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 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 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, 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 Unit Monday, 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.

EXAMPLE A 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

Pollination 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 Potluck Wednesday, 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 TEST Wednesday, September 25 What should you study? Notes on Non-vascular and Vascular Plants Plant Structures and Functions Flower Structures and Functions Skill Checks! Go to our class website (linked to Infinite Campus) to access the notes and a review vodcast!-class website

Seed Dispersal Prickly 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 Plants In your notes, describe how each of these of these plants get their seeds dispersed. 1. Quinine 2. Acorn 3. Cashews 4. Fig
