During a bright afternoon, what is happening inside the cells of a leaf?

  1. Photosynthesis is running while respiration waits for the dark
  2. Respiration is running while photosynthesis waits for a cooler hour
  3. Photosynthesis has replaced respiration until the sun sets
  4. Photosynthesis and respiration are running at the same timeRespuesta correcta

Explicación

Believing that they alternate leaves no way to explain how a leaf can be releasing and consuming the same gases at once, which is exactly what a lit leaf does.
