Transcript Plant Classification

Plant Classification
5.5.3 Distinguish between the following phyla of plants,
using simple external recognition features: bryophyta,
filicinophyta, coniferophyta, and angiospermophyta
1) Bryophyta
• Mosses, hornworts, and liverworts
•
plants
o Do not have
(vascular transport tissue for moving water and
sugars)
o Lack
o Small plants that must live in damp environments
o Do not produce flowers or seeds

Mosses
Liverwort
Hornwort
5.5.3 Distinguish between the following phyla of plants,
using simple external recognition features: bryophyta,
filicinophyta, coniferophyta, and angiospermophyta
2) Filicinophyta
•
•
plants – have vascular tissue
(xylem and phloem) to conduct water and sugars
oHave true roots, stems and leaves
• Do not produce flowers, pollen or seeds
oReproduce by producing
oSperm
eggs and fertilize
 Ferns usually grow in places with
oZygote grows into
Ferns
frond
fiddlehead
This is the sporophyte (fern) which
produces spores that grow into a
gametophyte.
This is the gametophyte,
called a prothallus, which
produces egg and sperm
Sperm fertilizes egg to
create zygote that grows
into the sporophyte (fern)
5.5.3 Distinguish between the following phyla of plants,
using simple external recognition features: bryophyta,
filicinophyta, coniferophyta, and angiospermophyta
3) Coniferophyta
•
plants that produce
• Cone-bearing trees like
• Usually
with
o Evergreen means it retains some leaves all year long
• Produce male and female cones
o Male cones produce
(contains sperm)
o Wind often blows pollen to female cone
o Eggs are
Conifers
Female
Male

4) Angiospermophyta
•
Plants that produce
• Predominant form of plant-life today
• Produce
• After eggs are fertilized,
o Two groups:
 Monocotyledonae (
 Dicotyledonae (
)
)
Angiosperms – Flowering Plants
