This is a loaded question. It can be due to micro or macronutrient deficiency, lack of water, too much sunlight, high salinity, infection, etc. The mechanical part of wilting is due to cells in the plant's leaves losing water due to the lowering of turgor pressure (essentially a lack of water causing the cells to deflate like a balloon losing air.)
A lack of sun, water, or Carbon Dioxide, because those three are necessary for plants to perform photosynthesis, which makes food for plants. Or if the soil was contaminated with something toxic.
Plants may become stressed or wilt if they are exposed to too much air, which can lead to excessive transpiration and dehydration. In extreme cases, prolonged exposure to high levels of air circulation can damage the plant's leaves and cause them to dry out or die.
Plants that grow in LEAVES are KATAKA-TAKA plants
A wilt disease is any number of diseases that affect the vascular system of plants. Attacks by fungi, bacteria, and nematodes can cause rapid killing of plants, large tree branches or even entire trees.Wilt diseases in woody plants tend to fall into two major categories, those that start with the branches and those that start with the roots. Those that start with the branches most often start with pathogens that feed on the leaves or bark, those that start with the roots start with wounding or direct entry by the pathogen into the roots, some are spread from one plant to another by way of root grafts.[1]Pathogens that cause wilting diseases invade the vascular vessels and cause the xylem to fail to transport water to the foliage, thus causing wilting of stems and leaves.Source Wikipedia
plants but not animals
"Wilt" is the form of the word "will" which goes with the pronoun "thou". Indeed with only a dozen exceptions, this word is always found immediately after or (in the case of questions) immediately before the word "thou". If you have already figured out that "thou" corresponds to "you" used for a single person, then you can also see that "thou wilt" is exactly the same as "you will".
Cucumber leaves may wilt in the sun due to excessive heat and dehydration. The intense sunlight can cause the leaves to lose water faster than they can absorb it, leading to wilting. Providing shade or watering the plants more frequently can help prevent this issue.
the wilting of leaves take place in hot summer days because of excess transpiration.the process of transpiration take place in stomata which is present in leaves of plant.in order to excess transpiration plants wilt their leaves
They can and do
when plants don't have water, they wilt

they dry out without water. you would wilt if you did not drink any fluids
They will wilt faster w/o water.
Salts will cause water to diffuse out of plant vacuoles, leading their cells to become flaccid. Thus, the plant will wilt.
Defoliants are chemicals which cause plants to lose their leaves.
The obvious one is lack of water, but if the plants do not recover when watered there are a multitude of other reasons. Viruses and diseases are common causes, in which case the plants need to be pulled up and destroyed to prevent the spread of infection. Also, grubs can bore into individual stems and cause them to wilt.
