Vascular Plants
What are
vascular
plants?
• The largest group in the Plant
Kingdom.
• Have a well-developed system for
transporting water and food; so,
they have roots, stems, and leaves.
• Vascular plants have tube-like
structures that provide support and
help circulate water and food
throughout the plant.
Vascular Plants
What are
vascular
plants?
• Xylem transport water and minerals
from the roots to the leaves.
• Phloem transport food from the
leaves to the rest of the plant.
• Ex: Trees and shrubs with woody
stems (hard/brown) that grow
very tall and grasses, dandelions,
and tomato plants with soft
herbaceous (green) stems.
Nonvascular Plants
What are
• They DO NOT have a wellnonvascular developed system for transporting
plants?
water and food; they DO NOT
have true roots, stems, or leaves.
• Get nutrients directly from the
environment and distribute it from
cell to cell. This results in very
small plants.
• Examples include mosses,
liverworts, and hornworts.
Spanish Moss
Seed-Producing Plant
• Reproduce through seeds they make.
• Seeds contain the plant embryo (the beginnings of
roots, stems, and leaves) and stored food
(cotyledons) and are surrounded by a seed coat..

Seed Coat
• There are two major groups of seed-producing
plants: flowering plants and cone-bearing plants.
Spore-Producing Plant
•
•
•
•
Produce spores for reproduction instead of seeds.
Spores are much smaller than seeds (look like dust).
Almost all flowerless plants produce with spores.
Examples include mosses and ferns.
Ferns
Mosses
Flowering Plants
• Flowering plants differ from conifers because they
grow their seeds inside an ovary, which is embedded
in a flower.
• Flowers then becomes a fruit containing the seeds.
• Examples include most trees, shrubs, vines, flowers,
fruits, vegetables, and legumes.
Cone-Bearing Plants
• Most cone-bearing plants are evergreen with needlelike leaves.
• Conifers never have flowers but produce seeds in
cones.
• Examples include pine, spruce, juniper, redwood,
and cedar trees.
Monocot Plants
• A seed with one food storage area.
• Flowers have 3 petals or multiples of 3.
• The leaves of monocots are long and slender with
veins that are parallel to each other.
• Examples include grass, corn, rice, lilies, and tulips.
Dicot Plants
• A seed with two food storage areas.
• Flowers of dicots have either 4 or 5 petals or
multiples of these numbers.
• Leaves are usually wide with branching veins.
• Examples include roses, dandelions, maple, and oak
trees.
