D) Lipids

Answer 1

Cells that form a tissue are held together by Proteins.

The building technologies of animals and plants are different, and each type of organism is formed of many types of tissues, in which the cells are assembled and bound together in different ways. In both animals and plants, however, an essential part is played in most tissues by the extracellular matrix. This complex network of secreted extracellular macromolecules. However, is only half the story. In animals especially, the cells of most tissues are bound directly to one another by cell-cell junctions. The matrix is rich in fibrous polymers, especially collagen. Collagen is a fibrous protein rich in glycine and proline that is a major component of the extracellular matrix and connective tissues.
