Filopodia are thin projections with parallel bundles of microfilaments. Therefore the leading edge of a crawling cell has parallel bundle microfilaments. While meshes are found between two filopodia and this is known as lamellipodia. Solution Filopodia are thin projections with parallel bundles of microfilaments.
