Answers
Answer:
1) The main difference between bone and cartilage are listed below. Bones are the hard, inelastic and a tough organ that forms part of the vertebral skeleton. Cartilage is a soft, elastic and flexible connective tissue that protects the bone from rubbing against each other. Bones are of two types: compact or spongy.
2) A ligament is an elastic band of tissue that connects bone to bone and provides stability to the joint. Cartilage is a soft, gel-like padding between bones that protects joints and facilitates movement.
3)Plant and animal cells have several differences and similarities. For example, animal cells do not have a cell wall or chloroplasts but plant cells do. Animal cells are mostly round and irregular in shape while plant cells have fixed, rectangular shapes.
4) Parenchyma has a thin cell wall of their cells, and are made up of cellulose. Whereas collenchyma cells have an uneven cell wall made up of pectin and hemicellulose. There is a hard and thick cell wall present of the sclerenchyma cells, which is made up of the lignin.
