Connective tissue binds other tissues together in the organs. Phloem parenchyma   4. Companion cells   3. The cells may be spherical, oval, polygonal or rectangular in shape. Epithelial cells lie on a delicate non-cellular basement membrane which contains a special form of matrix protein, called collagen. The nature of matrix decides the function of connective tissue. Location: They are present in hand, feet and other skeletal muscles. It has great strength but its flexibility is limited. The free end of the cells consists of finger-like projections called microvilli. Xylem is composed of cells of four different types: 1. It results in increase in the hight of the plant, which is called primary growth. It consists of thin-walled living cells. It covers most organs and cavities within the body.
