Which organelle forms a membranous system of channels for intracellular transport?
The endoplasmic reticulum (ER) forms a membranous system of channels for intracellular transport. It plays a crucial role in protein and lipid synthesis and transport within the cell.
What are cytosols?
Cytosol is a soluble part of cytoplasm. It forms the ground substance or 'background material' of the cytoplasm. It is located between the cell organelles.
What forms the boundary between the nucleus and cytoplasm?
The boundary between the nucleus and cytoplasm is formed by the nuclear envelope, which consists of two lipid bilayer membranes: the inner and outer nuclear membranes. These membranes are punctuated by nuclear pores that regulate the transport of molecules between the nucleus and the cytoplasm, allowing for the selective exchange of proteins, RNA, and other substances. The nuclear envelope plays a crucial role in maintaining the integrity of the genetic material within the nucleus while facilitating communication with the cytoplasm.
All forms of passive transport depend on what?
All forms of passive transport depend on the movement of molecules or ions across a cell membrane without the use of cellular energy (ATP). This includes processes such as diffusion, osmosis, and facilitated diffusion.
What forms most of a cell?
The Cytoplasm which is mostly water. Cytoplasm
How do plant cells with cell walls divide their cytoplasm?
a new wall forms in between middle of the cytoplasm.
Are endocytosis and exocytosis forms of active or passive transport?
Endocytosis and exocytosis are forms of active transport.
What forms around the two chromosome groups at the end?
Cytoplasm
What forms a tubular communication system within the cytoplasm?
ER
During endocytosis what happens to the pocket in the cell membrane when it breaks loose from the membrane?
When the pocket in the cell membrane breaks loose during endocytosis, it forms a budding vesicle that encloses the material being internalized. This vesicle then pinches off from the membrane and moves into the cytoplasm of the cell to deliver the material to its target destination.
What are the three generic parts of a cell?
The three generic parts of a cell are the cell membrane (or plasma membrane), which forms the outer boundary of the cell, the cytoplasm, which contains various organelles and cellular structures, and the nucleus, which houses the genetic material of the cell in the form of DNA.
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.
