All eukaryotic cells have membrane-covered compartments called that form when part of the cell membrane an object and pinches off?
It is vesicles.
What are the membrane-bound sacs the Golgi complex pack protein and other materials into?
These membrane bound sacs are called vesicles.
What are the membrane-bound sacs the Golgi complex packs proteins and other material into?
These membrane bound sacs are called vesicles.
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.
What is the vesicular formation membrane bound sac called?
These are called vesicles and they transport various substance into the cell and out of the cell.
All eukaryotic cells have membrane-covere compartments called?
The membrane-covered compartment of eukaryotic cells are called vesicles. The vesicles are developed when a part of the membrane nips off.

vesicles
What is the vesicular formation membrane bound sac called?
These are called vesicles and they transport various substance into the cell and out of the cell.
Can two vesicles fuse?
Yes, two vesicles can fuse. When one vesicle fuses with another one or with part of the cell membrane this is called vesicle fusion.
