There are 2 processes by whicha cell can get what it needs to live. These are 1) Active transport where the cell must expend some energy to move something into the cell (like food molecules) and out of the cell (like waste). The other 2) diffusion/osmosis. Diffusion is a process where things move from areas of higher concentration to areas of lower concentration without expending any energy, like the smell of bacon cooking in a kitchen filling an entire house. Try dropping a drop of food coloring into a glass of water and, without stirring, check it a few hours later. Osmosis is the diffusion of water.

What are the key differences between cadherin and integrin in terms of their functions and mechanisms of cell adhesion?
Cadherins are cell adhesion proteins that mediate calcium-dependent cell-cell adhesion, while integrins are cell adhesion receptors that mediate cell-matrix adhesion. Cadherins are involved in homophilic interactions between cells of the same type, while integrins are involved in heterophilic interactions between cells and the extracellular matrix. Cadherins form adherens junctions, while integrins form focal adhesions.
What are the 2 mechanisms involved when nutrient enter the bloodstream?
The two main mechanisms involved when nutrients enter the bloodstream are passive diffusion and active transport. Passive diffusion allows small molecules to move across the cell membrane from an area of high concentration to low concentration, while active transport requires energy to move molecules against a concentration gradient.
How did scientists understand cell development?
Scientists have studied cell development by observing the growth and differentiation of cells under different conditions in the laboratory. They have also used advanced imaging techniques to track the changes in cells over time. By understanding the molecular mechanisms involved in cell development, scientists have gained insights into the processes that control how cells mature and specialize into different cell types.
How is glucose transported into the cell and what mechanisms are involved in this process?
Glucose is transported into the cell through a process called facilitated diffusion. This process involves the use of specific proteins called glucose transporters, such as GLUT proteins, which help move glucose across the cell membrane. These transporters bind to glucose molecules and facilitate their passage into the cell, allowing for the uptake of glucose for energy production.
What types of transport mechanisms through the cell membrane are passive?
diffusion, facilitated diffusion, and osmosis

What are the control mechanisms involved in regulating the cell cycle and mitosis?
The signal that Signals the end of Growth phase and thusly the initiation of S-phase is generated when the Cell reaches a certain 'critical' size.
What are the principles involved in inversion of sucrose?
The principles that are involved in inversion of sucrose are the basic mechanisms for enzyme catalyzed reactions. These mechanisms were first proposed by Michaelis and Menten in 1913.
What affects the rate of diffusions?
Temperature, Concentration and size of molecules :)
What are Diffusions?
Diffusions refer to the spread of a substance or concept from an area of high concentration to an area of low concentration. In the context of technology, diffusions can also refer to the adoption and implementation of new technologies or innovations within a population or group.
What are few examples of cultural diffusions?

Is sugar a osmosis passive transport or active transport?
Sugar is typically transported across a cell membrane using passive transport mechanisms like facilitated diffusion or simple diffusion. These processes do not require energy input from the cell. However, in some cases, active transport mechanisms such as the sodium-glucose cotransporter may be involved when sugars need to be transported against their concentration gradient, requiring energy.
