5. I. Seedless Nonvascular Plants (Bryophytes):
- lack tissue to move water and sap
throughout the plant
- small, short plants that most live in
moist environment
(mosses, liverworts, hornworts)
Types of plants

6. II. Vascular Plants (3 Subdivisions):
1. Seedless Vascular (ferns, horsetails,
clubmosses)
- sperm travels in water to reach egg
2. Two Seed Bearing Vascular
-Gymnosperms (Naked Seeds)
(Conifers, cycads, ginkos)
- Male cones release pollen in the spring, which is
spread by the wind
- Female cones release sticky fluid to capture pollen
- Overtime, pollen burrows into female cone’s ovule to
reach & fertilize egg
- Eventually cone falls and turns into conifer tree
Types of plants (cont’d)

7. GymnospermReproduction
Gymnosperms have both male and female
cones
Male cones – usually found at
the highest parts of the tree.
Contain pollen that is carried by
wind to female cones
Female cones – usually found
lower on the tree than male cones.
Will open to take in pollen then
close tightly for germination, then
open again to release the seeds

8. -Angiosperms (Flowering plants, grasses,
deciduous trees)
- Angiosperms are seperated into 2 categories
Monocotyledons (seeds which create 1 leaf when
sprouting & Dicotyledons (seeds which create 2
leaves when sprouting)
- Flower grows to attract pollinators & house
the ovule with eggs inside as well as holding
sperm that will release pollen
- Once eggs are fertilized the ovule becomes
fruit which protects the seeds
Types of plants (cont’d)

9. Flowering Plants
Two different Types:
Monocots and Dicots
1. Monocot Characteristics
Single Cotyledon – a seed that
creates a single leaf at sprouting
Leaves with parallel veins
Flower parts in multiples of three (3)
Vascular tissue throughout the stem
Fiberous root system
Monocots are usually “grassy” plants
Examples : Corn, Bamboo,
Sugar Cane, and grass.

10. 2. Dicot Characteristics
Two cotyledons
Leaves with branched veins
Flower parts in multiples of four (4)
or five (5)
Vascular tissue in a ring in the stem
Tap root systems
Dicots are usually non-grassy
with branching stems which may
be woody
Examples : Most trees, roses,
daisies,

11. Comparative Characteristics.

12. What are fruits?
In botany, a fruit is the seed-bearing structure in
flowering plants (also known as angiosperms) formed from
the ovary after flowering. Fruits are the means by which
angiosperms disseminate seeds. Edible fruits, in particular,
have propagated with the movements of humans and
animals in a symbiotic relationship as a means for
seed dispersal and nutrition; in fact, humans and many
animals have become dependent on fruits as a source of food

13. Epiphytes and Legumes
*An epiphyte is a plant that grows harmlessly
upon another plant (such as a tree) and derives
its moisture and nutrients from the air, rain,
and sometimes from debris accumulating
around it. Epiphytes differ from parasites in
that epiphytes grow on other plants for
physical support and do not necessarily
negatively affect the host.
*Legumes are plants that bear their
fruit in pods, which are casings with
two halves, or hinges. Legumes are a
very healthy food because it is low in
fat and high in protein. Legumes are
also very high in fiber and other
nutrients.

14. Plant Type Questions
1. What is a gymnosperm? Angiosperm?
2. Define Xylem and Phloem.
3. Differentiate nonvascular and vascular
plant.
4. Why most nonvascular plants live so close
to water?

16. Roots, Stems, and Leaves
Seed plants generally have three structures
Roots - a system for
absorbing dissolved
nutrients and water,
and anchoring.
Stems - a structure used to
support the body of
the plant, and store
sugar.
Leaves - the main
photosynthetic region
of the plant.

17. How does a plant get water and
nutrients around in the plant?
Xylem Tissue - cells that
make hollow tubes
that are water-proof
and allow water to
rise in a plant
(capillary action)
Phloem Tissue- cells that
form tubes that allow
foods and minerals
to move in the plant

18. Xylem Phloem

19. How do plants grow?
Meristematic Tissue - tissue that
allows the plant to grow
up, down, or out.
Apical Meristem
- the meristematic tissue that
allows growth at the tips of the
root and the tips of the branch
Vascular Cambium
-meristematic tissue in the
outer layer of the stem/trunk
that allows growth outward
(thicker)
Root
tip
Bundles in a non-woody
plant

20. ALTERNATION OF GENERATION
A plant alternates between a diploid stage (asexual) and a
haploid stage (double fertilization)

21. Angiosperm Flower Parts
(Complete flower)
Complete flowers have four
parts.
1. Stamen – male part
anther and filament
2. Carpel (pistil) –female part
stigma, style and ovary
4. Petals – protection for flower
as well as attracting
pollinators
3. Sepals – protection for
flower during development

22. 1. When a pollen
grain reaches the
stigma, it sticks
and begins to
makes its way
down the Style.
Creation of a seed
2. As the pollen
continues down
the style makes its
way to the ovary.
3. When it
reaches the
Ovule, it fertilizes
the eggs.
