Question

why do plants not need an oxygen carrier like the humans in whom oxygen is carried by haemoglobin? in 40-60words

Answer 1

well plant has a complete different anatomy than humans
they may perform all the similar works excretion,respiration,reproduction but their way of perfoming us different from humans
they do require o2 to get energy but o2 is simply diffused in through stomata and gets directly in the leaf
while in hunans direct o2 cannot be acquired it needs a carrier haemoglobin so that cells can use it up
