Question

Plants cannot make their food at night . Why?​

Answer 1

Answer:

When the sun shines, plants make hay, so to speak—that is, they make food, which they then store up for later. Sunlight is required for the work of photosynthesis, the chemical reaction that magically turns air and water into food. At night, plants can’t photosynthesize—it takes a certain level of light to get the process going.

Answer 2

Answer:

Plants make their food through photosynthesis which require sun light water and chlorophyll. Sun light is available at day time not at night. So plant do not make food at night. ... Chlorophyll can make food the plant can use from carbon dioxide water nutrients and energy from sunlight.
