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 ...

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 ...

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 ...

These structures intermingle in a crowded aqueous phase known as the cytoplasm, within which diffusion deviates from Brownian motion. Understanding the concept of "cell crowding" and the impact on ...

Key concepts include diffusion, osmosis, and active transport, which allow cells to obtain nutrients and expel waste. The film also covers the significance of proteins, carbohydrates, and fats in ...

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 ...

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 ...

"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 ...
