If a person has undergone a painful procedure and was not given any relief this area will be activated and will be able to be detected on a PET scan. On the contrary, if one has received pain relief this will not be the case. So, an active cingulate cortex will be observed on a PET scan for a subject in pain.
Answer:
The correct answer is - cell wall made up of cellulose that makes it crunchy.

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.
