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 Turgor Pressure: 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 pg 97 Turgor Pressure Turgor Pressure: a force exerted outward on a plant cell wall by the water contained in vacuole of the cell. Turgor Pressure pg 97 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. In your notebook, draw the celery ‘before’ water: Celery Turgor Before After

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 Turgor Pressure Low Turgor Pressure Plant Cell

Elodea Lab Part 2 Fill out your observations for Day 1 and Day 2 on your student sheet.
