Biology 8 - 3,4

A cell is placed in an isotonic solution. How does the cell maintain homeostasis in this environment?

• there is no movement of water molecules into or out of the cell because the concentrations of solute particles inside and outside of the cell are the same

• water will move across the membrane to the inside because the cell has a higher concentration of solute particles than the solution

• water will move across the membrane in both directions because the concentrations of solute particles inside and outside the cell are the same

• water will move across the membrane to the outside of the cell because the solution has a higher concentration of solute particles than the cell

The picture shows the process of _________ because solute particles are moving from an area of high concentration to low concentration.

Pay attention to the direction of the arrow. What type of cell transport is modeled?

• the model illustrates active transport because energy is required to move the solute particles from an area of low to high concentration

• the model illustrates diffusion because solute particles are moving from high to low concentration

• the model illustrates facilitated diffusion because protein channels allow solute particles to cross cell membrane

• the model illustrates osmosis because water molecules are moving from an area of high to low concentration

Which describes active transport, but not passive transport?

• moves particles across the cell membrane

• moves particles from high concentration to low concentration

• requires cellular energy

• particles diffuse directly through the lipid bilayer

Multicellular organisms contain organ systems. Which of the following BEST describes the organs in an organ system?

• the organs in an organ system are made up of similar cells

• the organs in an organ system are made up of similar tissues

• the organs in an organ system work together to perform a specific function

• the organs in an organ systems work together to perform all the functions a multicellular organism needs to maintain homeostasis
