in their lifetime

Parts of a plant
Roots: The roots help to support the plant and also get
water and nutrients from the soil
![Page 6: February 22, 2013Q-2 Pg](https://reader035.vdocuments.us/reader035/viewer/2022062305/56816356550346895dd40589/html5/thumbnails/6.jpg)
• Roots help plants to take up water from the soil (ground).

Table Group Point!
• Roots grow in what soil horizon?
• What is another name for this horizon?
Horizon A Top Soil

Parts of a plant
Stem: The stem gives the plant support and help to move the water and nutrients from the roots to the
leaves
![Page 9: February 22, 2013Q-2 Pg](https://reader035.vdocuments.us/reader035/viewer/2022062305/56816356550346895dd40589/html5/thumbnails/9.jpg)
Parts of a plant
Leaves: The leaves help the
plant to make its own food by
photosynthesis
![Page 10: February 22, 2013Q-2 Pg](https://reader035.vdocuments.us/reader035/viewer/2022062305/56816356550346895dd40589/html5/thumbnails/10.jpg)
Table Group Point!• Plants make their own food through
photosynthesis. This supports which requirement of all living things?
Living things can use nutrients to make energy.
![Page 11: February 22, 2013Q-2 Pg](https://reader035.vdocuments.us/reader035/viewer/2022062305/56816356550346895dd40589/html5/thumbnails/11.jpg)
• Plants make their food in the leaves through a process called photosynthesis.
• Photosynthesis – when plants use light, water, and carbon dioxide to create food Carbon dioxide (C0 ) + water (H 0) + sunlight = food (sugar) + oxygen.
• Plants inhale carbon dioxide and exhale oxygen.

Table Group Point!
• Plants inhale carbon dioxide and produce oxygen. How does that compare to what humans inhale and exhale?
![Page 13: February 22, 2013Q-2 Pg](https://reader035.vdocuments.us/reader035/viewer/2022062305/56816356550346895dd40589/html5/thumbnails/13.jpg)
• Stem - the tube that carries food from the leaves to other parts of the plant.
• This also carries water from the roots to the leaves.
Stem

Apply your knowledge!• Compare this picture to a
plant. Which part of the picture would be the leaves?
• Which part would be the stem?
![Page 15: February 22, 2013Q-2 Pg](https://reader035.vdocuments.us/reader035/viewer/2022062305/56816356550346895dd40589/html5/thumbnails/15.jpg)
What is this?
• A flower?
• Which part is the flower?
![Page 16: February 22, 2013Q-2 Pg](https://reader035.vdocuments.us/reader035/viewer/2022062305/56816356550346895dd40589/html5/thumbnails/16.jpg)
Flowers typically have nectar inside.
Flowers
Flowers - are the parts of a flowering plant where fruits which contain seeds are formed. Seeds help the plant to reproduce.
![Page 17: February 22, 2013Q-2 Pg](https://reader035.vdocuments.us/reader035/viewer/2022062305/56816356550346895dd40589/html5/thumbnails/17.jpg)
Parts of a Flowers
Stamen
Sepals

Petals

FLOWERSPETALS
Petals - are the colorful and leaf-like and are usually around the outside of the
flower. They are sweet smelling to attract the insects and birds.
![Page 19: February 22, 2013Q-2 Pg](https://reader035.vdocuments.us/reader035/viewer/2022062305/56816356550346895dd40589/html5/thumbnails/19.jpg)
FLOWERSSTAMEN
Stamen - the male part of the plant that holds pollen
![Page 20: February 22, 2013Q-2 Pg](https://reader035.vdocuments.us/reader035/viewer/2022062305/56816356550346895dd40589/html5/thumbnails/20.jpg)
FLOWERS
Anther – the tip of the stamen produces pollen and contains plant sperm.

Flowers
If the pollen goes into the pistil, the plant will REPRODUCE and fruits and seeds will form.
PISTIL

FLOWERS
Ovary – the bottom of the pistil; it contains the egg and grows into the plant’s fruit or vegetable after fertilization

FLOWERS
Sepal - the green part that protects the flower bud before it opens.

Now we know how one flower is formed, but how do we get a whole garden full of flowers?
![Page 26: February 22, 2013Q-2 Pg](https://reader035.vdocuments.us/reader035/viewer/2022062305/56816356550346895dd40589/html5/thumbnails/26.jpg)
Table Group Point!
• Just like plants and animals, flowers have to be able to reproduce.
• What requirement of living things supports this?
Living things have to be able to have a population that adapts. Population means more than one.
![Page 27: February 22, 2013Q-2 Pg](https://reader035.vdocuments.us/reader035/viewer/2022062305/56816356550346895dd40589/html5/thumbnails/27.jpg)
PollinationPollination - is the transfer of pollen from the stamens to the pistil.
![Page 28: February 22, 2013Q-2 Pg](https://reader035.vdocuments.us/reader035/viewer/2022062305/56816356550346895dd40589/html5/thumbnails/28.jpg)
What are some ways that pollen might be transferred?
![Page 29: February 22, 2013Q-2 Pg](https://reader035.vdocuments.us/reader035/viewer/2022062305/56816356550346895dd40589/html5/thumbnails/29.jpg)
So that’s how plants are pollinated,
and pollination creates seeds.
Seeds turn into flowers,
and there are flowers all over a garden.
How do seeds end up in different places?
![Page 30: February 22, 2013Q-2 Pg](https://reader035.vdocuments.us/reader035/viewer/2022062305/56816356550346895dd40589/html5/thumbnails/30.jpg)
How do seeds move? Seed dispersal occurs with animals, water, and
wind and explosive mechanisms.

Table Group Point!
• What process that helps the rock cycle could also be responsible for transferring seeds and pollen?

Life Cycle of a Flowering Plant
A seed will germinate, or begin to grown when temperature, moisture, and other conditions are right
A sprouted seed is called a seedling. At first, the young plant gets its energy from the food stored in the seed. After it grow a few leaves, the young plant begins making its own food by photosynthesis
![Page 35: February 22, 2013Q-2 Pg](https://reader035.vdocuments.us/reader035/viewer/2022062305/56816356550346895dd40589/html5/thumbnails/35.jpg)
Germination is when the seed has the right condition to grow

Life Cycle of a Flowering Plant
A fruit contains and protects seed. The fruit ripens, the seeds are released, AND THE CYCLE BEGINS AGAIN
When the plant grows large enough, it produces flowers. Flowers are reproductive structures. After the flower is pollinated, it develops into a fruit.
