DO NOW Date: 2/3 Q: How do the structures in plants help them to survive and reproduce? Name three organelles that are present in plant cells and not in animal cells. Can you name their functions? ESSENTIAL QUESTION: How do the structures in plants help them to survive and reproduce? OBJECTIVES: -Video on plant physiology -Neighborhood Plant Tour -Make observations of celery Video • Britannica: Plant Physiology Glossary • Create a new Unit in your notebook. • Create a new three page glossary in your notebook. • Title it “Plants Glossary” • First entry is… Phototropism • the growth response of plant parts to the stimulus of light, producing a bending towards the light source. Neighboorhood Plant Tour • Expectations: – Stay with the group – Be respectful of neighbors’ property – Be aware of cars! DO NOW Date: 2/4 Q: How do the structures in plants help them to survive and reproduce? Do Now: Describe what phototropism is. ESSENTIAL QUESTION: How do the structures in plants help them to survive and reproduce? OBJECTIVES: -Describe and Draw Turgor Pressure -Complete Plant Cell Foldable -Set up Elodea demonstration Plant Cell Foldable Enter the definition for Turgor Pressure into your plant cell foldable, then draw an example of high turgor and low turgor: Turgor Pressure: Pressure exerted by liquid in a plant cell vacuole that presses the cell membrane against the cell wall. Loss of turgor, resulting from the loss of water from plant cells, causes flowers and leaves to wilt. Turgor Pressure Turgor Pressure: a force exerted outward on a plant cell wall by the water contained pg 97 in vacuole of the cell. Turgor Pressure Cell Wall Vacuole Turgor Pressure • Turgor Pressure In Action Flaccid Celery Setup Place a flaccid (wilted) piece of celery in a glass of food coloring and water overnight.

Elodea Demonstration • Blow Carbon Dioxide into Bromothymol Blule to demonstrate the effect of CO2. • Setup elodea plants in a solution of bromothymol blue to demonstrate how plants utilize carbon dioxide and give off oxygen during photosynthesis. DO NOW Date: 2/5 & 2/6 Q: How do the structures in plants help them to survive and reproduce? Describe the Function of each organelle: Large Vacuole Chloroplast ESSENTIAL QUESTION: How do the structures in plants help them to survive and reproduce? OBJECTIVES: -Make new observation of celery -Define and draw Xylem -Observe Elodea Plants -Review/Define Photosynthesis formula Flaccid Celery Setup Place a flaccid (wilted) piece of celery in a glass of food coloring and water overnight. In your notebook, draw the celery ‘after’ water: Celery Turgor Before After Observations:___________ ______________________ ______________________ • Xylem Xylem: Water Highways Define Xylem Xylem: a tissue in plants that is used to transport water and nutrients to different parts of the plant. Turgor Pressure: the internal pressure of a cell created by the presence of water. High Low Turgor Turgor Pressure Pressure Plant Cell Elodea Lab Part 2 • Fill out your observations for Day 1 and Day 2 on your student sheet. Reading • Photosynthesis Photosynthesis • Define Photosynthesis • Complete the equation for photosynthesis.
