Quiz 1: Cell Theory and Cell Structures

What is the basis of scientists to determine whether an organism is a plant or an animal?

• how it obtains energy

• whether it is mobile or not

• how it reproduces 

• whether it is unicellular or multicellular

Which of the following organelles do plants and animals have in common?

•  nucleus, Golgi bodies, chloroplast and vacuoles

  
  

• mitochondrion, endoplasmic reticulum, and Golgi bodies

  
  

• mitochondrion, endoplasmic reticulum and chloroplast

  
  

• mitochondrion, chloroplast, endoplasmic reticulum and nucleus

  
  

What is the purpose of the mitochondria in both plants and animal cells?

•  provide proteins      

• package and transport proteins

•  store water, food and wastes  

•  act as the powerhouse of the cell and release energy

What is the function of the cytoplasm?

• releases energy in the cell

• holds all the organelles in place

• contains the pigment called chlorophyll

•  transports food, water and waste in and out of the cell

Which of the following best describes the function of the nucleus?

• control phospholipid production

•  transport materials around and out of the cell

• release energy in the cell 

• control the activities of the cell; acts the brain

Unlike eukaryotes, prokaryotes do not have _____________.

• Deoxyribonucleic acid

• Cell Wall

• Chloroplast/Plastids

• Membrane-bounded nucleus

What makes the smooth endoplasmic reticulum different from the rough

endoplasmic reticulum?

• The smooth endoplasmic reticulum is larger than the rough endoplasmic reticulum.

• The smooth endoplasmic reticulum is larger than the rough endoplasmic reticulum.

• The rough endoplasmic reticulum lacks the ribosomes attached to the smooth endoplasmic reticulum.

• The smooth endoplasmic reticulum lacks the ribosomes attached to the rough endoplasmic reticulum.

Why does cell division remain important to an adult organism even after it is fully developed? 

• It helps an adult to increase in size.

•  It helps adults to repair damaged cells and replace old cells.

• It helps adults to repair damaged cells and replace new cells.

• It helps in the division of red blood cells to ensure sufficient supply.

Which cellular organelle is responsible for the finalization and modification of proteins within the endomembrane system? 

• Nucleus

• Ribosomes

• Endoplasmic Reticulum

• Gogi Bodies

Arrange the following events that happens in the endomembrane system:

I. The mRNA is being transcribed in the ribosomes attached in the Rough ER to produce proteins. 

II. The Golgi Bodies finalizes and modifies the protein, and transport it out of the endomembrane system

III. The proteins are transported through vesicles from Rough ER to Golgi Bodies. 

IV. Nucleus contains the DNA that codes for mRNA. 

• III-IV-II-I

• IV-I-III-II

• II-I-III-IV

• IV-I-II-III
