Permeable facts
WebCell walls are fully permeable when it allows tiny molecules inside the cells in the size of 30 to 60 kilo dalton. These tiny molecules can be hydrogen oxide or any nutrient. This is specially for plants as 90% of their nutrient uptake is from water. Though the cell wall, specifically in plants, is completely or fully permeable all time, the ...
