The woman inhales oxygen produced by the plant in the process of PHOTOSYNTHESIS,
and she use it inside her body to release energy from the food molecules by the process of RESPIRATION also as a result of respiration Carbon dioxide gas is produced, which she exhales.
That carbon dioxide is absorbed from air by the plant and use it to prepare food from it in the presence of sunlight by the process of PHOTOSYNTHESIS in which oxygen is also produced as byproduct which is then released to air and is then inhaled by the woman again to repeat the cycle.
A) size = (number of minor spaces x 10μm) / number of ocular spaces = (2 x 10) / 1 = 20μm
b)Since the RBC has a size of 8μm and the bacterium 20μm, the bacteria is bigger. The Bacterium is bigger than the RBC by 20μm / 8μm Hence the bacterium is 2.5 times bigger than the RBC.
