Advanced Cell Transport Edpuzzle
The process of a solute being dissolved in a solvent is called a solution. An example of this is sugar being dissolved in tea. Concentration refers to the relative amount of solute that is dissolved in a solvent. This can be seen when there is a greater concentration of sugar present in a solution, making it hypertonic, and a lower concentration of sugar in a solution, making it hypotonic.
Cell Transport Edpuzzle Answers
Passive transport involves the movement of molecules across the cell membrane without the need for energy. This includes simple diffusion, facilitated diffusion, and osmosis. These processes allow small molecules to move through the cell membrane from an area of high concentration to an area of low concentration in order to achieve homeostasis.
Active transport, on the other hand, requires energy. This type of transport allows molecules to move against the concentration gradient, away from homeostasis. Protein pumps, endocytosis, and exocytosis are all examples of active transport processes.
Inside the Cell Membrane Edpuzzle Answers
Within the cell membrane, there are hydrophilic heads and hydrophobic tails of phospholipids. Different types of transport, such as simple diffusion, facilitated diffusion, osmosis, and active transport, move substances in specific directions across the membrane. For example, simple diffusion allows small molecules to move from an area of high concentration to an area of low concentration without using energy.

Facilitated diffusion involves larger molecules moving through a protein channel, while osmosis involves the movement of water in order to reach homeostasis. Active transport processes, such as protein pumps, endocytosis, and exocytosis, all require energy and allow substances to move against the concentration gradient in order to maintain homeostasis.
Passive and Active Transport Edpuzzle Answers
In summary, passive transport processes allow for the movement of molecules without the need for energy, while active transport processes require energy and move molecules against the concentration gradient. Both types of transport are essential for maintaining homeostasis within the cell.
Overall, understanding the types of active and passive transport, as well as the differences between them, is crucial for comprehending the function of the cell membrane and how substances are transported in and out of the cell. This knowledge is fundamental for grasping the complexities of cellular processes and the importance of maintaining cellular homeostasis.
