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

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
Carbon
Oxygen
Hydrogen
Nitrogen
Phosphorus
Potassium
Calcium
Magnesium
Sulfur
Where are they?
