Based on the organization of plants and animals at a cellular level, the following is true:
1) Membrane protein complexes that strengthen the adhesion between adjacent cells, like rivets, to protect against pulling forces. - Desmosomes - Animal.
2) Small channels that form across the plasma membranes of adjacent cells; especially important in intercellular communication. - Gap junctions. - Animals.
3) Membrane proteins that create watertight seal between cells. - Tight junctions - Animals.
4) Small channels between cells that are otherwise surrounded by walls; enable movement of water and solutes between cells. - Plasmodesmata - Plant.
5) A polysaccharide that is used to synthesize cell walls, which protect cells and help maintain their shape. - Cellulose - Plant.
6) Long fibers of protein found in the extracellular matrix that provide structural support for cells. - Collagen - Animal.
<h3>Features of plant and animal cells</h3>
Animals are known to desmosomes, gap junctions, tight junctions, and collagen to help cells fulfil their duties and keep the body functioning.
Plants have plasmodesmata, and cellulose which ad the plant by helping cells perform their functions.
