What were some things you learned from the Plant Reading Guide?
What makes plants different from other organisms?
What are some differences?
Vascular Plants vs. Nonvascular PlantsVascular Plants vs. Nonvascular Plants
Vascular Plants have tubes (xylem and phloem) to carry water & nutrients to all parts of the plant.
Ex. Grass, Trees, etc.
Nonvascular Plants grow low to the ground absorb moisture
& nutrients through osmosis & diffusion
Ex. mosses
Vascular Plants vs. Nonvascular PlantsVascular Plants vs. Nonvascular Plants
Which areas of the world would best support Non-vascular plants?
•Rainforest?
•Desert?
•SD in a drought year?
Roots Functions…
Absorbing water
Store Food (vegetables: potatoes, carrots, etc)
Anchor the plant
Site for *Nitrogen Fixation
Types…
Taproot – example: carrot
Fibrous root
Roots Nitrogen Fixation converts N gas in the air into a usable form.
Performed by bacteria
that live on the roots of
plants called LEGUMES,
such as alfalfa and soybeans
**Not possible if roots didn’t
provide a home for bacteria
Roots, continuedRoots, continued
Leaves Functions…
Collect sunlight to carry
out Photosynthesis
– using light to make
chemical energy (glucose)
Leaves Function
Regulate gas exchange and *water loss in the Stomata (openings in the underside of leaves)
*Transpiration is
Plant perspiration
Stems
Functions…
Support
Transport of nutrients
Phloem – carries food from the leaves to the roots (moves
down)
Xylem – carries water from the roots to the leaves (moves
up)
Some photosynthesis
Stems
PHLOEM = PHOOD
XYLEM = WATER (x is close to w in alphabet)
Flowers Function
Reproduction
Skill Checks for Plant UnitMonday, Sept. 16 Plant Structures and Functions Friday, Sept. 20 Flower Structure and Function Wednesday, Sept. 25 Plant Unit Test and Edible Plant Potluck!!!
*Edible Plant Day Wednesday, September 25!! Each person will be responsible for bringing in a plant “sample” to share with the rest of the class. You will need to do a little research on plant and tell us some interesting facts about it, as well as where it grows, how it is pollinated, and also talk about the nutritional benefits of eating this plant.
Plant is Like…..Step 1: Create a Smoosh Booklet—make sure you
have “crisp” folds!Step 2: Create a Title Page “A Plant is Like” by
“you”Step 3: For each page in your booklet, you will
need to create an analogy for each of the following plant parts and then write the function of that plant part. You must also draw a simple illustration for this analogy.
Booklet is worth 8 points and you must have a title page, analogy for each plant part, and illustration.
EXAMPLEA Root is Like…..A Sponge
Because roots ABSORB WATER, store nutrients, and anchor the plant, assist with Nitrogen fixation
Roots—Absorb water, anchor the plant, store nutrients, assist with Nitrogen fixation
Stems—transport water and food and help support the plant
Leaves—collect sunlight to carry out photosynthesis to make “food” for the plant
Flower—attracts pollinators to allow for reproduction
Stomata—regulate transpiration (water loss) and gas exchange
Xylem—vascular tissue that transports water (up from roots)
Phloem—vascular tissue that transports food (down from leaves)
Flowers Functions…
Reproduction
Pollen (Plant Sperm) - An adaptation that allows plants to reproduce sexually while remaining stationary
Style--pollen travels down it to reach ovary
Stigma-collects pollen..it’s sticky!
Pistil=Female parts
Ovary contains Ovules (eggs) that become seeds when fertilized
Anther—produces pollen
Filament—holds up anther
Stamen=male parts
PollinationPollination
Self pollination – plant pollinates itself
Cross pollination – plant pollinates another plant
Insect pollination – colorful fragrant flower
Wind pollination – wind carries pollen
to another plant (ah-choo!)
Seeds (plant babies) – The product of
Successful pollination
Sexual Encounters of the Floral Kind…..
In your notes, list at least 3 different pollination methods of plants in this video clip.
Explain how the African Hammer Orchid gets pollinated.
How did the Trigger plant get its name?
Let’s Review
Edible Plant PotluckWednesday, September 25!!
Tomorrow will be our research day, so have several plants in mind that you would like to bring for the potluck.
COMMUNICATE with the person/people that buy the food in your home—put what you need on a grocery list. DO NOT leave this until Monday night!!!
PLANT TESTWednesday, September 25
What should you study?Notes on Non-vascular and Vascular PlantsPlant Structures and FunctionsFlower Structures and FunctionsSkill Checks!Go to our class website (linked to Infinite
Campus) to access the notes and a review vodcast!-
Seed DispersalSeed DispersalPrickly hooks – carried by organisms on their fur
Wings (helicopter seeds) – carried by the wind
Fruit covered seeds – carried by the organism that ate the fruit, eventually the seed is dropped onto the ground along with some great natural
fertilizer
Seedy Side of PlantsIn your notes, describe how each of these of
these plants get their seeds dispersed.
