1. Plant Growth

2. Before We Begin... What are the basic parts of a plant?

3. Plant Structure • Roots • The roots are used to stabilize the plant in the ground, and absorb water and nutrients from the soil. • Stem • The stem moves food, water, and nutrients through the plant • Leaves • The leaves help absorb sun light, that allow the plant to make food for itself • Flowers • Flowers are used for plant reproduction

4. Plant Growth • What does a plant need to grow to be strong and healthy? • Water • Water keeps the plant hydrated • Soil • Soil provides plants with the nutrients it needs to grow • Consistent temperature • Just like people, plants need a certain temperature so they do not freeze or overheat • Sun light • Sun light is needed so plants can go through the process of photosynthesis

5. Photosynthesis What does a plant need and what must a plant do to forgo the process of photosynthesis?

6. Recipe to Photosynthesis • Ingredients: • Light Energy- from the sun • Carbon Dioxide (CO2) • Chlorophyll- found in the cells of the leaves • Water- gathered from the soil

7. Recipe to Photosynthesis • Steps to Complete Photosynthesis • 1. The chlorophyll in the leave’s cells absorb light from the sun (light energy) • 2. The sun’s energy splits the water molecules (H2O) into separate elements: hydrogen (H) and oxygen (O2) • 3. The hydrogen combines with carbon dioxide (CO2)- what people breathe out- to make food for the plant • 4. After the food is carried to other parts of the plant (remember it is made in the leaves), the extra oxygen is released! (The very oxygen we breathe)

9. Your Task • Draw and label the process of photosynthesis in your science notebook. Be sure to include all of the steps to the process, as well as plant parts and their names. • *Use your notes to help you draw your picture!
