Cell Structures and Functions Review Game

Complex organisms contain different levels of organization

that work together to maintain homeostasis. Which statements

correctly describe the roles of stem cells in maintaining a

complex organism? Select 2 that apply.

• Adult stem cells are totipotent cells that

  can differentiate into any cell type needed for repair.

• Stem cells are unspecialized cells that can become

  specialized during differentiation.

• An adult red blood stem cell can easily differentiate

  to become a nerve cell.

• Stem cell differentiation is the only process needed

  to maintain a complex organism.

• Adult stem cells can replenish themselves with

  identical copies formed during cell division.

What type of cell does not have a nucleus?

• eukaryotic 
• prokaryotic 

Plants and animal cells are examples of ___ cells 

• prokaryotic cells 
• eukaryotic cells 

What structures distinguish a plant cell from an animal cell?

• Plant cells have cell walls and ribosomes.
• Plant cells have cell walls and chloroplasts.
• Plant cells have chloroplasts and ribosomes.
• Plant cells have chloroplasts and mitochondria.

A cell has a cell wall but no nucleus or chloroplasts. What kind of cell is it?

• Prokaryotic

• Eukaryotic

• Plant

• Animal

Cells divide through the process of...

• Mitosis

• Differentiation

• Fertilization

• Mutations

Which statement describes the role of transcription factors in the process of stem cell differentiation shown in the diagram.

• Transcription factors are strands of DNA that can turn on (activate) or turn off (repress) certain genes in the stem cell.

• Transcription factors are proteins that can turn on (activate) or turn off (repress) certain genes in the stem cell.

• Transcription factors are regions of the cell membrane that allow signal molecules to enter the cell in order to turn off

  (repress) certain genes in the stem cell.

• Transcription factors are RNA molecules that can permanently turn off (repress) certain genes in the stem cell.

A model of stem cell differentiation is shown in the image. Examine the image. Describe the role of nucleic acids in the

differentiation model shown here. Select ALL descriptions that apply.

• Only certain genes are activated in stem cells to become differentiated.

• Additional DNA is inserted into a cell to create a specialized cell, such as the neuron shown here.

• Creating a differentiated cell requires that the majority of the genome within the stem cell to become activated.

• Deleting the genes that are not utilized in a cell conserves energy for the stem cells.

Which cell structure is found in all cells and controls what can come into or leave a cell?

• cell membrane
• cytoplasm
• nucleus
• vacuole

Cell organelles that are responsible for packaging and shipping proteins and other molecules made by the cell are called...

• Mitochondria
• Golgi Bodies

• Lysosomes
• Chlororplasts
