Which of the following impart a red colour to Rose petals?
Correct answer: C. Chromoplast
- A. Chloroplast
- B. Chlorophyll
- C. Chromoplast
- D. Leucoplast
Explanation
Chromoplasts contain pigments such as carotenoids and can give flowers red, yellow or orange colours. Chloroplasts contain chlorophyll and give green colour, while leucoplasts are generally colourless. Students most likely choose chlorophyll because it is a well-known plant pigment, but chlorophyll produces green rather than red colour.

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.
