HHMI researchers suggest that defective cell transport may play a role in Alzheimer’s disease. Over the last few years, scientists have been successful in identifying genes implicated in Alzheimer’s ...
In a new Nature Communications study, scientists have developed a novel method for artificial cells to interact with their ...
their surface area — and thus their ability to both take in nutrients and transport electrons — does not increase to the same degree as their volume. As a result, prokaryotic cells tend to be ...
Xylem cells lose their end walls so they can form continuous tubes almost like pipes to transport that water up to stems and leaves.Palisade or leaf cells live right beneath the surface of leaves.
In pure water, the cell contents (the cytoplasm and vacuole) push against the cell wall and the cell becomes turgid . Fully turgid cells support the stems of non-woody plants. In a very ...
The ability to maintain concentration gradients and sometimes move materials against them is vital to cell health and maintenance. Thanks to membrane barriers and transport proteins, the cell can ...
