Photosynthesis & Plant Respiration: Rate Effects

Click For Summary
SUMMARY

The discussion clarifies that a plant's respiration rate does not increase during photosynthesis. Instead, photosynthesis builds energy supplies, while respiration rates are influenced by temperature, soil moisture, plant health, and age. Under optimal conditions, photosynthesis occurs at a rate 5 to 10 times greater than respiration during daylight. If respiration exceeds photosynthesis for an extended period, the plant will cease growth and eventually decline.

PREREQUISITES
  • Understanding of photosynthesis and respiration processes in plants
  • Knowledge of environmental factors affecting plant growth
  • Familiarity with plant biology terminology
  • Basic concepts of plant health assessment
NEXT STEPS
  • Research the effects of temperature on plant respiration rates
  • Explore soil moisture management techniques for optimal plant health
  • Study the impact of plant age on respiration and growth
  • Investigate the relationship between photosynthesis and respiration in different plant species
USEFUL FOR

Botanists, horticulturists, environmental scientists, and anyone interested in plant physiology and growth optimization will benefit from this discussion.

will the plant's respiration rate increasing while the plant is taking photosynthesis?
 
Biology news on Phys.org
The plant will not likely increase its respiration rate during photosyntheis. Photosynthesis is when the plant build up energyn supply. These follwong elements will have an influence on the respiration rate during photosynthesis:
temperature - increase in temperature leads to an increase in respiration
moisture in the soil/medium
health status of the plant
age of the plant - young plants undergo higher respiration rates than older plants

During the day (the light period) photosynthesis under favorable conditions typically proceeds at a rate 5X - 10X that of respiration. Always remember that that if respiration rate exceeds photosynthesis rate for an extended period the plant will stop growing and slowly decline and die.
