C) inclusions
D) microvilli
E) tight junctions

Question

Quizplus · Accepted Answer

Gap junctions allow small molecules and ions to pass directly from cell to cell, facilitating communication and metabolic cooperation between neighboring cells. Desmosomes are junctions that anchor intermediate filaments and provide structural support, while tight junctions seal the intercellular space, preventing the passage of molecules between cells. Inclusions are insoluble particles, such as pigments, that are stored within cells, and microvilli are membrane extensions that increase the surface area for absorption and secretion.
