Yes, diffusion can occur without a membrane. It is the process by which molecules move from an area of higher concentration to an area of lower concentration, driven by their kinetic energy. This can happen in any medium, such as gases or liquids, as long as there is a concentration gradient. Membranes can facilitate or regulate diffusion, but they are not a prerequisite for the process to take place.
Diffusion occurs in the leaf to facilitate the movement of gases such as carbon dioxide and oxygen. These gases diffuse in and out of the leaf through small openings called stomata, allowing for photosynthesis and respiration processes to take place effectively. This exchange of gases helps the leaf to obtain the necessary substances for energy production and to release waste products.
Mitochondria are not necessary for the process of diffusion to occur. Diffusion is a passive transport mechanism that allows molecules to move from an area of higher concentration to an area of lower concentration, driven by concentration gradients. This process does not require energy or cellular organelles like mitochondria. However, mitochondria are crucial for cellular respiration and energy production, which can influence other cellular processes.
Genetic change is necessary for natural selection to take place

There must be areas of different concentration.
diffusion takes place in the alveoli
Diffusion happens in every plant and animal cell. It occurs through the membrane of each and every cell in the organism.

Facilitated diffusion is a passive transport process where molecules move across a cell membrane with the help of specific carrier proteins. These carrier proteins are present in the membrane and assist in the movement of molecules like sugars and amino acids down their concentration gradient. Facilitated diffusion occurs in the lipid bilayer of the cell membrane.
Diffusion can take place in any substance, cause diffusion means the mixture of gases . In a perfume shop diffusion takes place
Osmosis and diffusion take place across the plasma membrane, the outer "wall" of the cell. It is considered to be an organelle because it carries out a variety of functions. The cell membrane or plasma membrane is made up of a double layes of phosphorous and lipid molecules, known as the 'phospholipid bilayer'.
Facilitated diffusion depends on specific carrier proteins located in the cell membrane that help transport molecules across the membrane. These carrier proteins are selective and facilitate the movement of specific molecules based on their size, shape, and charge. Additionally, facilitated diffusion relies on the concentration gradient of the molecules to drive their movement across the membrane.
P.I.S.O.- Potassium in Sodium out facilitated diffusion, active transport , and passive transport and simple diffusion.
The conditions necessary for diffusion is firstly a semi permeable membrane, and a concentration gradient for the movement of molecules from higher concentration to lower concentration. The size of the molecules should be small enough to pass easily through the membrane.
if the temp is higher then diffusion take place faster
