Multiple Choice
Which structures are found in every living cell (including both prokaryotic and eukaryotic cells)?
A
Endoplasmic reticulum, Golgi apparatus, and lysosomes
B
Plasma membrane, cytoplasm, ribosomes, and genetic material (DNA)
C
Nucleus, mitochondria, and a plasma membrane
D
Cell wall, chloroplasts, and central vacuole
Verified step by step guidance1
Step 1: Understand the difference between prokaryotic and eukaryotic cells. Prokaryotic cells are simpler and lack membrane-bound organelles, while eukaryotic cells have complex structures including membrane-bound organelles.
Step 2: Identify structures common to all living cells. These include the plasma membrane, which encloses the cell; cytoplasm, the fluid inside the cell; ribosomes, which synthesize proteins; and genetic material (DNA), which carries the instructions for life.
Step 3: Recognize that organelles like the endoplasmic reticulum, Golgi apparatus, lysosomes, nucleus, mitochondria, chloroplasts, and central vacuole are membrane-bound and found only in eukaryotic cells, not in prokaryotes.
Step 4: Recall that cell walls are present in many prokaryotes and some eukaryotes (like plants), but not in all cells, so they are not universal to every living cell.
Step 5: Conclude that the structures found in every living cell, regardless of type, are the plasma membrane, cytoplasm, ribosomes, and genetic material (DNA).
