In the start of the light cycle, light-dependent reactions harness energy from the sun in order to create chemical bonds. These bonds are known as ATP and NADPH. These are the molecules that carry energy which are made in the stroma. The stroma is where the Calvin cycle takes place.
 
        
             
        
        
        
The differences are animal cells are rectangular whereas plant cells are rectangular. Plant cells have a digit cell wall called that surrounds the cell membrane. Animal Cells do not have cell membranes.
        
                    
             
        
        
        
Answer:
Integrin molecules serve as stable, permanent anchors that anchor a cell to the extracellular matrix.
Explanation:
Integrins are transmembrane protein receptors that attach the cell cytoskeleton to the extracellular matrix (ECM) in animal cells. These glycoproteins (integrins) are highly dynamic heterodimeric molecules that anchor cells in their position and transduce signals into and out of cells. Integrin-ligand binding activates signaling pathways that are involved in fundamental cellular functions including, among others, organization of the cell cytoskeleton, cell migration, regulation of the cell cycle, etc.
