Big Idea: To be able to identify organisms in the Plant Kingdom classified into vascular and non-vascular based on specific structures.

Vascular What does it mean?

Vascular

• People: of, relating to, affecting, or consisting of a vessel or vessels, especially those that carry blood

• Plants: relating to the plant tissues (xylem and phloem) that conduct water, sap, and nutrients

Plant KingdomAll plants are included in this kingdom, which is then divided into smaller and smaller divisions based on several characteristics

Examples: • How they transport fluids • How they reproduce • Method of seed production • Type of seed leaf

 

Plants are placed in two major groups based on their internal structure. The two groups are: •Vascular plants - which have special cells to transport food and water •Nonvascular plants -which do not have the same structures for transport

Vascular vs Nonvascular

Vascular Plants

This is the largest group in the Plant Kingdom.

These plants have a well-developed system for transporting water and food • True roots • True stems • True leaves • Vascular bundles

Vascular StructuresVascular plants have tube-like structures that provide support and help transport water and food throughout the plant.

• Xylem tissue transport water and minerals from the roots to the rest of the plant.

• Phloem tissue transport food from the leaves to the rest of the plant. (sugar)

Pink = Xylem

Green = Phloem

What is the name of this vascular plant?

Types of vascular plantsExamples: • Trees and shrubs have woody stems that grow tall • Grasses, dandelions, and tomato plants have soft herbaceous stems and remain close to the ground

Nonvascular PlantsThese plants do not have a well-developed system for transporting water and food • No true roots, stems, or leaves

They get nutrients direct from environment and pass them cell to cell. This keeps these plants very small in size. Examples: •Mosses, liverworts, hornworts.

 

Vascular vs Nonvascular Key Concepts

• Minerals are natural substances that all plants need to grow.

• Vascular plants have special tissues called xylem and phloem that form tube-like pathways so that water, minerals, and food can move through plants.

• Nonvascular plants do not have these special tissues. In nonvascular plants, materials must travel from one cell to the next cell.
