Differentiate between exo skeleton and Endo skeleton
Exoskeleton:
1. Location: Exoskeleton is an external skeleton that surrounds and protects the body of the organism.
2. Composition: Exoskeleton is typically made of a tough and rigid material such as chitin or calcium carbonate.
3. Function: Exoskeleton provides support, protection, and helps in maintaining shape and structure of the organism's body. It also serves as a site for muscle attachment.
4. Growth: In organisms with exoskeletons, growth often involves the shedding or molting of the old exoskeleton and the formation of a new one.
5. Examples: Arthropods such as insects, crustaceans, and arachnids have exoskeletons.
Endoskeleton:
1. Location: Endoskeleton is an internal skeleton that is located inside the body of the organism.
2. Composition: Endoskeleton is typically made of bones or cartilages, which are hard and provide support and structure to the body.
3. Function: Endoskeleton provides support, protection, and allows for the movement of the organism. It also serves as a site for muscle attachment and helps in the production of blood cells.
4. Growth: In organisms with endoskeletons, growth involves the continuous deposition of new bone or cartilage and the remodeling of existing skeleton.
5. Examples: Vertebrates such as mammals, birds, fish, reptiles, and amphibians have endoskeletons.
