Webthe cell. These substances pass into or out of the cell by diffusion, using passive transport. Substances moving into the cell are needed by the cell, and substances moving out of the cell are not needed by the cell. Study the diagram below. Draw arrows in the diagram to show whether each substance will move into or out of the cell. WebSelect all that apply.A) The cells are in different sizes and shapes.B) The nucleoli are larger than normal.C) The cells are contact inhibited.D) The cells do not resemble the tissue of origin.E) The cells are attached to an extracellular matrix.Ans: A, B, DFeedback:Undifferentiated cancer cells are marked by a number ofmorphologic changes.

Substances moving into the cell are needed by the cell, and substances moving out of the … WebIn facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. A concentration gradient exists for these molecules, so they have the potential to diffuse into (or out of) the cell by moving … Here, the cell can't import glucose for free using diffusion, because the natural ten…
WebIn comparing the relationship of the cell contents to those of the surroundings, three terms are used: 1.) isotonic: The two solutions have the same concentration of solutes, hence the same amount of water moves into the cell as moves out; 2.) hypotonic: The water outside the cell has less solute (hypo = less), and therefore more free water ... WebMaterials move within the cell’s cytosol by diffusion, and certain materials move through the plasma membrane by diffusion. Figure 1. Diffusion through a permeable membrane moves a substance from an area of high concentration (extracellular fluid, in this case) down its concentration gradient (into the cytoplasm).
