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

4. Anticipation Guide: Decide if the following statements are true or false with your partner 1.Some plants are single celled organisms 2.Plants are prokaryotic and animals are eukaryotic 3.Plants are photosynthetic autotrophs 4.Plants have chitin in their cell walls 5.Pollination is a part of plant reproduction 6.There are carnivorous plants TRUE TRUE TRUE FALSE FALSE FALSE

5. 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

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

7. 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.

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

9. Is It a Stem, Leaf, Root, Flower, Fruit or Seed? Fruit/VegetablePart of Plant Broccoli Cabbage Carrot Celery Stalk Corn Kernel Garlic Onion Potato Tomato Zucchini flower leaf root stem seed root fruit

10. 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…

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

12. Today and tomorrow…
