Transcript Plant Groups Vascular and Non Vascular

Plant Kingdom
All 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
Vascular vs Nonvascular
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 Plants
This is the largest group in
the Plant Kingdom.
These plants have a welldeveloped system for
transporting water and
food
• True roots
• True stems
• True leaves
• Vascular bundles
Vascular 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)

What is the name of this vascular plant?
Types of vascular plants
Examples:
• 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 Plants
These plants do not have a welldeveloped 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.
