Cell Structure and Function Test

In eukaryotic cells, a number of organelles allow the cell to produce and distribute proteins and other important contents. Where are proteins/important contents modified, packaged, and further distributed?

• Golgi apparatus

• Ribosomes

• Rough endoplasmic reticulum

• Smooth endoplasmic reticulum

A model of an unknown cell is shown. A scientist was studying the unknown cell and found that it does not have a nucleus or membrane bound organelles. Which of the following best describes the unknown cell?

• It is a prokaryote because it does not have a nucleus or membrane bound organelles.

• It is a prokaryote because it does have a nucleus.

• It is a eukaryote because it does have a nucleus.

• It is a eukaryote because it does not have a nucleus or membrane bound organelles.

All cells contain cell membranes. Which of the following describes the composition and function of cell membranes?

• Cell membranes are composed of carbohydrates, which allow no materials to enter and leave the cell.

• Cell membranes are composed of cellulose, which provide rigidity for the cell.

• Cell membranes are composed of cytoplasm, which allows proteins to be excreted by the cell.

• Cell membranes are composed of phospholipids, which provide flexibility and semi-permeability.

The model shows a substance crossing a cell membrane. Which of the following best describes the process?

• The model shows the process of active transport because the solute particles are moving from an area of low concentration to an area of high concentration.

• The model shows the process of bulk transport because the solute particles are moving from an area of low concentration to an area of high concentration.

• The model shows the process of diffusion because solute particles are moving from an area of high concentration to an area of low concentration.

• The model shows the process of osmosis because the solute particles are moving from an area of high concentration to an area of low concentration.

Which organelle is responsible for shipping, sorting and packaging proteins in the cell?

The illustration shows a model of the transport of solute particles from outside the cell to inside the cell. What type of cell transport is modeled?

• The model illustrates active transport because energy is required to move the solute particles from an area of lower concentration to an area of higher concentration.

• The model illustrates diffusion because solute particles are moving from an area of higher concentration to an area of lower concentration.

• The model illustrates facilitated diffusion because protein channels allow solute particles to cross the cell membrane.

• The model illustrates osmosis because water molecules are moving from an area of higher concentration to an area of lower concentration.

You are comparing two cells. Cell 1 has a cell wall, cell membrane, and ribosomes, but no nucleus or mitochondria. Cell 2 has a nucleus, cell membrane, ribosomes, and mitochondria, but no cell wall. What conclusion about the cells does the data support?

• Cell 1 is from a plant; Cell 2 is from an animal.

• Cell 1 is prokaryotic; Cell 2 is from a plant.

• Cell 1 is prokaryotic; Cell 2 is from an animal.

• Cell 1 is eukaryotic; Cell 2 is prokaryotic.
