Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike ...

A plasma membrane is permeable to specific molecules that a cell needs. Transport proteins in the cell membrane allow for selective passage of specific molecules from the external environment.

The Visking tubing is the selectively permeable membrane. Water moves by osmosis from the high water concentration (dilute solution) in the beaker into the low water concentration (concentrated ...

Its main purpose is to resist hydrostatic pressure exerted by moisture in the liquid state. Waterproofing membranes consist of waterproof plastic, rubber, or coated-fabric materials. The materials are ...

This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...

Die Begriffe "Bio" und "Öko" sind seit 1993 gesetzlich geschützt. Wer mit ihnen wirbt, muss die Voraussetzungen dafür erfüllen: nämlich die Vorgaben der EG-Öko-Verordnung. Diese schreibt unter anderem ...

Nov. 12, 2024 — Researchers have found that the way DNA is packaged in cells can directly impact how fast DNA itself is copied during cell division. They discovered that DNA packaging sends ...

The ability to fission membranes in cells was previously attributed solely to certain proteins. In a new publication in ...
