Explanation:

Cell theory is one of the foundations of biology. The observation of Robert Hooke,Anton Van Leeuewenhoek,Matthias Schleiden,Theodor Schwann,Rudolf Virchow, and others led to the devolepment of the cell theory.
Comparing the physical features of the three types of skeletons
<u>Endoskeleton :</u>
Less Flexible than cartilage
<u>Exoskeleton :</u>
very rigid and hard
<u>Hydrostatic skeletons </u> :
Less rigid and very flexible
<h3>Physical difference of the types of skeletons </h3>
The endoskeleton is the internal skeleton present in vertebrates in the form of bones which enables the movement of animals while supporting the organs of the body to remain in position. they are less flexible when compared to cartilage. Exoskeletons are outer skeletons which protect organisms and also enables them to move freely. They are very rigid and hard.
Hence we can conclude that the comparison between the types of skeletons are as listed above.
