The rate of photosynthesis decreases in a wilted herbaceous plant because the
enzymes in the leaf were denatured
chlorophyll in the leaves was not broken down
amount of light reaching the plant was reduced
amount of carbon dioxide entering the leaf decrease.
Penjelasan
Wilting occurs when a plant loses more water through transpiration than it absorbs from the soil.To prevent further water loss, the stomata on the leaves close. When the stomata are closed,CO\(_2\) can't enter the leaf. CO\(_2\) is essential for photosynthesis, which produces glucose and oxygen.
