The semi permeable membrane is called the blood brain barrier. It allows smaller molecules such as oxygen to enter the brain, and also protects the brain by preventing larger molecules such as toxins to enter.
It is semi permeable [ the cell membrane]
Permeable mean that it is full time. Semi-permeable is when it is only part of the time.
The type of tubing that is semi-permeable is that tubing used for dialysis. It needs to be semi-permeable to switch or remove molecules for different types of diffusion.
The cell membrane is semi-permeable.
Animal cell membranes are a semi-permeable membrane.
No, they are fully permeable, i.e. liquids and other things can pass through them fully. The cell membrane is what's semi permeable.
nope
Semi-permeable. They let some things in, and others out. Typically, nutrients and water are let in, and waste products from cellular metabolism are let out!

semi permeable lets some substances through and impermeable lets no substances through
Semi-permeable means partially permeable. The term semi-permeable is composed of two words -semi and permeable. Semi is prefix in Latin and means half, or incompletely or somewhat. Permeability refers to the quality of diffusion or seeping or penetrating. This quality is generally associated with liquids or gases. Thus, semi-permeable is used to describe something that allows the passage of some substances and blocks other or not required substances.
There is no real difference other than the wording; both semi-permeable and partially-permeable mean the ability to allow some substances to pass.However, OCR examiners for AS Biology have said that you should "not use the term semi-permeable when referring to cell membranes that allow water and other solutes to cross them" but should "refer to them as partially permeable."
