How does materials enter and exit a cell and How does the process work?
Actually there are three simple scientific terms which shows how the cell intake and throw out anything. A cell interacts with the outside world with the membrane only and that is the cellulose membrane as in plants of the plasma membrane as in animal. These process are mainly called as endocytosis ( intake ) and exocytosis ( exit ) of material in the cell through cell membrane. Endocytosis is the movement of materials into a cell via membranous vesicles. Exocytosis is the movement of materials out of a cell via membranous vesicles. Vesicles are nothing but a bag like structure formed of the broken cell membrane when it captures the chemical or any external thing for intake or when it capture something from inside of cell for exit. # Exocytosis ## Process where a cell secretes macromolecules by fusion of vesicles with the plasma membrane. ## Vesicle usually budded from the ER or Golgi and migrates to plasma membrane. ## Used by secretory cells to export products (e.g. insulin in pancreas, or neurotransmitter from neuron). # Endocytosis ## Process where a cell takes in macromolecules by forming vesicles derived from the plasma membrane. ## Vesicle forms from a localized region of plasma membrane that sinks inward; pinches off into the cytoplasm. ## Used by cells to incorporate extracellular substances. # There are three types of endocytosis: (1) phagocytosis, (2) pinocytosis and (3) receptor-mediated endocytosis. ## Phagocytosis ### (cell eating) Endocytosis of solid particles. ### Cell engulfs particle with pseudopodia and pinches off a food vacuole. ### Vacuole fuses with a lysosome containing hydrolytic enzymes that will digest the particle. ## Pinocytosis ### (cell drinking) Endocytosis of fluid droplets. ### Droplets of extracellular fluid are incorporated into small vesicles. ### The process is not discriminating. The cell takes in all solutes dissolved in the droplet. ## Receptor-Mediated Endocytosis ### Endocytosis when coated pits form vesicles when specific ligands bind to receptors on the cell's surface. ### More discriminating process than pinocytosis. ### Enables cells to acquire bulk quantities of specific substances, even if they are in low concentration in extracellular fluid (e.g. cholesterol). ### Membrane-embedded proteins with specific receptor sites exposed to the cell's exterior, cluster in regions called coated pits. ### A layer of clathrin, a fibrous protein, lines and reinforces the coated pit on the cytoplasmic side. ### A molecule that binds to a specific receptor site of another molecule is call a ligand.

How does a cell use exocytosis to release the contents of a vesicle outside the cell?
In exocytosis, materials are exported out of the cell via secretory vesicles. In this process, the Golgi complex packages macromolecules into transport vesicles that travel to and fuse with the plasma membrane. This fusion causes the vesicle to spill it's contents out of the cell.
What is a solute and solvent?
A solute is a solid, being dissolved in liquid. A solvent is the liquid in which the solid, or solute is being dissolved in.
Is a solvent the substance that dissolves the solute?
Yes because the solute gets dissolved when put in the solvent
What is the different between phagocytosis and pinocytosis?
Phagocytosis is the cellular intake of large molecules (e.g. proteins, polysaccharides) by pseudopodia; a large food vacuole is formed. Pinocytosis is the cellular intake of small molecules dissolved in the extracellular fluid; a smaller vesicle is formed. In both cases, matter is entering the cell.
What kind of endocytosis takes in small dissolved molecules or fluids?
Pinocytosis #SWAG
What is phygocytosis?
In cellular biology, pinocytosis ("cell-drinking", "bulk-phase pinocytosis", "non-specific, non-absorptive pinocytosis", "fluid endocytosis") is a form of endocytosis in which small particles are brought into the cell-forming an invagination, and then suspended within small vesicles that subsequently fuse with lysosomes to hydrolyze, or to break down, the particles. This process requires a lot of energy in the form of adenosine triphosphate, the chemical compound used as energy in the majority of cells. Pinocytosis is used primarily for the absorption of extracellular fluids (ECF), and, in contrast to phagocytosis, generates very small vesicles. Unlike receptor-mediated endocytosis, pinocytosis is nonspecific in the substances that it transports. The cell takes in surrounding fluids, including all solutes present. Pinocytosis also works as phagocytosis, the only difference being that phagocytosis is specific in the substances it transports. Phagocytosis actually engulfs whole particles, which are later broken down by enzymes, such as lysosomes, and absorbed into the cells. Pinocytosis, on the other hand, is when the cell engulfs already-dissolved or broken-down food.

Eukaryotic cells have bodies that wrap protein and lipid molecules in vesicles?
The phospholipid bilayer can reach out with its membrane, and engulf proteins and lipid incoming to the cell. This is known either as Pinocytosis or Phagocytosis- both are forms of endocytosis of the cell. Pinocytosis is the ingestion of dissolved materials by endocytosis where the cell membrane invaginates and pinches off small droplets of fluid in a pinocytotic vescile. In Phagocytosis, the cell membrane invaginates and pinches off, putting the proteins or lipids in a phagocyotic vacuole (endosome) and it fuses with lysosomes that digests the contents.

What are 2 ways a cell eats food?
Two ways a cell can eat food is by one, endocytosis which is when non-dissolved materials or food enter through the cell membrane to the cell's cytoplasm. These non-dissolved materials come from the outside environment. This way also includes phagocytosis in which an cell use pseudopods to help bring in the non-dissolved materials from the outside environment in to the cytoplasm. The second way is what a plant cell use get it's food is by chloroplast ( part of a cell ) which makes food from carbon dioxide, sunlight, and water.
Example for pinocytosis?
Pinocytosis is the engulfing of the extracellular fluid by cells. Or simple we could say that it is a "cell-drinking". -- Pinocytosis is a form of endocytosis in which small particles are brought into the cell suspended within small vesicles (pinocytotic vesicles) which subsequently fuse with lysosomes to hydrolyze, or to break down, the particles. This is important for the cell's absorption of extracellular fluids. Pinocytosis is a process that allows cells to take on hydration or other external substances.
What is the direction of net movement in endocytosis?
Endocytosis moves large and polar molecules, that are unable to pass through a cell's plasma membrane, from the outside of a cell to the inside of a cell. There are three types of endocytosis:Phagocytosis (cell eating)- the process by which a cell engulfs macromolecules.Pinocytosis (cell drinking)- the process by which small dissolved substances enter a cell. Small vesicles pinch off of the plasma membrane into the cell.Receptor-mediated endocytosis- the process by which a cell engulfs molecules specific to its receptor proteins. Molecules bind to specific receptor proteins in the receptor-coated pit. Basically, this type of endocytosis is the same as phagocytosis. The only difference is the molecule specificity, which is sensitive to the type of receptor proteins.See the following link for an animation of these cellular processes and exocytosis:http://bcs.whfreeman.com/thelifewire8e/content/cat_040/0504003.html
