Lesson Worksheet: Eukaryotic Cell Structure Biology

In this worksheet, we will practice identifying the key organelles in a eukaryotic cell and describing their functions.

Q1:

Which of the following tables correctly differentiates between the structure and function of the rough and smooth endoplasmic reticulum?

  • A
    TypeStructureFunction
    SmoothFlat appearance, ribosomes on the surface Synthesize, store, and transport lipids
    RoughTubular appearance, no ribosomesProvide a surface area for the synthesis of proteins
  • B
    TypeStructureFunction
    SmoothTubular appearance, no ribosomesSynthesize, store, and transport lipids
    RoughFlat appearance, ribosomes on the surface Provide a surface area for the synthesis of proteins
  • C
    TypeStructureFunction
    SmoothTubular appearance, no ribosomesProvide a surface area for the synthesis of proteins
    RoughFlat appearance, ribosomes on the surface Synthesize, store, and transport lipids
  • D
    TypeStructureFunction
    RoughTubular appearance, no ribosomesSynthesize, store, and transport lipids
    SmoothFlat appearance, ribosomes on the surface Provide a surface area for the synthesis of proteins

Q2:

Which of the following is not a function of the Golgi apparatus?

  • AForming Golgi vesicles that can transport substances through the cell
  • BProviding the site for protein synthesis
  • CTransporting, modifying, and storing lipids
  • DProducing secretory enzymes
  • ECombining proteins with carbohydrates to form glycoproteins

Q3:

Which eukaryotic organelle has a membrane folded into extensions called cristae?

  • AEndoplasmic reticulum
  • BRibosome
  • CMitochondrion
  • DNucleus
  • EChloroplast

Q4:

What is the main function of mitochondria in a eukaryotic cell?

  • AMitochondria provide the site for the synthesis of proteins.
  • BMitochondria act as the control center of the cell, determining the cell’s activities.
  • CMitochondria contain the majority of the cell’s genetic material.
  • DMitochondria provide the site for the aerobic stages of respiration.
  • EMitochondria are where proteins are packaged and processed before being sent to the cell membrane.

Q5:

Which polysaccharide is the major component of plant cell walls?

  • AStarch
  • BCellulose
  • CGlucose
  • DGlycogen

Q6:

Which of the following best describes the structure of a ribosome?

  • ARibosomes have two subunits, both equally sized, that contain ribosomal RNA and proteins.
  • BRibosomes have two subunits, a large one and a small one, that contain ribosomal DNA and carbohydrates.
  • CRibosomes have two subunits, both equally sized, that contain ribosomal DNA only.
  • DRibosomes have two subunits, a large one and a small one, that contain ribosomal RNA and proteins.

Q7:

What feature or requirement of a cell will determine how many mitochondria a cell will contain?

  • AThe number of nutrients the cell requires
  • BThe number of proteins the cell needs to synthesize
  • CThe amount of energy the cell requires
  • DThe number of times the cell needs to differentiate

Q8:

The micrograph shows a cell viewed with a transmission electron microscope. A circular nucleus is visible, with a nucleolus in the center.

Which of the following is not a function of a nucleus in a eukaryotic cell?

Circular nucleus
  • AManufacturing ribosomal RNA and forming ribosomes
  • BStoring genetic material as DNA that coils into chromosomes
  • CActing as the site of translation to form polypeptides from mRNA
  • DActing as the site of transcription to form mRNA strands from DNA

Q9:

The micrograph shows a cell viewed under a transmission electron microscope. A circular nucleus is visible.

Which of the following is not part of the structure of a nucleus?

Circular nucleus
  • ANuclear envelope
  • BNucleolus
  • CNucleoplasm
  • DNuclear pores
  • ENuclear cristae

Q10:

What is the primary function of the cytoskeleton in a eukaryotic cell?

  • ATo initiate transcription and translation of the cell’s genetic information
  • BTo control the positioning and movement of organelles within the cell
  • CTo synthesize proteins for the cell
  • DTo actively control what substances enter and leave the cell
