Exocytosis!! :)
Bulk transport in cells is the movement of large quantities of molecules or particles across the cell membrane at once. This process helps in the efficient transport of substances such as proteins, polysaccharides, or even entire organelles. Bulk transport includes both endocytosis (taking in substances) and exocytosis (releasing substances).
Bulk transport is in 2 forms, exocytosis and endocytosis. Each of these 2 forms can then be sub divided into phagocytosis (movement of solids) and pinocytosis (movement of liquids) When bulk transport occurs, a phospholipid bilayer membrane merges with the cell membrane, and forces the contents of the vesicle in.out of the cell.

The process of regulating the transport of substances in and out of the cell is called cellular transport. This includes processes like active transport, passive transport, and facilitated diffusion, which help maintain the cell's internal environment by controlling the movement of molecules across the cell membrane. The cell membrane itself plays a crucial role in regulating this transport through various protein channels and pumps.

The process of taking in substances into a cell by surrounding them with the cell membrane is called endocytosis. It involves the formation of vesicles that engulf and transport the substances into the cell. Endocytosis is essential for nutrient uptake and cellular communication.

The cell membrane
Bulk transport involves the movement of large quantities of substances across the cell membrane using transport proteins, such as channel proteins or carrier proteins. This process allows cells to efficiently import or export substances like ions, sugars, and amino acids in response to their metabolic needs. Bulk transport is essential for maintaining cell homeostasis and facilitating cellular processes.
These are called vesicles and they transport various substance into the cell and out of the cell.
The process of moving substances across the cell membrane is called "transport." This can occur through various mechanisms, including passive transport (such as diffusion and osmosis) and active transport, which requires energy to move substances against their concentration gradient. Additionally, facilitated diffusion involves specific transport proteins to help substances cross the membrane. Together, these processes maintain the cell's internal environment and enable communication and nutrient uptake.
