What is expcytosis?
Exocytosis refers to the process by which the contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane with the cell membrane. It can also be defined as the transport of material out of a cell by means of a sac or vesicle that first engulfs the material and then is extruded through an opening in the cell membrane
What is an active transport?
The methods of active transport are endocytosis, phagocytosis, pinocytosis, and exocytosis. Phagocytosis is the ingestion of a smaller cell or cell fragment, a microorganism, or foreign particles by means of the local in folding of a cell's membrane and the protrusion of its cytoplasm around the fold until the material has been surrounded and engulfed by closure of the membrane and formation of a vacuole. Endocytosis is the transport of solid mater of liquid into a cell by means of a coated vacuole or vesicle. Pinocytosis is the transport of fluid into a cell by means of local in foldings by the cell membrane so that a tiny vesicle or sac forms around each droplet, which is then taken into the interior of the cytoplasm. Exocytosis is the transport of material out of a cell by means of a sac or vesicle that first engulfs the material and then is extruded through an opening in the cell membrane.
What molecules move with endocytosis and exocytosis as opposed to diffusion or active transport?
The difference is that Active transport engulfs the substance by using the cells membrane. Exocytosis engulfs the substance by engulfing it into a vesicle, then bring it into the cell, and Exocytosis releases he substance from a cell by fusion of a vesicle. :)
When a vesicle fuses with the cell membrane to get rid of a particle what happens?
a vesicle does not fuse with the cell membrane. The cell membrane goes through endo- or exocytosis to absorb or eject a substance. In this case, exocytosis occurs, so the cell membrane engulfs the particle, pumps it through the membrane with the help of transport proteins, and then the vesicle breaks off and is gone.
Name the 2 ways that materials can pass through the cell membrane?
The two ways that materials can pass through the cell membrane are active transport and passive transport. In active transport the molecules cannot pass freely across the membrane and have to be carried across in ways that require energy. In passive transport the molecules can pass freely across the membrane in ways that do not take any energy.

How does the cell engulf liquid of small particles of matter?
Phagocytosis (cell eating) - form of endocytosis(folding in of cell membrane to trap material from the outside) ; cell membrane engulfs solid particles by wrapping around itPinocytosis (cell drinking) - form of endocytosis; cell engulfs liquids by sucking it in
Two ways that the cells move things by active transport?
Endocytosis and exocytosis. Endocytosis is when the material goes in the cell by engulfing it in. There are different types of endocytosis: phagocytosis, pinocytosis, and receptor meditated. Phagocytosis is when the cell engulfs the material in the vesicle. Pinocytosis is when there is fluid in the vesicle. Receptor meditated is when there are receptors in the vesicle to attract material. Excocytosis is when the material goes out of the cell by fusing with the membrane. Both of these active transport uses a vesicle that forms in order to bring the materials in or out of the cell.
When the cell membrane engulfs fluid droplets it is called?
Pinocytosis

a vesicle does not fuse with the cell membrane. The cell membrane goes through endo- or exocytosis to absorb or eject a substance. In this case, exocytosis occurs, so the cell membrane engulfs the particle, pumps it through the membrane with the help of transport proteins, and then the vesicle breaks off and is gone.
What is the Process by witch a membrane engulfs tiny droplets of liquid from surrounding?
Endocytosis
What are the differences between pinocytosis and phagocytosis?
Phagocytosis involves the cell taking in solid particles, while pinocytosis involves taking in fluids. In both, the cell engulfs the material with its membrane, creating vesicles.
The Na-K pump is an example of active transport?
Bulk Transport is an example of active transport. The process by which amoeba engulfs its food and secretes is a type of active transport. Amoeba forms false feet like pseudopodia and engulf food.Active and Passive transport both are related with plasma membrane. Active Transport is the transport of food across plasma membrane with expenditure of energy.
Is when extensions of the plasma membrane surround a macro-molecule?
Phagocytosis. Phagocytosis is when the plasma membrane surrounds a particle, engulfs it, and transports it inside a cell.
What is The movement of materials around inside a cell called?
1. Passive transport processes describe substances moving from regions of higher to lower concentrations without the use of energy. This includes diffusion, which is the basic movement of substances from an area of higher to lower concentration, as well as osmosis, which is the movement of water from an area of higher to lower concentration. Facilitated diffusioninvolves the diffusion of solutes or water through channel proteins in the plasma membrane.2. Active transport processes involve the movement of solute against a gradient, meaning it moves from areas of lower to higher concentration, and requires energy in the form of ATP. Transport proteins assist in moving these substances in and out of the membrane.3. Vesicular transport involves processes that use vesicles or other bodies in the cytoplasm to move large molecules or particles across the membrane. Endocytosis involves the capture of a substance outside of the cell when the membrane engulfs it. Two of these processes are called phagocytosis, in which the membrane engulfs solid material, and pinocytosis, which involves the membrane folding inward to form a channel for liquids to enter.
