semi permeable membranes
Selectively permeable means that only certain objects can pass through. I've encountered that phrase in cell Biology, when talking about cell membranes. The cell membrane is made of phospholipids that only allow certain substances through. Water can pass through because the molecules are small enough to pass through small holes in the membrane. Other molecules, such as sodium or potassium, can be transported using protiens.
it can keep the cell from dying if if the wrong molecules come through
The cell membrane will only allow certain molecules access. For example, glucose molecules are too large to pass through the cell membrane without undergoing endocytosis, but water molecules can easily pass through the cell membrane.
I semi-permeable membrane is a membrane when only certain substances can pass through it.it is a membrane that will only allow certain molecules through it . in general oxygen , food and water are allowed to enter ; waste products are allowed to exit and harmful substances are kept out. hope this helps.
Will only allow something of a certain size or with certain characteristics to pass through.
the membrane may only allow small particles or may only allow polar/nonpolar molecules, hydrophobic vs hydrophyllic molecules
In Biology, a selective permeable cell means the cell only allows certain molecules to pass through. This concept was first introduced to understand the process of osmosis, where solute molecules move along a concentration gradient through a semi permeable membrane (also known as a selectively permeable membrane) Cells allow water molecules and small ions to pass through their membranes without the expenditure of energy.
The cell membrane only allows certain molecules through.
Semi- Permeable
cytoplasmicdetoxil also known as CYDFJ
It allows only certain molecules to pass through.
The term differentially permeable refers to a membrane or barrier that allows specific molecules or ions to pass through while preventing others from passing. It is also known as selectively permeable or semipermeable. This property is essential for maintaining the balance of substances within cells and regulating the movement of molecules across biological barriers.
