This document summarizes a science lesson on plant reproduction. It discusses how flowers contain seeds and are made up of petals and pistils. Pollen moves from stamens to pistils during pollination, allowing fertilization. Seeds contain embryos and seed coats, and dispersal methods like wind and animals help seeds reach new areas to germinate. The life cycle of flowering plants includes stages from seed to adult plant.

1. Chapter 1 - Lesson 2:
What Do Flowers and Cones Do?

2. SCIENCE BACKGROUND:
· Seeds, which contain a plant embryo
surrounded by a protective seed coat,
grow inside flowers.
· Flowers are made up of petals and
central pistil ( the female part of the
flower) that is surrounded by stamens
(male flower parts). Pollen grains form
on stamen tips (anthers).
· During pollination, pollen moves onto
the stigma, the sticky tip of the pistil.
Pollination allows the mixing of male and
female gametes, which is necessary for
fertilization occur.

3. Science Vocabulary
petal pollen pollinate
1. petal - outside part of a flower that
is often colored.
2. pollen - a fine, yellowish powder in a
flower.
3. pollinate to carry pollen to the
stemlike part of a flower.

Quick Quiz #1
1. What are petals? Petals are an outside
part of the flower.
2. Where are two places you might find
pollen in a flower? Two place you might
find pollen a flower are where pollen is
made (stamen) and the tip of the
stemlike part (pistil).
3. How does the center part of a flower
change as seeds grow? The center part
of a flower swells as the seeds grow.
H.O.T. Which of the following are fruits
and which are vegetables: an apple, a
cabbage, a peper, a tomato, and celery.

Quick Quiz #2
1. What effect do a flower's colors and
smells have on animals?
Flower's colors and smells ___________
animals.
2. What happens when a bee lands on a
flower?
When a bee lands on a flower it brushes
against the pollen and the pollen sticks.
3. What are two ways that a flower can be
pollinated?
A flower can be pollinated by animals such
as a bee or by the wind.
H.O.T. Some plants depend on specific
insects to pollinate them. What might
happen if the insects that pollinate a
particular type of plant were killed by
pesticides? The particular plant will die.

6. Chapter 1 - Lesson 3:
How Do Plants Grow From Seeds?

7. Science Vocabulary
seed coat seed leaf life cycle
1. seed coat - the outside covering of a
seed.
2. seed leaf - the part inside each seed
that contains stored food.
3. life cycle - the stages in the life of a
living thing.

8. Science Vocabulary
germinate seedling conifer
1. germinate - to begin to grow and
develop.
2. seedling - a young plant that grows
from a seed.
3. conifer - a tree or shrub that has
cones.

9. Science Background:
· A seed is made up of a plant embryo,
an outer protective layer called the
seed coat, and one seed leaf or two
that provide stored nutrients for the
developing plant.
· Wind, water and animals help disperse
(scatter) seeds. Seed dispersal makes
it possible for seeds to travel far from
their parent plant to new locations
where conditions may be right for
some seeds to germinate and grow.

Quick Quiz #1
1. What is stored in a seed leaf?
A seed leaf stores ______________.
2. List two ways that seeds can be
scattered.
Seed can be scattered by
__________ and ___________.

11. Science Background:
· A life cycle is a series of stages in the life
of a living organism.
· The life cycle of a flowering plant
includes the following stages: a seed
falls to the ground, the seed germinates,
a seedling grows, the seedling becomes
an adult plant, the plant flowers, its
flowers are pollinated, seeds grow inside
the flowers, fruits form around the
developing seeds, the seeds are
scattered and some seeds begin the life
cycle again.

12. 11-7-14 Science
1. What is a life cycle?
A life cycle is the stages in the life of a
living thing.
2. What is germination?
Germinate is to begin to grow and
develop.
3. How does a seedling get the energy
and nutrients it needs to grow up
through the soil? A seedling gets the
energy from the from the food that is
stored in the seed leaf.
HOT - Why might a seed planted in
very dry soil never grow? A seed
needs water to grow.
