What is a plant’s life cycle?
Every plant has a life cycle. It is just
the time period for a plant to go from a
seed to a flower and then pollinate.
These terms will all be covered in the
following slides but if you want to know
about them before hand, you can click
to go to the glossary!

As A Seed
Every plant starts off as a seed.
Whether you plant it in the ground
yourself or it drops onto the earth
itself – it usually has a hard
covering, called a “coat” to protect
itself and is extremely tough.

Germination
 Germination means that seed is
developing into a plant with the
correct amount of sunlight and
water. With these necessities, the
seed will begin to make a new
plant.

Stems and Roots
 As the plant grows, roots will form and
push down into the earth to anchor the
plant into the ground.
 When the roots steady the plant a stem
will grow up through the ground towards
the light.
 The plant will start forming leaves to take
in more sunlight to
help make more food for
the plant through
photosynthesis.

Flowering
Many plants will produce flowers
so that animals or insects will be
attracted to it and will help with
pollination.
Flowers come in many shapes,
sizes, and colors. Some have
fragrances so that attract with a
smell.

Pollination
Pollination is when an animal,
insect or even the wind carries the
pollen that is produced by the
flower to another flower so that
seeds can be produced and the
cycle can start all over again!

Glossary
 Flower – is the reproductive unit of a plant.
 Germination – the beginning of growth of a plant from its seed.
 Leaves – an outgrowth of a plant that grows from a bump in the stem.
Most leaves are flat and their main function is to make food energy
through photosynthesis. The first leaf to grow from a seed is called the
cotyledon.
 Photosynthesis – the process in which plants convert sunlight, water,
and carbon dioxide into food (sugars and starches), oxygen and water.
 Plant – a member of the kingdom Plantae, a living organism that
undergoes photosynthesis.
 Pollen – the male reproductive cell of flowering plants and cone-bearing
plants.
 Pollination - the transfer of pollen from one flower to another.
 Root – a plant structure that obtains food and water from the soil, stores
energy, and provides support for the plant. Most roots grow
underground.
 Seed – the reproductive unit of some plants.
 Seed Coat – the outer, protective layer covering the seed.
 Stem – the axis of a plant; it may be above or below the ground.

Biography
Hello! My name is Lisa
Zmudzinski and I am an
indecisive Gemini from
Edwardsburg, MI. I am 21
years old and am going into
elementary education so
that I will never have the
same day over and over
again. I hate sitting behind
a desk and bananas. People
say that I look more like my
friend Stephanie than I do
my sister and their probably
right. In this picture I was a
rad 80’s girl for a rockin’
cool party.
