Chapter 22: Problem 7

Differentiate between vascular and nonvascular plants.

Short Answer

Expert verified

Vascular plants are a large group with specialized cells for water and nutrient transportation, such as xylem and phloem, that allow them to grow taller and larger. They have well-developed roots, stems, and leaves. Nonvascular plants, such as mosses, liverworts, and hornworts, lack these specialized cells and have simpler structures like rhizoids. They primarily rely on osmosis and diffusion for water and nutrient transportation. Vascular plants can adapt to various habitats, while nonvascular plants are commonly found in moist and shaded environments.

Step by step solution

Overview of Vascular and Nonvascular Plants

Vascular plants are a large group that includes flowering plants, conifers, ferns, and others. They have specialized cells to transport water and nutrients through the plant. Nonvascular plants are simpler plants like mosses, liverworts, and hornworts, which do not possess specialized cells for transportation.

Structural Differences

Vascular plants have well-developed roots, stems, and leaves. The main structural components of vascular plants are xylem, which helps in water transportation, and phloem, which aids in transporting nutrients and organic compounds. On the other hand, nonvascular plants have structures called rhizoids, which function like roots but are not as complex. They also lack proper stems and leaves.

Water and Nutrient Transportation

In vascular plants, there are specialized cells called xylem and phloem that help transport water, nutrients, and food throughout the plant. This allows them to grow taller and larger than nonvascular plants. In nonvascular plants, water and nutrient transportation occur through processes like osmosis and diffusion, as they do not possess specialized cells for transportation.

Examples of Vascular and Nonvascular Plants

Examples of vascular plants are numerous, as they make up the majority of plant species. Some examples include dandelions, oaks, pines, and ferns. Nonvascular plants, on the other hand, include simpler and smaller plants like mosses, liverworts, and hornworts.

Habitats

Vascular plants can be found in various habitats, from dry deserts to tropical rainforests and even aquatic environments. They can adapt to a wide range of environments due to their efficient transportation system for water and nutrients. Nonvascular plants are commonly found in moist, damp, and shaded areas, such as the forest floor or near a water source. Their lack of a proper transportation system limits them to live mostly in moist environments where water is abundant.
