Wheat, whose meristematic leaves and stems are sheltered from direct light by upper leaves and leaf sheathes (erectophile morphology, common to grasses and most monocots, but not all monocots).
Both lettuce and soybean, whose meristematic cells in expanding leaves and stems are 'exposed' (planophile morphology, common to dicots and a few monocots),

Erectophile or planophile?
erectophile (grass), planophile(water cress) or with edible leaves.
What is the importance of wilting?
Advantages of Wilting in Plants Though wilting is not considered good, there are few advantages. Wilting helps in reducing the rate of transpiration hence allow plants to conserve water and this prevents plant from over exhaustion in dry seasons as transpiration activities stops. Wilting also serves to reduce water loss, as it makes the leaves expose less surface area by modifying the leaf angle distribution of the plant (or canopy) towards more erectophile conditions. It develops drought resisting character in plant for survival.
What is wilting?
Wilting refers to the loss of rigidity of non-woody parts of plants. This occurs when the turgor pressure in non-lignified plant cells falls towards zero, as a result of diminished water in the cells. The process of wilting modifies the leaf angle distribution of the plant (or canopy) towards more erectophile conditions. Lower water availability may result from: drought conditions, where the soil moisture drops below conditions most favorable for plant functioning; high salinity, which causes water to diffuse from the plant cells and induce shrinkage; saturated soil conditions, where roots are unable to obtain sufficient oxygen for cellular respiration, and so are unable to transport water into the plant; or bacteria or fungi that clog the plant's vascular system. Wilting diminishes the plant's ability to transpire and grow. Permanent wilting leads to plant death. Symptoms of wilting and blights resemble one another. In woody plants, reduced water availability leads to cavitation of the xylem. Wilting occurs in plants such as Balsam and tulasi.
