Biology CLEP Prep Practice Exam

Plant cells contain cellulose, a type of carbohydrate found in the cell wall.

RNA, or ribonucleic acid, is responsible for protein synthesis and is not found in the cell wall.

Glucose is a type of sugar and provides energy for the cell, but is not a major component of the cell wall.

Lipids, or fats, are also not typically found in the cell wall of a plant cell.

Instead, lipids are often found in the cell membrane, providing a barrier between the cell and its environment.

Therefore, the correct answer is D, cellulose.

Cellulose is a type of polysaccharide that forms a strong, rigid structure in the cell wall, giving the plant cell its shape and providing support for the plant as it grows.
