Answer 1

Connective tissues are the most abundant and widely distributed tissues in animals. These tissues help to link and provide support to other tissues and organs throughout the body. These range from soft to specialised tissues such as cartilage, bone, adipose and blood. Except for blood, the cells of connective tissue secrete collagen fibres, which are made of protein. These fibres provide strength, elasticity and flexibility to the tissue. The cells of connective tissue also secrete matrix or ground substance. Connective tissues are categorised into three types – loose connective, dense connective and specialised connective.
