Why do most house plants wilt if not watered for several days?

Answer 1

There is more water in the plant than there is in the soil so the plant will attempt to even out the ballence by putting some of the water that is contained inside it into the soil which will inturn cause the plant to wilt because of returning so much water to the soil

Answer 2

Just like humans and many other organisms, plants are mostly made of water. If you are dehydrated, your metabolic processes tend to become slow, and eventually you will die. The biggest reason plants wilt, however is that their skeletal structure is made up of really tiny tubes, called xylem and phloem, that run throughout the plant that also carry water up the plant and nutrients down through the plant after photosynthesis. The pressure caused by carrying this water up the plant is called turgor pressure.

Basically, the way the water is moved through the plant is through tiny, generally microscopic pores, called stomata, on the leaves that open and close based on environmental conditions. When the stomata are open, a low pressure is created within the xylem tubes, causing water to be absorbed at the roots and to be brought up by the plants- the same principle as drinking through a straw. When a plant is stressed due to a lack of water, these stomata close, making it difficult for the plant to take water up through the plant, leading to loss of turgidity, and eventually to wilting.

Plants wilt when not watered because they lose turgidity, which is the pressure of water in their cells that keeps them firm and upright. Without sufficient water, plants are unable to maintain this pressure, causing them to droop. Additionally, wilting can trigger a plant's stress response, leading to further damage if not addressed promptly.
