All plants…
• Eukaryotic & multicellular• Are producers – an organism that makes its
own food by using an outside energy source (the sun)
• Have cell walls (organelle only in plants)
• Have chloroplasts (organelle only in plants)
What is a cell wall?• Provides support and protection• Made of cellulose and lignin
Organelle that converts light energy to chemical energy through a process called photosynthesis
(we’ll talk about that later)
What is a chloroplast?
Lets create a classification map (tree map)
How can plants be classified?
Classification of plants
plants
vascular Non-vascular
Contains specialized tubes that transport
water & nutrients
Does not contain vascular tissue
plants
vascular non-vascular
Contains specialized tubes that transport
water & nutrients
Does not contain vascular tissue
Seedless
•Reproduces by spores (needs water)•No flowers•No roots (have rhizoids)•No cuticle•Small in size•Examples: liverworts, mosses, hornworts, bryophytes
Non-Vascular Seedless Plants
• Rhizoids helps to anchor plant
• Gets water and nutrients by osmosis and diffusion

Hornworts
Mosses
Bryophytes
plants
vascular non-vascular
Contains specialized tubes that transport
water & nutrients
Does not contain vascular tissue
Seedless
•Reproduces by spores (needs water)•No flowers•No roots (have rhizoids)•No cuticle•Small in size•Examples: liverworts, mosses, hornworts, bryophytes
Seed Seedless
•Larger than nonvascular seedless plants•Examples include: ferns, clubmoss and horsetails
Vascular Seedless Plants
• Contain vascular tissue in root, stem and leaves.
• Vascular tissue is tube structures that transport water and nutrients.
• Examples include Tree ferns, club moss and horsetail.

Angiosperms Gymnosperms
•Cone-baring seeds•Example – pine, cedar, spruce
Gymnosperm Plants
Pine Tree Cedar Tree Spruce Tree
Gymnosperms
• Seeds produced in a cone• Group includes oldest plant and tallest plant.
Bristlecone Pine - Know to live for over 5,000 years. Coast Redwood - Forest trees grow over 379 feet tall

Angiosperms Gymnosperms
•Cone-baring seeds•Example – pine, cedar, spruce
•Flowering seeds•260,000 types•Many foods and other items•Seeds as part of a fruit•Fruit grows from flowers
Apple Tree
SunflowerLady Slipper Orchid
Pumpkins
Angiosperms
• Grow in a variety of habitats• Most food eaten by humans comes from
angiosperms or animals that eat angiosperms.• Other items such as clothing, medicine,
building materials.• Flowering plants

Leaf •major site of photosynthesis•Captures light energy and converts to chemical energy to provide food.

Parts of a plant
roots
Stem•Connects the roots to the leaves•Supports branches and leaves•Transports (moves) water, minerals and food.

Parts of a plant
Roots
•Vital•Anchors•Keeps plant upright•Absorbs water•Stores food (sugar) – ex: radishes, carrots, potatoes, etc.•Absorbs minerals from the soil

Flower•Attract insects to help the plant reproduce.•Part of the plant that has the reproductive organs
Parts of a plant

leaf
Cuticle• Waxy protective layer on leaves, stem and flowers• Provides protection from insects• Slows evaporation of water
Parts of a Flower
StamenMale part of flower, produces pollen
PetalColorful part that attracts pollinators
SepalProtects the flower before it opens
PistilThe female part of the plant
AntherProduces and carries pollen
FilamentFine hair like stalk the anther sits on
StigmaSticky bulb that receives the pollen grains
StyleLong stalk that the stigma sits on
OvaryHas seeds inside
OvuleThe part of the ovary that becomes the seed
Parts of a flower
Photosynthesis• A series of chemical reactions that convert
light energy, water and carbon dioxide into the food-energy molecule glucose and give off oxygen.
• Occurs in the chloroplasts• Chloroplasts contain the pigment chlorophyll,
a chemical that absorbs and reflects light.• Leaves appear green because the chlorophyll
reflects green light and absorbs all the other colors of light.
Photosynthesis
• C=Carbon• O=oxygen• H=hydrogen• CO₂ = carbon dioxide• H₂O = water• C₆H₁₂O₆ = sugar/glucose
6CO₂ + 6H₂O
C₆H₁₂O₆ + 6O₂Light energy
Chlorophyll
Cellular Respiration• All organisms require energy (usable power)
to survive.• Energy is in the chemical bonds in food
molecules.• Cellular respiration is a series of chemical
reactions that convert the energy in food molecules into a useable form of energy called ATP.
• ATP= (adenosine triphosphate) • ATP is the energy used for all cellular
processes (everything the every cell does) • Example: muscle contraction uses 2 million
ATP molecules per second. Without ATP we would die.
Cellular Respiration
Cellular Respiration takes place in the mitochondrion of the cells in ALL living things.
C₆H₁₂O₆ + 6O₂ 6CO₂ + 6H₂O + ATP (glucose)

• Cut and glue picture on right side under notes.• Draw arrows on picture to match website
address image for the direction of CO2, H2O and O2.
• Color carbon dioxide circles orange, oxygen red circles and water blue circles (on picture and legend)

What are mangroves?
Mangroves are various kinds of trees and shrubs that grow in saltwater habitats in the tropics
and subtropics.
Location of Mangroves around the world
Mangroves
Activity• Cut out Mangrove article and paste on
right side of notebook• Number paragraphs• Circle at 4-6 vocabulary words per
paragraph (pick one color)• Read article, underline any important
information (another color - no more than 8 words per underline)
• On the left side of the INB (use different color for each)• Make a boarder with all the vocabulary words you circled in the
article• In the top ¼ of the page - create a title• Next ¼ draw a picture to represent what you read• Pick most important vocabulary words and make a mini boarder
around your picture.• Choose the most important quote from the words that your
underlined and rewrite it in the next ¼• In the last ¼ of the page, create 1 (or more) higher order
thinking question based on the reading…and….• Answer the HOT question
Create a “1 – Pager”

• Take 3 sticky notes and write your name on them.
• Visit 3 other notebooks and look at their 1-pager
• Leave your sticky notes on the pages you view
