MCQ on Cellulose Biosynthesis in Plants

MCQ on Cellulose Synthesis in Plants: Cellulose is a carbohydrate (polysaccharide) composed of glucose molecules, serving as a structural component in plant cell walls. Cellulose biosynthesis in plants primarily occurs in the plasma membrane, where cellulose synthase enzymes (CESA) assemble glucose molecules into cellulose chains. These chains then form microfibrils, providing structural integrity to plant cell walls, critical for plant growth and support.

Cellulose synthesis occurs at the _______ of the cell, where cellulose synthase complexes align to form microfibrils.

Which of the following is an essential cofactor for cellulose synthesis?

The process of cellulose synthesis is tightly regulated by various factors, including:

Cellulose synthesis is critical for the growth and development of plant cells, especially in the:

In the plant cell wall, cellulose microfibrils are embedded in a matrix of other polysaccharides and proteins. This matrix is known as the:

Cellulose synthesis is a highly energy-demanding process. The energy required for this synthesis comes from:

The orientation and arrangement of cellulose microfibrils in the cell wall contribute to the overall strength and rigidity of the cell. This strength is essential for providing support and protection to the plant. What is the primary function of cellulose in the cell wall?
