Botany
Genesis 1:11, 13
11
Then God said, "Let the land produce
vegetation: seed-bearing plants and trees on the
land that bear fruit with seed in it, according to
their various kinds." And it was so.

And there was evening, and there was
morning—the third day.
Put on your thinking caps and
brainstorm.
What do plants need in
order to grow?

Root
Section 2.1 Vocabulary
Botanist: scientist who studies plants
Botany: the study of plants
Stem: carries nutrients, food, and water to the leaves
Leaf: take in air and sunlight to make food for the
plant
Root: keep the plant in the ground as well as absorb
nutrients and water from the soil

Plant Labeling Activity
• Close your science book.
• Using your memory draw a picture of a
flower and label the four parts.
• Once everyone in your group is finished
swap papers with someone to check your
work.

3.The study of plants is called
__________________________.
Trivia Tree Activity
• Each group will receive two leaves containing
trivia questions.
• It is that group’s responsibility to find the
answer to those questions and write the
answer on the back of the leaf.
• When your group is sure their answer is
correct the leaf should be placed on the trivia
tree.

Oxygen
Carbon Dioxide
Photosynthesis
Chlorophyll
Section 2.2 Vocabulary
Oxygen: a colorless, odorless gas in the air that is
needed for most living things to stay alive
Carbon Dioxide: a colorless, odorless gas that
people and animals breathe out of their lung.
Plants use this to make food.
Photosynthesis: the process that allows green
plants to make food from water, carbon dioxide,
and sunlight.
Chlorophyll: the green coloring in a plant that
captures the sun’s energy.

Section 2.3 Vocabulary
Microscopic: describes something that is too
small to be seen without the use of a microscope
Microscope: an instrument that uses lenses and
light to make it easier for the people to see small
objects.
Cell membrane: the thin covering of a cell
Nucleus: the control center of the cell
Cytoplasm: the jelly-like material that fills the
inside of a plant cell
Cell wall: the stiff layer outside the cell
membrane of the plant cell
Chloroplasts: the tiny green part inside a plant
cell

Pollinator
Petals
Stamen
Pollen
Pistil
Pollination
Section 2.4 Vocabulary
Pollinator: the insect or animal that carries the
pollen to the pistil
Petals: the outside parts of a flower that
attract a pollinator to the flower
Stamen: the part of the flower that produces
pollen
Pollen: a fine powder in a flower that is needed
to make seeds
Pistil: the part in a flower where seeds are
formed
Pollination: the process by which pollen is
carried to the pistil of a flower
Parts of a Flower
Steps of Pollination Activity
Each group should have a baggie with strips of
paper for each group member.
Each group member should empty their pieces
on their desk and try to place the steps in
polination in order.
Once each group member is finished they
should check theirs with other group members.
If there are differences use your book to correct
the problem as a group.
Examining Pollen
Pg. 32
_____ The pollinator brushes against the
stamen and some pollen sticks to its
body.
_____ A seed develops.
_____ The pollinator flies to another flower and
brushes against the pistil, leaving pollen
on it.
_____ A new plant begins to grow.
_____ A pollinator flies to a flower to taste its
nectar.
_____ The seed falls to the ground.
_____ The pollen travels to the ovules.

Plant Propagation
Genesis 1:12
12
The earth brought forth
vegetation: seed-bearing plants
according to their kinds and trees
bearing fruit with seed in it,
according to their kinds. And God
saw that it was good.
Section 2.5 Vocabulary
Plant Propagation

Plant cuttings
Plant Division
Section 2.5 Vocabulary
Plant Propagation: using part of a
plant to increase the number of that
plant
Germinate: when a seed begins to
grow
Plant cuttings: parts of a plant such as
a leaf, stem, or root that can grow to
make another plant
Plant Division: the splitting apart of a
plant to produce new plants
Life Cycle of a Flowering Plant Activity
Each group should have a baggie with strips of
paper for each group member.
Each group member should empty their pieces
on their desk and try to place the steps in the
life cycle of a flowering plant in order.
Once each group member is finished they
should check theirs with other group members.
If there are differences use your book to correct
the problem as a group.
Understanding How Plants Grow
Pg. 34
_____ The tiny plant grows into a mature plant.
a flower bud develops.
_____ The seed falls onto the ground.
_____ Once the flower is pollinated, the petals
die and fall off as the seeds develop
inside.
_____ The flower blooms and the pollination
process begins.
_____ The seed germinates and tiny roots,
leaves, and a stem develop.
