The Kingdom Plantae
This kingdom is composed of
multicellular, eukaryotic autotrophes.
Kingdom Plantae
The Producers
Plants are the
chief producers in
all ecosystems.
Virtually all food
webs rely on
plants ability to
convert energy
(sunlight) into
matter
(carbohydrates)
2 Phyla
There are 2 phyla in the kingdom
plantae.
The first are the bryophytes.
Bryophytes are plants that lack
true leaves and stems.
Bryophytes cannot grow tall
because they do not contain
vascular tissue.
Vascular tissue
Vascular tissue acts as a transport
system in some plants.
The two types are called Xylem
and Phloem.
Xylem transports water from the
roots to the rest of the plant.
Phloem transports nutrients from
the leaves to the rest of the plant.
Bryophytes
Bryophytes do not grow flowers or
fruit, nor do they produce seeds.
They cannot grow tall, all cover
the ground and trees like a carpet.
They alternate between sexual and
asexual reproduction.
Bryophytes are only found in moist
environments.
Types of bryophytes.
Mosses
These are small,
soft plants that
tend to grow in
clumps in shady
areas with a lot of
moisture.
Types of bryophytes
Liverworts and
hornworts
It is estimated
that there are
6000 to 8000
species of
liverworts
Tend to have
simpler structures
than mosses.
The first plant?
Bryophytes!
Tracheophytes
More complex than
bryophytes.
Are capable of growing very
tall.
Some trees are over 350 feet
tall.
3 classes
Ferns
Gymnosperms
Angiosperms
Ferns
The most similar to
bryophytes.
Like the bryophytes ferns
reproduce with an alteration
of generations.
Only found in moist areas.
Leaves are called fronds.
Can grow as big as trees in
the tropics.
Fern-coal connection
Ferns were once the dominant
form of plant life on earth.
Coal comes from fossilized fern
forests.
The Gymnosperms
Produce seeds that are
stored within cones.
Often referred to as conifers,
most know then as
evergreens or pines.
Have specialized leaves
which resemble needles.
Gymnosperms
Gymnosperms are
always losing and
growing new needles,
but are never completely
bare.
Adapted to cold
climates. (needles and
resin)
Important commercially
for lumber and paper.
Angiosperms
Angiosperm means
“hidden seeds”.
Seeds produced by
angiosperms are
covered by a fruiting
body.
Angiosperms also
produce flowers.
Angiosperms and animals.
Angiosperms produce fruit as a
mean of seed dispersal.
Animals eat the fruit and then
scatter the seeds in their wastes.
Angiosperms also produce
flowers.
Angiosperms
All flowering and fruiting
plants are angiosperms.
Most angiosperm trees
lose their leaves
seasonally.
Two types of
angiosperms, monocots
and dicots.
Tracheophytes!!
