Clarify how cells and molecules are linked to tissues

Solution

Answer:

Various molecules together are going to from organelles & finally to form cells and cells together to form tissues, a complex multicellular component of organs & organs systems in an organism. These cells are linked to the tissues via cell adhesion molecules, integral membrane receptors, connexins, selectins & integrins and cadherins via either homophillic homophillic binding or heterophillic binding. The cells are going to connect within the tissues via Cell-Matrix Interactions to basal lamina & cell-cell adhesions or gap junctions or focal adhesions as part of combinatorial diversity

Foe example:

Transitional epithelium is a stratified epithelium mainly existing in urothelium, urinary bladder, prostrate and intercellular adhesion is essential for cell to cell communication & these are existing where the epithelial tissues subjecting to traction & pressure. The prominent intercellular adhesions existing in transitional epithelium are occluding junctions (zonula occludens, zonula adherens (existing in prostrate), tight junctions, anchoring adhesive junctions between cells (desmosomes), gap junctions (connexins) between the cells. Some of the junctions are promoting intercellular adhesion in transitional epithelium.
