Appointment Clock 12:00 3:00 6:00 9:00

12:00 With your 1st Partner: 1. Cut out the phylogenetic Tree 2. Cut out the plants and place them at the top in order of evolution 3. Use the word bank to complete the chart Chapter 29-30

Place each picture/word in the correct location on the phylogenetic tree 1 Conifers Ferns Flowering Plants Mosses Angiosperm Bryophytes Gymnosperm Pteridophytes (Tracheophytes) Flowers/Fruit Non-Vascular Land plants Pollen/Naked seeds Seedless vascular plants Ancestor Green algae Non-Vascular Plants Seed Plants Seedless Plants Vascular Plants Chapter 29-30

3:00 With your 2nd Partner: 1. Cut and glue down the flower diagram 2. Label everything you can 3. Distinguish between male and female parts 4. List the pollination process (starting with a bee - ending with the complete fertilization causing the formation of the endosperm and zygote With your 2nd Partner: 1. Cut and glue down the flower diagram 2. Label everything you can 3. Distinguish between male and female parts 4. List the pollination process (starting with a bee - ending with the complete fertilization causing the formation of the endosperm and zygote Chapter 38 Word Bank: Anther Ovary Style Carpel Pollen Egg Stamen Filament Stigma Word Bank: Anther Ovary Style Carpel Pollen Egg Stamen Filament Stigma

Answer Style Filament Stamen Pollination: A bee picks up a pollen grain from the anther, then lands on the sticky, nectar-laced stigma of the carpel transferring the pollen grain and beginning the process of double fertilization (see next slide) Chapter 38

Fertilization in flowering plants Double fertilization 2 sperm from pollen grain 1st sperm makes the pollen tube, then fuses with 2 polar nuclei = endosperm = 3n, Triploid endosperm = food tissue for the new seedling 2nd sperm gets to fertilize the egg = zygote = 2n, diploid Chapter 38

6:00 With your 3rd Partner: 1. Cut and glue down the leaf cross section 2. Label # Detail Transpiration - Write about the leaf anatomy involved Write about the vascular tissue, Write about the forces driving it Chapter 35 Word Bank: Cuticle Epidermis (upper/lower) Guard Cells Mesophyll Layers (Palisades/Spongy) Phloem Stomata Xylem Word Bank: Cuticle Epidermis (upper/lower) Guard Cells Mesophyll Layers (Palisades/Spongy) Phloem Stomata Xylem

Guard Cells regulates opening of stoma to increase or decrease transpiration Stoma pores (more numerous on the bottom of most leaves) for exchange of CO 2, O 2 & water in transpiration Palisade Layer Mesophyll/Spongy Layer area for gas & water exchange Upper Epidermis Cuticle Lower Epidermis Xylem vascular tissue, transpiration pull moves water & mineral from roots to shoots to leaves Phloem Leaf Anatomy associated with Transpiration Chapter 35-36

Transpiration: Movement of water through a plant and eventual evaporation from leaves (but also stems & flowers) Sclerenchyma Cells (dead at functional maturity) water-conducting cells of xylem tracheids vessel elements Xylem - Vascular tissue that moves Water & Minerals Up (from Roots to Shoots to Leaves) Vascular Tissue associated with Transpiration Chapter 35-36

Forces associated with Transpiration Bulk flow - movement of fluid driven by pressure Starts with Root pressure from high water potential to low (soil = -0.3 to root hairs = - 0.6) apoplast - water movement through cell wall symplast - water movement through plasmodesmata - junctions connecting cytosol of neighboring cells Casparian Strip - a water proof band of cell wall material along the endoderm of roots that serves to assist the flow of water and minerals into the xylem Then moving water from roots = -0.6 to shoots = to leaves = -1.0 through the Xylem by way of: Cohesion - hydrogen bonding btw water molecules, makes them “cling” together And Adhesion - adhering to the cell wall Leaf Transpiration (most important factor in movement of water up a tree) causes negative pressure pulling water upward by way of tracheids and vessel elements in the xylem If the molar concentration of mineral solution in the soil is said to be 0.2 Molar. Calculate the solute potential at 21˚C.  S = - iCRT = - (2) (0.2M) ( Liters/Mole) (294) = bars Relate and Apply – Think of sucking on a straw – you create A negative pressure, driving the liquid from the cup to your mouth

9:00 With your 4th Partner: 1. Referring to the leaf cross section 2. Detail Photosynthesis - Write about the leaf anatomy involved Write about the organelle involved Sketch and label the Light Dependent and Light Independent Reactions Chapter 35

Guard Cells regulates opening of stoma to regulate exchange of CO 2 and O Stoma pores (more numerous on the bottom of most leaves) for exchange of CO 2, O 2 & water in transpiration Palisade Layer column-shaped cells with a high concentration of chloroplast for photosynthesis Mesophyll/Spongy Layer area for gas & water exchange Upper Epidermis Cuticle Lower Epidermis Xylem Phloem vascular tissue that carries “food to the floor” Leaf Anatomy associated with Photosynthesis Chapter 35

Phloem: food-conducting cells (“Phloem = food to the floor”)  Collenchyma cells (these cells are still alive at functional maturity)- sieve plate elements & companion cells Photosynthesis: Process carried out by plants and some bacteria that converts sunlight into sugar. Vascular Tissue associated with Photosynthesis Chapter 35/36

Bulk Flow - negative pull due to Leaf Transpiration through the xylem’s vessel element. Water moves from high concentration to low concentration, so the lower (more negative) the greater the movement, “Source to sink” - (leaf to root) Sugar made in leaves through photosynthesis travels down with a positive push as the high water potential in the xylem moves toward the low water potential within the sucrose-rich phloem - increases phloem pressure & drives sugar down.
