Or animal cells without cell walls could be much bigger than plant cells. Or plant cells with cell walls would be much smaller. Others might tell you that cell size is limited by diffusion rates.

Quantum dots diffuse within living cells in a nearly two-dimensional fashion. This result, which was obtained using a new 3D microscopy technique that can track single particles, sheds fresh light on ...

Although the membrane of the primary cilium in animal cells is continuous with the surrounding ... now find that a septin diffusion barrier at the cilium base provides one way to keep cilia ...

Diffusion is the movement of particles from high to low areas of concentration. Learn how cells use it to transfer substances. How to make a model animal and plant cell Animal and plant cells can ...

including the roles that molecular diffusion gradients have on stem cell signaling pathways along with new modeling tools that describe gradients of nutrients and signaling factors in three ...

Red blood cells have the shape of a flattened disk, generating a broad surface area for the diffusion of oxygen. Since their only purpose is carrying oxygen throughout the body, they lack many ...

This paper seeks to identify the factors which have the greatest effect on gas diffusion rates into animal burrows, and in turn on the maximum size of burrowing animals which may rely on simple burrow ...

It is widely assumed that the majority of pharmaceutical drugs are transported into cells occurs via ‘passive diffusion’ however, the evidence for “y diffusion through the bilayer” occurring ...

This is a cool science phenomenon - Diffusion! Diffusion is an important process happening everywhere: in the cells of our bodies, roots of plants, and even in your dinner prep. So what is diffusion?

"Understanding these mechanisms requires a synthesis of stem cell biology and mass transfer physics, where physical diffusion phenomena affect neurodevelopmental cues that define cell identities ...
