Can the plant's cell wall burst if it is too full of water molecules? If so, why, how, and what would the plant and an individual cell look like? Also, is that why cut flowers wilt and die?
Answers
When plants are placed in hypertonic solutions, their vacuoles shrink and no longer provide enough pressure to keep the plant from wilting. Because of their rigidity, the cell walls keep their rectangular shape but are less plump. In contrast, animal cells lack a cell wall, and so they shrivel up like raisins.
Yes, because due to the endosmosis. Which means - the inward diffusion of water molecules when the cell is placed in hypotonic solution.
The cells are likely to burst due to more turgor pressure and less wall pressure acts on the cell.
The cells is in turgid state and the cell is fully distended.
The cut flowers die due to the loss of cell sap which is hypertonic in state and which helps in the inward diffusion of water hence when the flower is cut the cell sap escapes and hence the flower cannot retain water through endosmosis and become flaccid and at last dies.
