What is a Plant?
• I. The Plant Kingdom
A. Autotrophic- Make their own food through
Photosynthesis
B. Multi-cellular- complex cells organized into
tissues to transport materials.
What is a Plant
C. Cells1. Nucleus (eukaryote).
2. Chloroplasts- where food is made.
3. Vacuole- storage sac for water, waste,
or food.

D. Adaptations for Living on Land
1. Obtaining Water
2.Retaining Water-cuticle covering the leaves
3.Transporting Materials- through vascular
tissue
4.Support
5.Reproduction- Sexual
E. Classification of Plants1. Nonvascular- lack a well-developed
system of tubes for transporting water
and materials. (No roots, thin cell
walls, short)
E. Classification of Plants2. Vascular- Well developed tubes to
transport food, water, waste (Strong,
stable, tall)
F.
Origins of Plants
1. 400 Million Years old.
2. Chlorophyll- Green Pigment found in the
chloroplasts of plants, algae and some
bacteria.
G. Life Cycle p. 111
1. Sporophyte stage- plant produces spores that
develop into new organisms.
2. Gametophyte stage- the plant produces two
kinds of sex cells (sperm and egg).
Sporophyte and Gametophyte
II. Photosynthesis and Light
A.
Light
1. Transmission- light passes through
2. Reflection- Light bounces back
3. Absorption- Objects take in light.
4. When light strikes a green plant, most of the
green is reflected, all other colors are absorbed.
5. Plant Pigment- chlorophyll absorbs light (reflects
green)
B. Photosynthesis Process
1. Capturing Energy-Chlorophyll traps
light to make sugar an oxygen from
carbon dioxide and water. Pg. 118

B. Photosynthesis Process
2.Photosynthesis Equation
Carbon Dioxide + Water  Sugar + Oxygen
(CO2) +
(H20) (C6H12O6) + (O2)

Fairy Tales and Nursery Rhymes
• Today we are celebrating the unique
differences between Mosses, Liverworts, and
Ferns
• Objective: Students will use their
understanding of Non-Vascular plants to write
and perform a nursery rhyme explaining each
unique characteristic.
Fairy Tales and Nursery Rhymes
• Preparation: 10 minutes
• Activity:
1. All Non-Vascular plants have a similar
transport system for food, water, and waste.
2.Using your Plant Notes chart from yesterday, I
will assign you one of the three Non-Vascular
plants.
3.Choose a nursery rhyme and write the REAL
words
Fairy Tales and Nursery Rhymes
4.To help the class in reviewing the unique
characteristics of your Non-Vascular plant,
change the words of your nursery rhyme to
words that describe your plant. (Use your
journal)
5. Practice, Practice, and get ready to present
your plant rhyme to the class.
Nursery Rhyme Idea
I'm a piece of algae in the ocean I sway.
Where are my roots, stems, or leaves NOT
TODAY!
When I live in water asexual I stay.
Red, Green, and Brown on any given day!
