What process includes a cell engulfing a particle and packages it inside a vesicle?
Phagocytosis Added: A more precise answer here is that this is a form of endocytosis. Phagocytosis usually is particle engulfing without the vesicle, necessarily.
The Intake of small membrane vesicles from the extracellular fluid is called?
exocytosis
Molecules bind to receptor sites and are enclosed in vesicles in the process of?
Endocytosis During endocytosis a small patch of plasma membrane folds in and encloses particles or tiny volumes of fluid at the cell surface.The membrane enclosure then pinches off into the cytoplasm,thereby forming a cytoplasmic vesicle
Phagocytosis vs pinocytosis?
Pinocytosis is the introduction of fluids into a cell by invagination of the cell membrane, followed by formation of vesicles within the cells. Phagocytosis is the engulfing and ingestion of bacteria or other foreign bodies by phagocytes.
How does the structure of the cell membrane facilitate endocytosis and exocytosis?
Endocytosis is the process of the cell membrane engulfing a small amount of matter from the extracellular fluid. Therefore the structure of the cell membrane folds inward, and traps and encloses the matter so it is inside the cell. Exocytosis is just the reverse of endocytosis. It takes the amount of matter thats inside the cell and ejects it out. The structure of the cell membrane gets fused from a vesicle (thus restoring membrane removed in endocytosis). The contents of the outward-bound vesicle are secreted into the extracellular fluid.

What organelle in the cell produces vesicles?
A vesicle is a fluid-filled cavity or an air-filled sac. The processes of budding and endocytosis produce vesicles. These processes involve the folding of the cell membrane over itself to make a pouch.

how does materials enter and exit a cell 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.

What is vesicular transport out of the cell?
Vesicular transport is an active process in which materials move into or out of the cell enclosed as vesicles. Vesicles are bubble-like structures surrounded by a membrane. They can form at the cell membrane or can fuse with the membrane. Solid particles, droplets of fluid or many molecules at a time can be moved across the membrane in vesicles. Vesicular transport is also known as bulk transport because large quantities of materials can be transported in this way. Th ere are two basic types of vesicular transport-endocytosis and exocytosis.
The formation of a vesicle?
In cell biology, a vesicle is a small organelle within a cell, consisting of fluid enclosed by a lipid bilayer membrane. Vesicles can form naturally, for example, during the processes of secretion (exocytosis), uptake (phagocytosisand endocytosis) and transport of materials within the cytoplasm. Alternatively, they may be prepared artificially, in which case they are called liposomes. If there is only one phospholipid bilayer, they are called unilamellar liposome vesicles; otherwise they are called multilamellar. The membrane enclosing the vesicle is also a lamellar phase, similar to that of the plasma membrane, and vesicles can fuse with the plasma membrane to release their contents outside of the cell. Vesicles can also fuse with otherorganelles within the cell.
How does a cell perform pinocytosis?
A cell performs pinocytosis when it needs a fluid that's outside of the cell. It does this by taking in the fluid particle in through the cell membrane. It wraps the particle in a layer of the membrane. See the related link for an example.
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.
