Plants adapted to open, sunny habitats are

The correct answer is B. Heliophytes.

Heliophytes are plants that are adapted to open, sunny habitats. They have a number of adaptations that allow them to thrive in these conditions, including:

• Large leaves that absorb a lot of sunlight
• A thick cuticle that helps to prevent water loss
• A deep root system that allows them to reach water and nutrients that are deep in the soil
• A high concentration of chlorophyll that allows them to photosynthesize efficiently

Sciophytes are plants that are adapted to shady habitats. They have a number of adaptations that allow them to thrive in these conditions, including:

• Small leaves that do not absorb as much sunlight
• A thin cuticle that allows them to take up water more easily
• A shallow root system that allows them to reach water and nutrients that are close to the surface of the soil
• A lower concentration of chlorophyll that allows them to photosynthesize less efficiently

Mesophytes are plants that are adapted to intermediate light conditions. They do not have the same adaptations as heliophytes or sciophytes, but they can tolerate a range of light conditions.

Epiphytes are plants that grow on other plants, but they do not take nutrients from their host plant. They get their nutrients from the air, rain, and debris that collects on their host plant.
