Cell Wall Composition in Cells

What is the primary component of the cell wall in certain cells like plants and bacteria?

A) Ribosomes

B) Polysaccharides

C) Chlorophyll

D) Glucose

Answer:

The primary component of the cell wall in certain cells like plants and bacteria is polysaccharides.

The cell wall is a key structural feature found in specific cells, such as plants and bacteria. It provides strength and support to the cells, helping them maintain their shape and protect their internal environment. One of the main components of the cell wall is polysaccharides.

In plants, the cell wall is predominantly composed of a polysaccharide called cellulose. Cellulose is a complex carbohydrate made up of glucose monomers linked together by bonds. This arrangement gives cellulose its strength and rigidity, making it an essential component in plant cell walls.

While substances like ribosomes, glucose, and chlorophyll are vital for various cellular functions, they are not the primary components of the cell wall. Ribosomes are responsible for protein synthesis, glucose is a source of energy, and chlorophyll is a pigment involved in photosynthesis. However, when it comes to the cell wall, polysaccharides play a central role in providing structural integrity.
