Sieve tube
The process is called phagocytosis.
The process you're referring to is called endocytosis. During endocytosis, the cell membrane invaginates, or folds inward, to engulf a molecule, forming a vesicle that transports the molecule into the cell. This mechanism allows cells to uptake large molecules or particles that cannot pass through the membrane directly.
ENDOCYTOSIS
Yes, the cell membrane is made up of two layers of phospholipids called a lipid bilayer. These phospholipids have hydrophobic tails that face inward and hydrophilic heads that face outward, providing the structure of the membrane.
Caldera.
This process is called endocytosis.
The process is called phagocytosis.
The double layer of phospholipids is called the phospholipid bilayer. It forms the basis of every membrane, both the plasma membrane and all internal membranes.The idea that the bilayer has protein molecules embedded in it is the essence of the fluid mosaic model of the cell membrane.
An inward breath is called inhalation. It is the process of breathing in air into the lungs.
