passive transport
The movement of materials across the cell membrane without using cellular energy is called passive transport. The movement of materials against a concentration difference is known as active transport. Active transport requires energy.
Molecular Transport (in cells) is the movement of materials across a cell membrane. The two kinds of Molecular Transport used in organisms are Active Transport and Passive Transport. Active Transport- materials move across the plasma membrane with the use of energy (like Adenosine Triphosphate) Passive Transport- materials move accross the plasma membrane without the use of energy
It's called passive transport for a cell's membrane. (I checked with my science teacher)

The movement of materials across the cell membrane without using cellular energy is called passive transport. The movement of materials against a concentration difference is known as active transport. Active transport requires energy.
Specifically Diffusion, but it is also active transport
The process of moving materials against a concentration gradient is called active transport. Active transport generally uses a protein pump to move molecules from an area of low concentration to an area of high concentration; in order to perform an active transport, the cell must use some of its energy to initiate the reaction.
Transport of Dangerous Goods (TDG)
The types of vascular tissues are called xylem and phloem. Phloem cells transport energy from photosynthesis and xylem transport materials from the roots to the rest of the plant. These plants are called autotrophs.
The bouncing of light is called reflection.
Active Transport
That would be called erosion.
Passive Transport
passive transport
Some fruit seeds are called pits.
