.2 Even though senescing cells respire at higher rates, their rate of photosynthesis is lower than that of younger, actively growing cells. True or false
True. Senescing cells, which are older and approaching the end of their life cycle, tend to have higher rates of respiration but lower rates of photosynthesis compared to younger, actively growing cells. This is because as cells age, their ability to carry out photosynthesis declines, leading to reduced photosynthetic rates. However, the metabolic activity of senescing cells remains relatively high, resulting in higher rates of respiration.
