Potatoe plastids, which store starch, are known as
Correct answer: B. Amyloplasts
- A. Paramylum
- B. Amyloplasts
- C. Leucoplasts
- D. Glycoplasts
Explanation
The correct answer is Amyloplasts. These are specialized plastids within plant cells that synthesize and store starch granules. They are particularly abundant in storage tissues like those found in potato tubers. Paramylum is not a plant plastid but a starch-like compound found in some algae and protozoans. Leucoplasts are a broader category of plastids that store various substances, but they are not exclusively associated with starch storage. Glycoplasts do not exist and are not relevant to the question.

About Cytoplasmic Organelles
Cytoplasmic organelles are the specialized structures suspended in cytoplasm, including mitochondria, ribosomes, endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles and centrosomes. Questions compare their structures and functions in animal and plant cells, including chloroplasts and the role of the endomembrane system in transport and secretion.
