Seeds and Growing Plants Workbook of: _________________

Parts of a plant Roots – take water from the soil Stem – support the plant, transport water and nutrients Leaves – Do PHOTOSYNTHESIS to create energy for the plant Photosynthesis = Using energy from sunlight to create food Flowers – attract pollinators Stamen – pollen on top Pistil – needs pollen to create seed

Seeds look different – inside and OUT  Look at a seed with your eyes, record OBSERVATIONS SEED:__________________________ OBSERVATIONS: __________________________ __________________________________________  Look at a seed with a microscope SEED: ___________________________ OBSERVATIONS: __________________________ __________________________________________

Seeds  Match the word to the part of the seed and plant!  Hypocotyl  First leaves  Radicle  Epicotyl/stem  Cotyledons/endosperm  Root

GERMINATION What is germination? GERMINATION  ___________________ __________________________________ Steps: 1.Seed coat breaks 2.Radicle becomes ROOT 3.Hypocotyl and epicotyl become the STEM 4.First leaves grow  photosynthesis

Plants need NUTRIENTS Nutrients = Chemicals that are needed fro growth Plants need Where are they? Carbon Oxygen ________________ Hydrogen Nitrogen Phosphorus Potassium _________________ Calcium Magnesium Sulfur

pH of Soil pH = measure how acidic or basic something is  What is the pH of each soil sample? pH=

CONDITION: SOIL? SAND? SUN? SHADE? (circle what you have) PLANT #Height (cm)# of Leaves TOTAL AVERAGE WEIGHT OF ALL THE PLANTS:

What conditions are the best for plant growth? Water Sunlight Soil - pH, - nutrients Under what conditions did our plants grow the best? ____________________________________ Why? ________________________________ _____________________________________
