Cell Practice Test

Which organelle is primarily responsible for the synthesis of the enzymes required for energy production? 

• Cell Wall

• Chloroplast

• Plasma Membrane

• Ribosome

The diagram shows the structure of a cell membrane.

Which molecules are the primary building blocks of the cell membrane?

• Carbohydrates

• Lipids

• Nucleic Acids

• Proteins

A student listed some characteristics about the nucleus of a living cell. Which characteristic did the student list incorrectly ?

• It contains DNA that codes for proteins

• It is smaller than any other organelle of the cell.

• It regulates the synthesis of new molecules in the cell.

• It is covered by a nuclear membrane

What is the relationship between the ribosomes and the plasma membrane in a cell?

• Ribosomes are embedded in the plasma membrane permeability

• Ribosomes are embedded in the plasma membrane, producing lipids for the membrane.

• Ribosomes produce cholesterol, which is a component of the plasma membrane.

• Ribosomes produce proteins, which are components of the plasma membrane.

Examine the cell diagram.

Which structure distinguishes plant cells from animal cells?

• W

• X

• Y

What is the role of mitochondria within the cell?

• Production of oxygen

• Production of carbohydrates

• Production of proteins

• Production of energy molecules

Observe the illustration.

What organelle is shown?

Vesicles are important membrane-bound organelles that serve many roles in the cell. Which sequence represents a correct pathway that vesicles would follow in helping to deliver a protein for export from the cell?

• Chloroplast --> Golgi body --> mitochondrion

• ribosome-->Golgi body-->cell membrane

• rough ER--> smooth ER--> Cell Wall

• Smooth ER -->

  mitochondrion--> vacuole
