(Choice A)
A
Guard cells contain proteins which promote the formation of large starch granules, while storage parenchyma cells do not.

(Choice B)
B
Guard cells and storage parenchyma cells contain the same proteins, but the cells are different due to their roles in photosynthesis.

(Choice C)
C
Guard cells and storage parenchyma cells each make a different set of proteins, which determines each cell type’s structure and function.

Final answer:

Guard cells control the opening of stomata and have proteins that regulate this process, while storage parenchyma cells are involved in storing starch and have different proteins that support this function. The proteins produced by each cell type determine their distinct structures and functions. Option c

Step-by-step explanation:

The guard cells and storage parenchyma cells in plants have different functions, which are determined by the specific proteins they produce. While both types of cells are important for a plant's physiology, they serve distinct roles. Guard cells are specialized cells that control the opening and closing of stomata, regulating gas exchange and water vapor movement in a plant. As part of their function, they may contain proteins that respond to environmental signals to open or close the stomatal pore.

On the other hand, storage parenchyma cells are more generalized plant cells that serve multiple purposes including photosynthesis, healing, and particularly starch storage for the plant's use. The presence of large starch granules within these cells highlights their role in storage. These cells have the necessary proteins for storing starch, and this is directly related to their structure and function.

Therefore, the correct choice that best describes why guard cells and storage parenchyma cells are different is (Choice C): Guard cells and storage parenchyma cells each make a different set of proteins, which determines each cell type’s structure and function. Option c

Answer:

C. Guard cells and storage parenchyma cells each make a different set of proteins, which determines each cell type's structure and function.

Explanation

Both of these are two types of specialized cells that make specific combinations of proteins, which allows them to have unique structures and functions.
