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
Plant Kingdom
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
Ways to remember!

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.
