Answers
Answer:
The connective tissue is a tissue that fills the interstices (spaces) between more specialized elements and serves to hold them together and support them. It is characterized by few cells and large amounts of extracellular matrix (extracellular materials) that separate cells from one another.
The extracellular matrix has three major components: protein fibres, ground substance and fluid.
The protein fibres that form the connective are collagen fibres, reticular fibres and elastic fibres.
Collagen fibres are made of collagen (the most abundant protein in the body). They are tough and flexible but resist stretching. They are often called white fibres because fresh collagen fibres have a glistening white appearance as seen in tendons. Tendons, ligaments and the dermis are made mainly of collagen. They are also found in the matrix of cartilages and bones.

Answer:
Loose connective tissue:
The cells in the matrix are widely distributed and the fibres are loosely woven.
It generally connects and support various tissues and organs and helps them to resist strain and displacement.
types-
Areolar connective tissue
Adipose connective tissue
Reticular tissue
II. Dense (fibrous) connective tissue:
The fibres dominate over the cells and the matrix in quantity.
The fibres may be regularly or irregularly arranged
types:
White fibrous tissue ( tendon and sheath)
Yellow elastic tissue (Ligament
