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.
Diffusion in cells involves the movement of molecules from an area of high concentration to an area of low concentration. This process can occur through the cell membrane directly or with the help of transport proteins. Factors such as concentration gradient, temperature, and membrane permeability influence the rate of diffusion in cells.

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.
What types of transport mechanisms through the cell membrane are passive?
Passive transport mechanisms through the cell membrane include simple diffusion, facilitated diffusion, and osmosis. These processes do not require energy input from the cell.
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.
What are diffusions of particles through protein channels called?
Diffusion of particles through protein channels is called facilitated diffusion. This process allows specific molecules or ions to pass through the cell membrane with the help of transport proteins.
Centrioles are cell structures involved primarily in?
Centrioles are cell structures primarily involved in organizing the microtubules that make up the cell's cytoskeleton. They are also crucial for cell division, aiding in the formation of the mitotic spindle that helps separate chromosomes during cell division.
Explain the mechanisms involved in disrupting body systems?
Explain the mechanisms involved in disrupting body systems?
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?
Does anyone know what an educational facility is???
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.

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.
What is involved in cell to cell recognition?
Glycoproteins.
What is involved in cell-to-cell recognition?
mitochondria
What are the types of diffusions?
In Biology there are three types of diffusion. There are simple, channel, and facilitated diffusion.
What type of cell is involved in meiosis?
Gametes are involved.
