Parts of a Plant
Roots grow down into the soil and
carry water to the plant.
The stem holds the plant up and takes
water to the leaves.
A plant’s leaves help it by making food
from sunlight.
Flowers attract bees to pollinate and
make new flowers.
The pistil and the stamen work
together to grow new plants.
What Plants Need to Grow
–
Air (CO2)
–
Sunlight to make food.
–
Water
–
Soil and nutrients
Plant Lifecycle
From, the seed, roots grow down and the stem (sprout) grows up. Next, the stem
and leaves grow. Later, flowers (buds) grow. The sepal protects the flower
before it blooms. Once the flowers bloom, the stamen drops pollen on the
pistil so that new seeds can grow.

Plant Problems
Touch is harmful to plants. Skin oils
turn petals brown.
Gravity exerts force on the plant’s
structure.
Some bugs, like aphids and snails, eat
leaves and stems, which kills
plants.
Plant Solutions
Scientists have developed solutions, like protective sprays.
And aphid eating insects like ladybugs.
Challenge!
As an extension activity, students may create a newsletter, slideshow, or
publication. Also, students have the option of creating a “mutant plant”
from different plant parts.
