNA, which is crucial for storing and transmitting genetic information.
