Answer :
The word "heliotropic" is made up of two parts: "helio-" which is related to the sun or sunlight, and "-tropic" which means turning. Therefore, "heliotropic" refers to plants that swivel to face the sun. These plants have a tendency to track the movement of the sun throughout the day by turning their leaves or flowers to maximize their exposure to sunlight for photosynthesis.
An example of a heliotropic plant is the sunflower. Sunflowers are known for their heliotropic behavior, as their flower heads track the movement of the sun from east to west during the day. This movement is known as heliotropism, allowing the plant to receive optimal sunlight for its growth and development.
In summary, when you encounter the term "heliotropic" in relation to plants, remember that it describes their ability to turn and orient themselves towards the sun to capture the sunlight they need for essential processes like photosynthesis.
