Question

When a white carnation is placed in green-colored water, it turns green. Why?

- The central vacuoles in its cells fill with green water.
- The ribosomes in the cell start making green proteins.
- It grows more chloroplasts in its petals.
- *Its petals reflect light from the green water.*

Answer 1

A white carnation turns green in colored water because the central vacuole in its cells absorbs the green water, changing the color of the petals, not because of new chloroplasts or ribosomal activity.

Step-by-step explanation:

When a white carnation is placed in green-colored water, it turns green because the central vacuole in its cells fills with the green water. The plant cell wall provides structure and support, while the central vacuole plays a critical role in maintaining turgor pressure and can expand to increase cell size without more cytoplasm production. This expansion allows the vacuole to fill with the green water, leading to the change in color observed in the petals.

Chloroplasts, on the other hand, contain the green pigment chlorophyll which is used in photosynthesis. This green coloration is typically due to the chlorophyll within chloroplasts and is not related to the pigment absorbed from the water in this scenario.
