1) selectively permeable = differentially permeable
上wikipedia搵既，因為BIO書只係得differentially permeable
A semipermeable membrane, also termed a
selectively permeable membrane, a partially permeable membrane or a
differentially permeable membrane, is a membrane which will allow certain molecules or ions to pass through it by diffusion and occasionally specialised "facilitated diffusion".
2) 冇錯！Dead cells係會allow molecules pass through them freely, 所以dead cells are not differentially permeable.
