Diffusion is the movement of particles from a high concentration to a lower concentration. Using particle theory, imagine that you have a substance i.e perfume. When you spray the perfume at first it is quite strong in one area but weaker in the other area. This is because the particles of the perfume want to spread out to form an equilibruim. So the particles move away from each other so there is a 50/50 ratio of perfum on either side of the room.

*from
when something diffuses, its particles began to gain energy and goes to low concentration from high concentration, when its particles are closely packed
Diffusion is the movement of particles from an area of high concentration to an area of low concentration.
how the diffusion in particles works
Diffusion can also happen in liquids. This is because the particles in liquids can move around each other, which means that eventually they are evenly mixed.
For example, if you drop a little bit of paint into a jar of water the colour will spread slowly through the water by diffusion.
Diffusion in liquids is slower than in gases because the particles in a liquid move more slowly.
Solids
Diffusion does not happen at all in solids because the particles in a solid can only vibrate on the spot, rather than being able to move from place to place.
When chemicals, like the smell of perfume or burning toast, are let loose in a room, the particles mix with the air particles. The particles of smelly gas are free to move quickly in all directions. They eventually spread throughout the whole room. This is called diffusion.
Diffusion in gases is quick because the particles in a gas move quickly. It happens even faster in hot gases.

In endocytosis, molecules or other particles that are too large to enter a cell by diffusion, facilitated diffusion, or active transport are conveyed within a vesicle formed from a section of the cell membrane. This process uses cellular energy.
A theory.
Evolution is a fact. The theory of evolution by natural selection is what you are trying to talk about. When someone says " evolution is just a theory " they are using the vulgar, common sense of the word theory. They mean guess, hunch and the like. The theory of evolution by natural selection is in the scientific sense of the word theory, which means a body of explanatory work supported by myriad lines of converging evidence that has been tested rigouusly and replicated often. Any good dictionary uses this scientific meaning of theory as the primary meaning of the word.
Charles Darwin is known for his work on the theory of evolution.
Diffusion (passive transport) needs no energy to take place, and therefore no need for transport or carrier protiens. Active transport uses carrier protiens, as the cell needs to work against a concentration gradient. This requires energy. Diffusion can take place outside of cells Active transport can't take place outside of cells.

Yes it is
diffusion
The Particle Theory has 4 laws:1) All matter is composed of particles2) These particles have spaces between them3) These particles are always moving4) Particles are attracted to each otherThe theory is used to explain how every day things work. For example dissolving can be explained as the particles are simply rearranging themselves to fit between other particles.*Note the word theory in the title, it is there for a reason. This is purely hypothetical and has not been proven... yet.*Also particles have also been referred to as molecules.
The cell will work but not very well because osmosis and diffusion did not occur but sometimes it will work anyways
It's important because it's the particle that gives everything mass (kinda like weight) in Physics. If this particle doesn't exist, it means that all of the science we have relied on so far in Physics, is wrong. This includes Einstein's General Theory of Relativity, or the greatest work Einstein is known for (E=mc2). That's why it's important.
No, osmosis is a type of diffusion. Diffusion never requires work. Osmosis occurs when water seeks equilibrium. The water will naturally try to have the same amount of solvents in it without work from the cell. You can do osmosis experiments using a dialysis bag. Put solvent (such as sugar) in the bag with some water. Then put the bag in a cup of water. Watch what happens :)
Abdus Salam won the Nobel Prize in Physics in 1979 for his contributions to the theory of the unified weak and electromagnetic interaction between elementary particles, now known as the electroweak theory. His work helped establish the Standard Model of particle physics.
Cecilia Laurente is known for her work in the field of nursing. In her theory of nursing practice, she emphasized effective communication and championed using the family as an entry point to help a patient.
Curium is a strong alpha particle emitter and can be used as alpha particle source or in isotopic heat generators.
