The intensity of light had greater impact on the rate of photosynthesis. It was observed that the jar in which the intensity of light was high, large amount of oxygen was produced as compared to the jar in which the intensity of light was low.  
In the process of photosynthesis, oxygen is produced from the carbon dioxide. As the oxygen in the jar increases, the leaf disk rises with in the jar which also signifies the higher oxygen production with higher rate of photosynthesis in presence of high intensity of light.

Answer:
During the development of the fetus, the mechanism by which the mammalian skeletal system gives rise to tissues of the bone is termed as endochondral ossification. Endochondral ossification also plays an essential role at the time of the development of the long bones length, rudimentary generation of the long bones, and healing of bone fractures naturally.  
The following are the steps in the process of endochondral ossification:  
f. The development of the cartilage model.  
b. The calcification of cartilage takes place and the formation of bone collar occurs.  
a. In the diaphysis, the formation of the ossification center takes place.  
c. In the epiphysis, the formation of ossification centers takes place.  
d. Replacement of cartilage takes place by the bone.  
e. Ossification of epiphyseal plates takes place.
