Substances that move into and out of cells by diffusion include oxygen, carbon dioxide, and small non-polar molecules like water and lipid-soluble molecules. Diffusion is a passive process where molecules move from an area of higher concentration to an area of lower concentration to reach equilibrium. This process does not require energy input from the cell and is essential for maintaining cellular homeostasis.
Substances enter and leave cells through processes such as diffusion, facilitated diffusion, active transport, and endocytosis/exocytosis. Once inside the cell, substances can become distributed within cells through diffusion, cytoplasmic streaming, vesicular transport, and interactions with organelles.
Diffusion and osmosis are processes by which substances move into and out of cells. As cell size increases, the distance that substances must diffuse across also increases, making it harder for cells to efficiently exchange materials. Additionally, larger cells may struggle to maintain proper osmotic balance due to increased demand on their membrane and organelles.
Active transport and facilitated diffusion are both mechanisms used by cells to move substances across the cell membrane. Both processes require the use of specific proteins embedded in the cell membrane to facilitate the movement of substances. However, the key difference between the two is that active transport requires energy input from the cell to move substances against their concentration gradient, while facilitated diffusion does not require energy and moves substances down their concentration gradient.
The cell cotains phospholipids ,proteins , and carbohydrates. Carbohydrates can be attached to either the phospholipids or the proteins in the cell membrane. Sometimes carbohydrates (sugars) are attached to cell membrane phospholipids and to cell membrane proteins
Facilitated diffusion and active transport are both ways that substances move across the cell membrane, but they differ in their mechanisms. Facilitated diffusion uses protein channels to help substances passively move from areas of high concentration to low concentration, while active transport requires energy to move substances against their concentration gradient using protein pumps.
Substances in Spirogyra move into cells through a process called passive diffusion. Spirogyra cells have a cell wall made of cellulose that is freely permeable to water and dissolved substances. This allows nutrients and waste to move in and out of the cells easily.
Substances typically move across capillaries via diffusion.

They move in a bunch mixed together to form or create a substance stronger or sometimes more lethal in a way that is an example of cultural diffusion or chemical diffusion

Diffusion is the methods that leave cells. Diffusion also has to have cellular energy.
