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.

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

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

What plants need to survive…

1. Sunlight

2. Water

3. CO2 & Oxygen

4. Nutrient and water movement


Plant parts systems

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.

Think-Pair-ShareHow do the leaves, stem, and roots work together to help a plant maintain homeostasis?

Plant reproductive structure

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…

Flower Parts

Complete flowers have four 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

Sepals– protection for flower during development

Petals– protection for flower, as well as attracting pollinators


Today and tomorrow

Today and tomorrow…

  • Read the article on plant structure and reproduction. Highlightor underline the key words.

  • Answer the questions.

  • Color the flower according to the directions.

  • We will finish this tomorrow – it is for a GRADE!
