A cladogram is a chart which demonstrates cladistics. A branch point on a cladogram branches off from a common point in a cladogram, which shows that the two organisms share a common ancestor. Hope this helps! (:
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! :)

The best answer is (3).
Guard cells help regulate water loss by controlling the opening and closing of stomata which facilitates gas exchange and transpiration in plants.
Guard cells are able to control the opening and closing of stomata by changing shape. The guard cells take in potassium ions which causes water to diffuse into them by osmosis. The cells then swell and become bowed. When this happens, they bend way from each other thereby opening the stomata.
When they lose the potassium ions, water diffuses out by osmosis and the cells become flaccid and less bowed thus closing the stomata between them.
