Question

Plants produce ATP in their chloroplasts during photosynthesis. They also produce ATP during respiration. Explain why it is important for plants to produce ATP during respiration in addition to during photosynthesis. (5)

a) Plants produce ATP during respiration to release excess oxygen produced during photosynthesis.
b) Plants use ATP from respiration to convert carbon dioxide into oxygen.
c) ATP from respiration provides energy for essential cellular processes, especially during the night when photosynthesis does not occur.
d) Plants produce ATP during respiration to speed up the rate of photosynthesis.

Answer 1

Plants produce ATP during respiration to provide energy for essential cellular processes, especially at night. Oxygen produced during photosynthesis is used for cellular respiration.

Step-by-step explanation:

Plants produce ATP during respiration to provide energy for essential cellular processes, especially during the night when photosynthesis does not occur. While photosynthesis is responsible for producing glucose and ATP during the day using sunlight, respiration ensures that plants have a constant supply of ATP for cellular activities. It is also worth mentioning that oxygen produced during photosynthesis is used by plants and other organisms for cellular respiration, which in turn releases carbon dioxide.
