Unit 1 Biomolecule and Cell Review

Which of the following are differences between eukaryotic cells and prokaryotic cells? Select TWO correct answers.

• Eukaryotic cells have cell membranes.

• Eukaryotic cells are much larger.

• Eukaryotic cells have nuclei.

• Eukaryotic cells have ribosomes.

• Eukaryotic cells can be seen under a microscope.

What are two similarities between eukaryotic cells and prokaryotic cells? Select TWO correct answers.

• Both cells have mitochondria.

• Both cells have ribosomes.

• Both cells have nuclei.

• Both cells have cell membranes.

• Both cells are very complex.

Which type of cells have a cell membrane?

• Only eukaryotes have a cell membrane.

• Only prokaryotes have a cell membrane.

• Both eukaryotes and prokaryotes have a cell membrane.

• Neither eukaryotes or prokaryotes have a cell membrane.

Which of the following explains the statement “membranes organize cellular complexity”?

• Cytoplasm is held within a cell by the cellular membrane.

• Membranes allow specific functions to be most efficiently carried out inside the cell.

• Free-floating DNA within a cell is able to replicate.

• Membranes provide protection from extracellular invaders.

Why is the presence of DNA inside a cell not a reliable way to determine if a cell is prokaryotic or eukaryotic?

• Only prokaryotic cells have DNA.

• Both prokaryotic and eukaryotic cells have DNA.

• Only eukaryotic cells have DNA.

• DNA is only found in the nucleus.

Passive transport is the movement of molecules across the cell membrane without requiring an input of cellular energy. Identify which of these options are examples of passive transport.

Select TWO correct answers.

• The movement of water across the cellular membrane against the concentration gradient.

• The movement of molecules from areas of high to low concentration.

• The sodium-potassium pump which uses ATP for energy.

• The facilitated diffusion of oxygen across the cellular membrane.

• The movement of solutes across the cellular membrane from low to high concentration.
