The plant on the right must have been the one given a saltwater mixture while the one on the left must have been given pure water.
<h3>Osmosis</h3>
Looking at the attached image closely, one would see that the plant on the right has withered leaves while the leaves of the plant on the left seem to be flourishing.
The plant on the right must have been the one fed with water mixed with salt and here is the reason. Adding water mixed with salt to the soil on which the plant grows will decrease the water potential of the soil relative to the water potential of the plant's root. Thus, water will move from the plant into the soil through the root by osmosis. This will cause the various cells of the plant to become flaccid, and hence, the withered leaves.
On the contrary, the plant on the left must have been fed with pure water. Feeding the soil with pure water will increase the water potential of the soil relative to the water potential of the plant's root. Thus, water will move from the soil into the plant through the root by osmosis. This will cause the various cells of the plant to become turgid, and hence, the flourishing leaves.

#SPJ1
The action or process of fertilizing an egg, female animal, or plant, involving the fusion of male and female gametes to form a zygote. The gametes that participate in fertilisation of plants are the sperm (male), and the egg cell, and in flowering plants a second fertilisation event involves another sperm cell and the central cell which is a second female gamete. In flowering plants there are two sperm from each pollen grain.
