Cell Structure, Genetics, Taxonomy, System Interactions

A prokaryotic and eukaryotic cell are shown. Which characteristic best distinguishes these cells as either prokaryotic or eukaryotic.

• the organization of the genetic material

• the location of the cytoplasm

• the role of the cell membrane

• the function of flagella

Students use a microscope to look for structures present in four different cells. The students placed an X for each structure that was viewed for each cell on the table shown. Which cell that was viewed is most likely a prokaryote?

• Cell W

• Cell X

• Cell Y

• Cell Z

Which type of movement across a cell's plasma membrane requires energy supplied by ATP?

• Passive transport

• simple diffusion

• Active transport

• osmosis

A type of cellular transport is shown:

• active transport because energy is being used to move molecules against the concentration gradient

• facilitated diffusion because energy is being used to move molecules with the concentration gradient.

• osmosis because energy is not being used to move molecules with the concentration gradient.

• endocytosis because energy is not being used to move molecules against the concentration gradient

Which model accurately shows a cell progressing through mitosis?

• 
• 
• 
• 

Which table best compares the events that occur during different stages of the cell cycle?

• 
• 
• 
• 

The diagram shows the major stages of the cell cycle and the percentage of time spent in each phase. Which statment best describes why a cell spends the majority of its time in interphase?

• The cell is growing and carrying out processes such as metabolism and DNA replication

• The cell is aging and processes are stopping as lysosomes clear dead cell matter away

• the cell needs time to synthesize spindle fibers to complete mitosis

• the cell needs time to complete cytokinesis

The activities in the cell cycle occur during specific phases. In which phases of the cell cycle is DNA replicated?

• Mitosis

• G1 Phase

• G2 phase

• S phase

A model of transcription and a codon chart a shown. Which amino acid would be coded first from the DNA strand being transcribed?

• Cys

• Phe

• Ile

• Met

a model of a biological process is shown. What is the purpose of this process?

• to replicate the DNA of an organism before cell division

• to assemble nucleotides in an mRNA chain along a DNA Template

• to synthesize amino acids used to unzip strands of DNA and copy the genetic code

• to translate the genetic code into a specific sequence of amino acids
