a) Describe diffusion. b) What does selectively permeable mean? c) Does diffusion require energy from the cell? What is the diffusion of water through a selectively permeable membrane called? a. facilitated diffusion b. active transport c. osmosis d. phagocytosis e. endocytosis ...
Membranes are selectively permeable. What does this mean? If cell membranes WEREN'T selectively permeable to compounds like sugars and amino acids, what would happen to the nutrients that the cell brings in? Briefly describe five functions of membran...
What does it mean to say that a membrane is selectively permeable? Explain how the plasma membrane of the cell is selectively permeable. How are turgor pressure and osmosis related? What does a high epithelial cell count in a wet prep mean?
Turgor pressure isthe hydrostatic pressure in excess of ambient atmospheric pressurewhich can build up in living, walled cells. Turgor is generated through osmotically driven inflow of water into cells across a selectively permeable membrane; this membrane is typically the plasma membrane. What is Pulv...
What is a Semipermeable Membrane? Discussion Comments By scifreak — On Apr 20, 2011 Since cells are selectively permeable, does that mean they can be selective and allow prescribed medications into the blood stream? For example, I take high blood pressure medicine. Is the reason it works is...
How does diffusion of solute though the membrane affect osmosis? Why? What happens when you place an animal cell in a hypotonic solution? Hypertonic? Biological membranes are said to be selectively permeable (or semi-permeable). What does this term mean, and how does...
Osmosis is the process in which ___ diffuses across a cell membrane. a. water b. energy c. protein d. oxygen a) Describe diffusion. b) What does selectively permeable mean? c) Does diffusion require energy from the cell? How does osmosis oc...
What does it mean for the cell membrane to be semipermeable? How do human epithelial cells and plant cells differ? How do ciliated epithelial cells keep bronchioles clean? What does it mean to say that a membrane is selectively permeable? Explain how the plasma membrane of the cell is select...
How does a membrane create a semi-impermeable barrier separating the inside and outside of the cell? How does the structure of the cell membrane make it selectively permeable? What's the function of a permeate membrane in reverse osmosis? 1. What is the cell membrane? 2. What does it ...
What structure (found in all cells) surrounds the cell membrane and gives support to the cell? How does the structure of the cell membrane make it selectively permeable? Cells of which germ layer are not present in the oropharyngeal membrane? Explain your answer. What type of cell ha...
