The cell surface membranes of cells of flower, though semi-permeable, allows water to pass through cell via aqua proteins embedded in the membrane.
This is true since water goes from inside of cell to the extracellular environment when water potential inside the cell is higher than water potential outside the cell via process of osmosis (water goes from an area of high water potential down a concentration gradient to an area of low water potential). Cells in the flower became plasmolysed (cell surface membranes tear away from the cell walls) as the volume of water in cell decreases.
Hope this helps! :)
'<span>According to the following diagram, approximately how much time goes by between phase H and phase B? Explain your answer.'
I'll try to explain this as simply as possible. A single moon cycle is 29 and a half days. Each individual cycle takes approximately 3 and a half days to transition to the next phase, so i</span>f you want to know how much time goes by between phase H and phase B, you would multiply 3.5 by however many phases there are between H and B. The answer is approximately 11 or so days.
I hope this helped!
Nitrogen, even though makes for about 78% of our atmosphere, and is by far the most abundant gas in it, we can not use it because it can not be taken out of the atmosphere as it is. If we take nitrogen in the form as it is in the atmosphere it is useless for both humans and plants. It has to go through a process of ''fixation'' first before we can actually use it in our food.
