Vocabulary
● Many plants grow from seeds.
● The plant parts that grow out of stems are leaves.
● All plant parts are made of cells.

● A seed needs water to germinate.
● A young plant is a seedling.
● The underground parts of a plant is a plant that take in water and nutrients
from the soil are the roots.

How Plants Make
Food
Roots helps a plant
take in water and
nutrients from the
soil.
Many Plants can form
seeds. Seeds need
air, and water to
sprout. Seeds are
spread in many ways.
Plants make their own
food by a process
called photosynthesis.
Leaves take in carbon
dioxide from the air.
They give off oxygen.
Three ways seeds are
spread are by wind,
Chlorophyll in plants
helps take in light.
water, and animals.

Critical Thinking
 If there were little or no rain for a long period of time, a farmer’s crop
would…
The plants would die from the lack of water unless the farmer provided water to
the plants from another source.
 How can a dandelion growing in the schoolyard be a parent to young dandelion
plants growing miles from school?
Wind can carry seeds from the dandelion great distances.
The seeds may be
dropped in a new location miles away and grow into new plants.
 If a plant reproduces by bulbs, does it make seeds, too? Explain.
Plants that make bulbs also make seeds. It is easier to produce new seeds from
the bulbs.
Process Skills Review
 You are growing two plants. You want to test one plant to find out how
sunlight affects its growth. You will provide the other plant with everything
it needs for growth. Explain how you will observe the plants and compare
your results.
One plant will be provided with water, air and soil, but not sunlight. The other
plant will be provided with air, water, soil and sunlight.
I will observe both plants
and record what happens to them. This allows me to compare the plants to learn
what the role of sunlight is in plant growth.
 What can observing tree leaves help you learn?
Observing different traits of the leaves such as size and shape can help you
identify the type of tree the leaves came from.
