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.
