The correct answer is Heliophytes

Concept:

  • Plants that are adapted to high intensity of light are known as heliophytes.
  • Heliophytes are often found in environments where sunlight is abundant, such as open fields, deserts, and high-altitude regions.
  • These plants have developed specific physiological and morphological adaptations to thrive in strong light conditions.

Explanation:

  • Heliophytes: These plants are adapted to grow in environments with high light intensity. They have features like thick leaves, reduced leaf area, and specialized pigments to protect against intense sunlight. Examples include many types of cacti and some grasses.
  • Sciophytes: These are shade-loving plants, adapted to low light conditions. They typically have larger, thinner leaves to capture more light. Examples include ferns and many understory plants in forests.
  • Halophytes: These plants are adapted to grow in saline environments, such as salt marshes and mangroves. They have specialized mechanisms to deal with high salt concentrations. Examples include saltbush and mangrove species.
  • Epiphytes: These are plants that grow on other plants for physical support. They are not parasitic and obtain nutrients and moisture from the air and rain. Examples include orchids and bromeliads.
