osmosis, 渗透,水流经半透膜,从低渗溶液流向高渗溶液。因为半透膜不允许大分子/离子通过,只允许水分子通过。运的是水。 以上两种都是被动运输,不需要能量。 active transport,主动运输,将分子由低浓度运向高浓度。需要通过细胞膜上特殊的载体蛋白,消耗ATP供能。 具体参看百度百科。请问LZ在哪里上学? 禁言|2楼2009-...
“Diffusion and Osmosis” is an interactive app for students to learn about Active transport, Diffusion and Osmosis, osmosis in plant cell, process of osmosis, diffusion biology in an easy and engrossing way by visualizing the colorful images. It is one of the best educational applications which...
to study cell migration10,16,22,27. These cells consist of a broad and flat lamellipodium in the front and a round cell body in the rear (Fig.1a). Fish keratocytes mainly make two types of motions: mostly persistent migrations and occasionally short turns (Fig. S1). ...
Osmosis:Osmosis might be described as a "sucking pressure" that causes the movement of water when the movement of particles dissolved in the water is impossible. This occurs when a membrane allows water, but not the dissolved particles ("solutes") in question, to pass through it. The driving...
Active transport, Diffusion and Osmosis, osmosis in plant cell, process of osmosis, diffusion biology in an innovative learning method. This app is for students in the age group of 11 - 15 years and is optimized for use in both phones and tablets. “Diffusion and Osmosis” app is students...
It appears that the extracellular environment is hypertonic when compared with the cellular space, and this likely promotes the efflux of water from the cell via osmosis; hence, cells in the monolayer were found to contract following treatment. We have shown that the laser interferometric method ...
