Answer:
The correct answer is - cell wall made up of cellulose that makes it crunchy.
Step-by-step explanation:
In plant-based foods, the outer membrane is a cell wall that provides structure and supports the plant to stand erect and protect from the outer environment. The cell wall is mainly composed of cellulose that is a carbohydrate which is comparatively crunchy or tough to the animal protein with a fatty cell membrane that makes it chewier than the crunchy.
The composition of the protective layers of the plant cels and animal cell causes this difference in their texture.
