Bulk Transport
The bulk transport of molecules consists of two processes, including
1. Endocytosis: This is a type of movement in which cells take up molecules from the environment. This further involves three processes, including:
- Phagocytosis: the engulfment of large particles from outside the environment.
- Pinocytosis: transportation of extracellular liquid along with dissolved substances.
- Receptor-mediated endocytosis: transportation of specific molecules after binding to the receptors.

2. Exocytosis: It is a process in which vesicles present in the cell fuse with a plasma membrane and release their content into the outer environment.

Transport Across Cell Membrane
Transport across the cell membrane is a special process that occurs via the cell membrane. The cell membrane keeps the internal and external environment separate and allows only specific molecules to transport across it. Transportation of molecules occurs via a specialized process known as active and passive transport. The selection of a molecule transporter depends on the molecule to be transported.
In this article, we will discuss transport system types, mechanisms of transport, active transport, passive transport, bulk transport, examples of transport, and factors influencing these transports.
