Plants growing on sand are called as A. chasmophytes B. oxylophytes C. lithophytes D. psammophytes

The correct answer is D. psammophytes.

Psammophytes are plants that are adapted to growing in sandy soils. They have a number of adaptations that help them to survive in these harsh conditions, including:

• Shallow roots: Psammophytes have shallow roots that help them to anchor themselves in the sand and to access water and nutrients.
• Thick, waxy leaves: Psammophyte leaves are often thick and waxy, which helps to reduce water loss.
• Small leaves: Psammophyte leaves are often small, which helps to reduce water loss and to protect the plant from the sun’s harsh rays.
• Cushion-like growth habit: Psammophytes often have a cushion-like growth habit, which helps to protect them from the wind and to trap heat.
• Drought-tolerant: Psammophytes are often drought-tolerant, which means that they can survive in dry conditions.

Some examples of psammophytes include:

• Sea oats: Sea oats are a type of grass that is found on sandy beaches. They have long, thin leaves that help them to trap sand and to prevent erosion.
• Sand verbena: Sand verbena is a type of wildflower that is found on sandy dunes. It has small, pink flowers that bloom in the spring and summer.
• Beach pea: Beach pea is a type of legume that is found on sandy beaches. It has small, white flowers that bloom in the spring and summer.

Psammophytes play an important role in the ecosystem. They help to stabilize sand dunes and to prevent erosion. They also provide food and shelter for a variety of animals.
