Neighboring plant or fungi cells share a common cell wall, making multicellularity relatively simple; how do animal cells remain connected to one another?

Question

Quizplus · Accepted Answer

Most animals produce a fiber-rich extracellular matrix to which their cells can attach. Unlike plant and fungi cells, animal cells don't share a common cell wall, and they don't extend long interconnecting fibers between nuclei. Instead, many animals produce an extensive extracellular matrix that provides structural support, helps to maintain tissue architecture, and facilitates communication between cells. Fibrous proteins such as collagen, elastin, and fibronectin are the major components of this matrix, and they allow cells to adhere to one another while also providing a scaffold for migration, differentiation, and tissue repair.
