1 Introduction to Plants Introduction to Plants Agenda: Handout
on non-vascular plants Vascular notes on plants in foldable Draw
and label seeds Warm Up: new handout What do you think is the
importance of plants to study and understand? Homework: None

Slide 2
KINGDOM PLANTAE THE ORGANISMS IN THIS KINGDOM ARE VARIOUS TYPES
OF PLANTS Copy on front inside cover of foldable
Slide 3
Overview of Plants: All plants are multicellular & contain
chlorophyll inside of chloroplasts All plants are multicellular,
eukaryotic organisms that reproduce sexually Many medicines are
produced by plants Plants are very diverse & may be terrestrial
or aquatic Vary in size from 1 mm in width to more than 328 feet
May live a few weeks or some over 5000 years More than 270,000
plant species identified, but new species still unidentified in
tropical rain forests

6 How Plant Adapts to Land Problems: Need minerals Need

Height for Light Adaptations for Drier environment Adaptations for
Drier environment Reproduction Reproduction Solutions: Roots absorb
H 2 O & minerals Roots absorb H 2 O & minerals Lignin &
cellulose in cell walls Lignin & cellulose in cell walls

Slide 5
5 Water Vs.Land Plant Cells Land plants have a rigid cell wall
for support Water plants cells are less rigid and rely on the water
to give them support. Roots Land plants have extensive root systems
to find water, nutrients and footing, roots are also used for
storage Water plants many do not have roots and absorb nutrients
through leaves
Slide 6
2 Major Plant Groups: Vascular & Non-Vascular Vascular
tissue: adapted to carry substances throughout the organism
Slide 7
Mosses are food for animals & help form soil & keep it
moist. Nonvascular plants:

Slide 8
NON-VASCULAR PLANTS Lack vascular tissue Use osmosis and
diffusion to transport water and nutrients Do not have true roots,
stems, & leaves. Reproduce by sperm & eggs formed at the
tip of the leafy stem. Need water source - grow on land near
streams & rivers Small and close to the ground
Slide 9
Vascular Plants Seedless ferns have spores instead of seeds
Have seeds Gymnosperms seeds with no covering Angiosperms seeds
with covering
Slide 10
Ferns are seedless vascular plants
Slide 11
21 Ferns reproduce by producing spores on structures on the
undersides of their fronds called sori. The fern plant which is the
sporophyte produces spores which germinate on free ground growing a
prothallus structure (the gametophyte) where the gametes are
produced (sperm and eggs). Because of the fact sperm must swim from
these structures ferns usually live in damp areas.
To Do! SEEDS 1. Go to back of page 2 and label SEEDS 2. Get a
plastic cup and 2 seeds. 1 sunflower seed one pumpkin seed. 3. On
pg. 2. create a detailed drawing of both seeds and put date next to
drawing 4. Wet a paper towel (not soaking wet/not dry) put seeds
into paper towel fold and put into cup. 5. Put name on cup and
place into bin 16

Tue April 15 To Do Today Check seeds - draw, label and water
Gymnosperm notes Look at gymnosperms pine cones Gymnosperm handout
Warm Up- Name a similarity and difference between a fern and a
moss. Homework: None
Slide 15
15 Seed Check examine your seeds - what can you label?
19 Seed-Producing Vascular Plants Includes two groups
Gymnosperms and Angiosperms Includes two groups Gymnosperms and
Angiosperms Gymnosperms have naked seeds in cones Gymnosperms have
naked seeds in cones Angiosperms have flowers that produce seeds to
attract pollinators and produce seeds Angiosperms have flowers that
produce seeds to attract pollinators and produce seeds
Slide 18
23 TYPES OF VASCULAR PLANTS GYMNOSPERMS: Keeps leaves all year
and has seeds in cones ANGIOSPERMS: Loses leaves once a year and
has seeds in fruit Angiosperms are divided into two groups:
Monocots and Dicots

Vascular Plants with Seeds Gymnosperms: *Keep leaves (needles)
all year *Seeds have no covering and contained in cones

Wed/Thurs April 16&17 To Do Today Check seeds - draw, label
and water Video review Plant dissetion Activity explain each answer
Warm Up- explain each answer 1. Gymnosperms have beautiful flowers
to help them reproduce. True False 2. Which of these is NOT a
gymnosperm? Cycad, Pine Tree, Ginkgo, They Are All Gymnosperms 3.
Gymnosperms have seeds. True False
