Question

Quizplus · Accepted Answer

When cells make contact with a surface, they send out projections such as filopodia and lamellipodia. These projections help the cell to make increasingly stable attachments to the surface. As the cell establishes more stable attachments, it flattens out to maximize the surface area in contact with the substrate. This allows the cell to adhere more firmly and spread out to explore the surrounding environment.
