2. Happy Monday! Bellwork: February 17 Copy the 2 sentences and underline key words
The concept of gene flow is demonstrated when a cow is driven off from its herd, joins another herd, and reproduces. When the cow contributes to the gene pool of the new herd, which of these most likely increases?
Natural selection
Genetic variation
Environmental fitness
Reproductive mutations

3. CO: I will describe the interactions between systems in plants
CO: I will describe the interactions between systems in plants. I will describe the reproductive parts of a plant. LO: I will write notes. I will discuss plants with a partner. I will read about plant reproductive organs.

4. Science Fact of the Day: Fingernails grow four times as fast as toenails.

5. Anticipation Guide: Decide if the following statements are true or false with your partner
Some plants are single celled organisms
Plants are prokaryotic and animals are eukaryotic
Plants are photosynthetic autotrophs
Plants have chitin in their cell walls
Pollination is a part of plant reproduction
There are carnivorous plants

6. What makes a plant a plant?
Plants
What makes a plant a plant?
Plants are eukaryotic
Plants have cell walls made of cellulose
Plants make their own energy through photosynthesis
Plants are multicellular

7. What plants need to survive…
1. Sunlight
2. Water
3. CO2 & Oxygen
4. Nutrient and water movement

8. Plant Parts/Systems
Reproductive System = Flower (with male and female parts)
Transport System = tissues in stem
Nutrient System = Leaf + Root
Structural Support System = Stem + Roots
All of these parts and systems work together to help a plant maintain homeostasis.

9. Think-Pair-Share How do the leaves, stem, and roots work together to help a plant maintain homeostasis?

10. Is It a Stem, Leaf, Root, Flower, Fruit or Seed?
Fruit/Vegetable
Part of Plant
Broccoli
Cabbage
Carrot
Celery Stalk
Corn Kernel
Garlic
Onion
Potato
Tomato
Zucchini

11. Plant Reproductive Structure
Tomorrow you will be dissecting a flower, identifying the parts, and discussing how plants interact with their environment.
So let’s take a few minutes to talk about the structure of flowers…

12. Flower Parts Complete flowers have four parts.
Stamen – male part, include anther and filament
Anther: produces pollen
Pollen: plant “sperm”, fertilizes eggs
Carpel (pistil) –female part, includes stigma, style and ovary
- Ovary: organ that holds egg, where fertilization occurs
Sepals – protection for flower during development
Petals – protection for flower as well as attracting pollinators

13. Today’s assignment
Read the article on plant structure and reproduction. Highlight or underline the key words.
Complete the questions.
Color the flower according to the directions.
Label each flower part (ex. A=anther)
This is a grade due at the end of class.
