Passive transport in cells was not discovered by a single individual, as it is a fundamental biological process that has been observed and studied over time. However, early research in the 19th century by scientists such as Thomas Graham, who studied diffusion, contributed to the understanding of how substances move across cell membranes without energy input. The concept of passive transport became more defined with subsequent advancements in cell Biology and membrane studies.
What else can I help you with?
There are two main ways in which molecules are transported into and out of cells - active transport and passive transport. Which of the following statements is true of passive transport?
Carrier proteins are sometimes used during passive transport.
Why do cells prefer to use passive transport instead of active transport?
Cells prefer to use passive transport because it does not require energy input from the cell. Active transport, on the other hand, requires energy in the form of ATP to move molecules against their concentration gradient. Passive transport is more efficient for moving molecules down their concentration gradient.
What cells use active transport?
Energy, versus passive in which energy is not used.
What perform active transport cells use?
Energy, versus passive in which energy is not used.
To perform active transport cells use what?
Energy, versus passive in which energy is not used.

Whats the conclusion that passive transport is easier for cells to complete than active transport?
Active transport requires the cell to expend energy. However passive transport occurs because of a gardient.
Which type of transport is responsible for oxygen entering into blood cells?
Passive
What type of transport does not require energy?
Passive transport does not require energy, as it involves the movement of molecules across a cell membrane without the input of energy. This includes processes such as diffusion, osmosis, and facilitated diffusion.

Is exocytosis considered a form of passive transport?
No, exocytosis is not considered a form of passive transport. It is an active process where cells expel materials by fusing vesicles with the cell membrane.
What are the two general types of transport used by cells to transport materials in and out of the cell?
The two general types of transport used by cells are passive transport, which does not require energy and includes processes like diffusion and osmosis, and active transport, which requires energy and involves processes like protein pumps and vesicle transport.
What cells use active transport?
Energy, versus passive in which energy is not used.
What perform active transport cells use?
Energy, versus passive in which energy is not used.
Is oxygen passive transport?
well oxygen isn't a transport system it is something that can be diffused across the membranes of cells.
Diffusion and osmosis are forms of what?
Diffusion and osmosis are forms of passive transport, which is the movement of particles across a membrane without requiring energy input from the cell.
Is transport proteins active transport or passive transport?
passive
