Parts and Function of a Cell

Multiple Choice

Which of the following structures is found in eukaryotic but NOT in prokaryotic cells?

• DNA

• Plasma Membrane

• Mitochondria

• Ribosomes

Multiple Choice

In terms of cellular function, what is the most important difference between prokaryotic and eukaryotic cells?

• Eukaryotic cells lack many of the organelles found in prokaryotes.

• Eukaryotic cells are compartmentalized, which allows for specialization.

• Eukaryotic cells can synthesize proteins but prokaryotic cells cannot.

• Eukaryotic cells are larger than prokaryotic cells.

Multiple Choice

Bacterial cells are prokaryotic. Unlike a typical eukaryotic cell, they __________

• lack ribosomes

• have smaller nucleus

• lack a plasma membrane

• have no membrane-bounded organelles in their cytoplasm

Multiple Choice

Which of the following features do prokaryotes and eukaryotes have in common?

• ribosomes, plasma membrane, and cytoplasm

• ribosomes, nucleus, and plasma membrane

• nucleus, plasma membrane, and ribosomes

• mitochondria, ribosomes, and cytoplasm

Multiple Choice

Why is the plasma membrane described as a fluid-mosaic model?

• because it is a wax suspended within a mosaic of phospholipids.

• because it is a mosaic of proteins suspended within a phospholipid bilayer.

• because it is a polysaccharide mosaic suspended within a protein bilayer.

• because it is a mosaic of phospholipids suspended within a protein bilayer.

Multiple Choice

Which of these structures is involved in protein synthesis?

• Plasma Membrane

• Mitochondria

• Lysosome

• Ribosome

Multiple Choice

Which of the following categories best describes the function of the rough endoplasmic reticulum?

Multiple Choice

Which of the following is found in a plant cell, but not in an animal cell?

• Chloroplast

• Plasma Membrane

Multiple Choice

True or False: Plant cells have a more rigid structure than animal cells.

• True

• False

Multiple Choice

Why does a plant cell have a fixed shape and an animal cell does not?

• Plant cells have larger vacuoles than animal cells.

• The process of photosynthesis causes plant cells to have a rigid shape

• The cell membrane of a plant cell is surrounded by a cell wall.

Multiple Choice

Which of the following structures is found in animal cells but NOT in plant cells?

• Plasma Membrane

• Rough Endoplasmic Reticulum

Multiple Choice

Dye injected into a plant cell might be able to enter an adjacent cell through __________.

• Cell Wall

• Gap Junction

• Plasmodesmata

• Tight Junction

Multiple Choice

Your intestine is lined with individual cells. No fluids leak between these cells from the gut into your body. Why? 

• The intestinal cells are bound together by plasmodesmata.

• The intestinal cells are bound together by tight junctions.

• The intestinal cells are bound together by gap junctions.

• The intestinal cells are bound together by the extracellular matrix.

Multiple Choice

Which of the following statements correctly describes a common characteristic of a plant cell wall and an animal cell extracellular matrix?

• Both are permeable to water and small solutes.

• Both contain large amounts of collagen.

• Both are composed primarily of carbohydrates.

• Both are permeable to water and small solutes, and both contain large amounts of collagen.
