Photosynthesis & Plant Respiration: Rate Effects

AI Thread Summary
During photosynthesis, a plant's respiration rate does not typically increase; instead, photosynthesis builds up the plant's energy supply. Several factors influence respiration during this process, including temperature, soil moisture, plant health, and age. Higher temperatures generally lead to increased respiration rates, while younger plants tend to respire more than older ones. Under optimal conditions, photosynthesis can occur at a rate 5 to 10 times greater than respiration during daylight. If respiration exceeds photosynthesis for an extended period, it can hinder plant growth and lead to decline or death.

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.

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
