Plants
Two Groups of Plants
 Nonvascular - most primitive, rely on
water coming to them.
 Vascular - contain vascular tissue that
transports water.
 And Fungi – which are not plants
Vascular Plants
 Have vascular tissue –
tissue that moves food
and nutrients around
plant
 Xylem and phloem
 Leaves, stems, and roots
 Produces food for plant
in leaves




May have a long life span –
one season or many
grows tall and wide
Has chlorophyll for photosynthesis


examples: ferns, trees,
grasses and flowering
plants
Non-vascular Plant
 Nonvascular
 no vascular tissue
 no leaves, stems,
or roots
 low growing, close
to the ground
 reach maturity
quickly
 can grow in
varying climates
 Produce food in
every cell
Mosses
 a flowerless plant
 lies flat and grows in moist areas
(carpet like appearance)
 reproduces sexually
 Economics - used by gardeners as a
mulch because it helps keep moisture
close to the plants roots.
And Non Plants
Fungi  most primitive; do not have
true roots, leaves,
stems
 do not contain chlorophyll in their
cells
 Obtain their food from other sources
– heterotrophs or parasites
 Reproduce asexually - spores
 Example:
 Mushrooms, molds, puffballs,
lichens
Mushrooms and Toadstools
Found in damp, shady places
Very short lifespan
Most are poisonous
(if it is red it is poison)
Some grown for commercial
use
Lichens
 fungi which grow in symbiosis with algae,
forming a structure in which the algal cells
are imbedded in the fungal structure
(hyphae)
 the algae gets water and minerals from the
fungus
 the fungus gets food from the algae which
is able to conduct photosynthesis
 found on bare rocks in a crust like, shrub
like, or leaf like form
 can be used to make perfume or for dyes
Two Groups of Vascular Plants
 Gymnosperms - naked seed
 Angiosperms - vessel seed
Gymnosperm vs. Angiosperm
 Gymnosperm  expose their seeds
 examples-pine, spruce, ferns
and conifers trees
Angiosperm
produce and store their
seeds in an ovary – often
called fruit
examples - roses, elm
trees, geraniums, apple
trees, etc.
Subclasses of Angiosperms
A. Monocots –
 single seed leaf
(cotyledon)
 flowers/petals grow in
groups of three
 leaves have parallel
veins
 Flowers often small, overlooked
 Usually grow for only one year
 Examples: corn, grasses, onions,
lilies and many grains
Dicots
 two seed leaves (cotyledons)
 flowers/petals grow in groups
of four or five
 leaves have network veins
that branch out
Greatest number of plants are
dicots
Tend to live a long time – one
season or many
Produce food, clothing,
housing
Examples: trees, sunflower,
beans, pumpkins and clover.
