Endocytosis
Lol you go to IHS?
Re: Lol, I'm just googling the questions for Mr. Elliott's homework, let's see. Bulk transport of substances out of the cell..
LOL im in IHS 2 im in Mr. elliotts class 2, did u guys graduate, and i wanna ask
lower concentration of solutes outside the cell than inside, what is its prefix
What else can I help you with?
How does a cell expel large particles?
EXOCYTOSIS-When a large particle must be removed from the cell, the cell uses a different process. In EXOCYTOSIS,vesicles are formed at the endoplasmic reticulum or Golgi complex and carry the particles to the cell membrane.ENDOCYTOSIS-In ENDOCYTOSIS, the cell membrane surrounds a particle and encloses it in a vesicle. This is how large particles, such as other cells, can be brought into a cell.They both require the use of ATP though, like active transport. However, passive transport doesn't require ATP.Phagocytosis is the cell that takes in large particles. This is used in biology.
What substance undergoes osmosis?
Water moves across the cell membrane through the process of osmosis.
A means of bringing fairly large particles into the cell?
Phagocytosis
When would you want to use selective media?
Selective Media - Our cell membrane has a selective permeable property. This type of membranes are important when we want to allow certain sized particles to enter while restricting other sized particles to enter our cell. Selective permeable membrane is of great use in biological samples.
What is the outer layer of a cell?
The outer layer of a cell is the cell membrane or plasma membrane
Which one moves faster across the cell membrane the large or the small?
Small particles move faster across the membrane.
What is phagocytosis and how does it work?
large particles or cells are engulfed by the cell plasma membrane
What organelle transports large particles out of the cell?
cell membrane
How a cell membrane moves large particles into a cell?
Through integral proteins (tube shaped proteins that have one opening in the extra cellular matrix and the other opening inside the cell).
Occurs when the plasma membrane surrounds a large substance inside the cell and moves it outside the cell?
exocytosis
What occurs when the plasma membrane surround large substance inside the cell and moves it outside the cell?
exocytosis
What book transport process moves materials into cells?
The process that moves materials into cells is called endocytosis. During endocytosis, the cell membrane surrounds particles or substances outside the cell, forming a vesicle. The vesicle then fuses with the cell membrane and releases its contents into the cell.
What happens if the particle is too large to get across the membrane?
The cell use something called a protein channel that helps larger particles across the cell membrane.
What are the functions for the cell membrane?
The cell membrane keeps out unwanted particles from the cell.
Which particles-starch or Lugol's-were able to cross the model cell membrane?
The Lugol's solution particles were able to cross the model cell membrane, while the starch particles were too large to pass through. Starch is a large molecule that cannot diffuse across the membrane, while Lugol's solution contains smaller molecules (iodine and iodide ions) that are able to pass through.
What happen to large molecules such as food particles during phagocytosis?
During Phagocytosis large particles are enveloped by the cell membrane of a (usually larger) cell and internalized to form a phagosome, or "food vacuole."
Type of active transport that moves large particles into a cell through vesicles?
Endocytosis - the way in which cells take in food and other materials. The cells membrane wraps around the particle it needs on its outside, ingesting it. This then becomes trapped within a vacuole inside the cells cytoplasm where it is broken down, digested, and absorbed by enzymes.
