Pretend to be a green plant and tell me about ur day(make sure it explains photosynthesis) *using all my points*

Answer:

Plants are made up of roots, stems, and leaves, and most produce flowers, fruit, and seeds. ... Using carbon dioxide, water, nutrients, and energy from sunlight, the chlorophyll makes the food that the plant needs. This process is called photosynthesis. During this process, plants release oxygen into the air. During the day, plants soak up sunlight during photosynthesis, the process they use to get energy. But when the sun goes down, plants' opportunity to eat disappears and other physiological processes take over, including energy metabolism and growth. Plants release oxygen during the day in the presence of natural light through the process of photosynthesis. While at night, the plants uptake oxygen and release carbon dioxide, which is called respiration.
