Why do crops shrivel up in a drought?

Crops shrivel up in a drought due to a lack of water, which is essential for their growth and survival. Insufficient moisture leads to reduced photosynthesis, stunted growth, and ultimately, cell dehydration. As plants struggle to conserve water, they close their stomata to minimize water loss, further limiting their ability to absorb carbon dioxide and produce energy. This combination of factors results in wilting and reduced yields.
