Which is the hardest animal tissue?

Your teeth contain the hardest substance in the human body — your enamel. Bones aren’t quite as hard as enamel, but they rank closely on the hardness scale. Other parts of your body (like muscles, ligaments, and tendons) are incredibly strong, but don’t come close to the mineral-based tissue in your teeth and bones.

What are bones composed of?

Bones are made of connective tissue reinforced with calcium and specialised bone cells. Most bones also contain bone marrow, where blood cells are made.

Is cartilage a hard tissue?

It is not as hard and rigid as bone, but it is much stiffer and much less flexible than muscle. The matrix of cartilage is made up of glycosaminoglycans, proteoglycans, collagen fibers and, sometimes, elastin. Because of its rigidity, cartilage often serves the purpose of holding tubes open in the body.

What makes a meristematic tissue a permanent tissue?

A meristematic tissue is a group of cells that are in a continuous state of division or retain their power of division. Permanent tissues are composed of mature cells that, after undergoing complete growth, have assumed a definite shape, size and function and have temporarily or permanently lost the power of division.
