Describe two basic types of cell inclusions with examples and differentiate between calcium oxalate and calcium carbonate inclusions in vegetable drugs.

You're on a roll — here are the answers to question 7: 7. a) Two basic types of cell inclusions with one example each: 1. Reserve food materials: These are stored nutrients for the cell. Example: Starch grains* (e.g., in potato cells). 2. Excretory or waste products: These are metabolic by-products that are stored or eliminated. Example: Calcium oxalate crystals* (e.g., in rhubarb or senna leaves). b) Differentiation of calcium oxalate and calcium carbonate cellular inclusions in vegetable drugs: Calcium oxalate and calcium carbonate inclusions can be differentiated by their reactions with acids: Calcium oxalate crystals: These are insoluble in acetic acid but soluble in strong mineral acids* (like hydrochloric acid) without effervescence (no gas bubbles produced). Calcium carbonate crystals: These are soluble in acetic acid and other acids, producing effervescence* (release of carbon dioxide gas, CO_2) due to the decomposition of the carbonate.
