Question

Quizplus · Accepted Answer

The mature plant cell wall and corneal stroma of the chicken embryo both contain adjacent layers of fibers that are arranged perpendicular to each other. The plant cell wall is composed of cellulose and other polysaccharides, while the corneal stroma is composed of collagen and proteoglycans. Therefore, options A, C, and E are incorrect. Option B is not accurate because the fibers in the plant cell wall are typically not parallel.
