The biological needs of plants and animals affect their cells' protein content, but the story goes deeper than that.

(A) In a cell, motility is initiated by an actin-dependent protrusion of the cell’s leading edge, which is composed of armlike structures called lamellipodia and filopodia. These protrusive ...

In turn, the cytoskeleton relies on a type of actin protein, called filamentous or F-actin. It forms networks of thin, flexible filaments that affect the shape, stiffness, and movement of cells.
