Populations evolve and individual organisms do not. Evolution occurs through natural selection and survival of the fittest as populations evolve traits that better suit their environment.
Plant types matched with their descriptions
- Hydrophytes - Aquatic plants
- Mesophytes - Plants with habitats that are neither too wet nor too dry
- Xerophytes - Plants with very dry habitats
Hydrophytes are aquatic plants that may be free floating, fully submerged or partly submerged (amphibious) in water. The vascular tissue of hydrophytes is very poorly developed. Examples of hydrophytes are Ottelia, Sagittaria and Utricularia.
Mesophytes are plants that live in habitats that have a moderate supply of water (neither too wet nor too dry. Mesophytes are usually large, fast growing, and have well developed roots and leaves. Examples of mesophytes are clover and maize (corn).
Xerophytes are plants that are able to thrive with very dry habitats where the available soil water is low. Examples of xerophytes are Acacia and Carthamus.
