Eukaryotes and Prokaryotes

Which of the following indicates whether a cell is prokaryotic or eukaryotic?

• the presence or absence of ribosomes

• the presence or absence of a membrane-bound nucleus

• the presence or absence of a rigid cell wall

• the presence or absence of a cell membrane

Cells with a true nucleus and DNA enclosed in the nuclear membrane are eukaryotic cells. Animals, plants, fungi, and protists are examples of which type of cells?

• true nucleus

• eukaryotic

• prokaryotic

• prokaryotes

Cells that lack a membrane-bound nucleus are called what type of cells? Examples of these cells are bacteria.

• true nucleus

• eukaryotic

• prokaryotes

• prokaryotic

The length of most prokaryotic cells is about 1 to 10 μm whereas that of eukaryotic cells ranges from 10 to 100 μm. Which type of cells are larger in size?

• eukaryotic cells

• cell membrane

• cytoplasm

• ribosomes

Which organelle is responsible for protein synthesis in a cell?

• ribosomes

• mitochondria

• lysosomes

Which of the following is a double-membrane-bound organelle responsible for energy production in eukaryotic cells?

• chloroplast

• ER

• nucleus

• mitochondrion

The cell wall of eukaryotic cells is made up of cellulose. What is the composition of the cell wall in prokaryotic cells?

• capsule

• flagellum

• made up of cellulose

• Not made up of cellulose

Which structure is present in prokaryotic cells for extra protection?

• ribosomes

• capsule

• flagellum

• cell wall

What is the main difference in the structure of eukaryotic and prokaryotic cells?
