NY Regents Transport (circulation)

The process of transport involves the​ (a)   of materials throughout an organism.

​ (b)   is the process where the products or digestion enter into the cells.

The plasma membrane (​ (c)   ) selectively regulates the ​ (d)   of materials, which helps in maintaining homeostasis (​ (e)   ).

Many small particles, such as ​ (a)   , diffuse through the membrane.

Most larger molecules such as ​ (b)   , cannot diffuse into or out of cells unless they are ​ (c)   digested.

• amino acids and monosaccharides
• proteins and starches
• chemically

What has to happen to the larger molecules such a as proteins and starches before they can pass (diffuse) through the cell membrane?

• Chemically digested

• Mechanically digested

• Built up through fusion

Match the following

• Diffusion

• form of passive transport, where molecules flow from high concentration to low

• Passive transport

• Diffusion of water

• Osmosis

• movement of materials through cell membrane without using energy

• Active transport

• movement of materials from a low concentration to high

  Uphill-using energy

The particles have characteristics that allow them to pass freely across the membrane. Select all of the statements that describe the particles or their movement based on the time-lapse diagram.

• The movement across the membrane requires energy from ATP.

• The movement across the membrane requires energy from glucose.

• The movement across the membrane does not require added energy.

• The particles crossing the membrane could be proteins or carbohydrates.

• The particles crossing the membrane could be water (H2O) or oxygen (O2).

The concentration of water is higher in the soil than in plant root cells. Water moves into root cells of a plant by...

• swell because water diffuses out of the cell
• shrivel because water diffuses out of the cell
