STAAR Test QUIZ 4a.4b

• the cell membrane is an impermeable membrane that prevents what from entering the cell

• the cell membrane allows solutes to enter the cell, which cause the cell to shrink

• the cell membrane allows water to enter and leave the cell

• the cell membrane removes solutes from the environment

• the organization of genetic material

• the location of the cytoplasm

• the role of the cell membrane

• the function of the flagella

Students created note cards comparing characteristics of eukaryotic and prokaryotic cells. Which set of note cards accurately compares these cells.

• 
• 
• 
• 

• cell W

• cell X

• cell Y

• cell Z

Which statement best describes the process of osmosis in an animal cell?

• sugar molecules move across the plasma membrane until the cell has enough energy to grow in size and divide

• water molecules move across the plasma membrane until the solute concentrations are equal on both sides of the membrane

• ions move across the plasma membrane until the inside of the cell has a high concentration of positive charges.

• Enzymes move across the plasma membrane until the cell has metabolized.

which table correctly identifies how the plasma membrane contributes to the maintenance of cellular homeostasis.

• 
• 
• 
• 

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

• Facilitated diffusion, becaue 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 concentratiogradient.

• DNA

• RNA

• C6H12O6

• ATP

• delivering packaged materials to the golgi apparatus for protein synthesis.

• Exchanging genetic information between the golgi apparatuses of separate cells.

• extracting portions of the golfi apparatus to be regenerated for growth within the cell.

• Transporting packaged molecules from the Golgi Apparatus to be released out of the cell.

• Energy conversions and synthesis of new molecules

• synthesis of new molecules and homeostasis

• transport molecules and energy conversions

• homeostasis and transport of molecules
