A gardener forgot to water a potted plant for a day during summer, what will happen to the plant? Do you think it is reversible? If yes, how?
The rate of transpiration is more due to the higher temperature than the absorption of water so this will lead to wilting or losing the plant’s turgidity.
Identify a type of molecular movement which is highly selective and requires special membrane proteins, but does not require energy
