Eukaryotes Are Organisms That Have Evolved Membrane-bound Organelles Such as Mitochondria.Golgi Apparatus, and in the Case of Plants

Problemas

Eukaryotes are organisms that have evolved membrane-bound organelles such as mitochondria.Golgi apparatus, and in the case of plants chloroplasts. Eukaryotes may be multicellular organisms consisting of many cell types which form different tissue structures. Cell membranes and cell walls are composed of a variety of lipids, proteins, and carbohydrates each which provides structure and function to the eukaryotic cell. Which macromolecule is a primary component of cell walls, and which argument provides evidence for how the structure of this molecule relates to its purpose within the cell wall? A. Lipids are water soluble fatty acids that are the primary component of cell walls; they regulate water uptake by the cell because they form carbon chains. B. Lipids are water insoluble fatty acids and the are the primary component of cell walls; they protect the cell and help maintain its shape because they form carbon rings. C. Carbohydrates like cellulose and chitin are the primary component of cell walls,they repel and prevent excess uptake of water because they form rigid linear carbon chains. D. Carbohydrates like cellulose and chitin are the primary component of cell walls; they protect the cell and help maintain its shape ebecause they form chains of rigid carbon rings.

The correct answer is 'C'. Carbohydrates like cellulose and chitin are the primary component of cell walls, they repel and prevent excess uptake of water because they form rigid linear carbon chains.

Explicación

## Step 1The problem is asking us to identify the primary component of cell walls in eukaryotic cells and explain how the structure of this molecule relates to its function within the cell wall.## Step 2We know that eukaryotic cell walls are primarily composed of carbohydrates, specifically cellulose and chitin. These carbohydrates form rigid linear carbon chains, which provide structural support to the cell.## Step 3Looking at the options, we can see that options A and B are incorrect because they state that lipids are the primary component of cell walls. Lipids are indeed a component of cell membranes, but they are not the primary component of cell walls.## Step 4Options C and D are correct in stating that carbohydrates are the primary component of cell walls. However, option D is incorrect because it states that carbohydrates form chains of rigid carbon rings. This is not accurate; carbohydrates form rigid linear carbon chains, not rings.
