What happens to a plant just as it runs out of water?

When a plant runs out of water, it experiences wilting as cells lose turgor pressure, causing leaves and stems to droop. Photosynthesis slows down or halts due to insufficient water, leading to reduced energy production. The plant may also close its stomata to conserve moisture, which further limits gas exchange and growth. If water is not replenished, prolonged drought can lead to cellular damage and eventually death.
