goals
Goals
  • The goal of this presentation is for you to become familiar with what plants need in order to grow as well as the different stages in the life cycle of a plant.
  • At the end of this presentation, there will be a three question quiz on the content learned.
    • In order to achieve the goal of this presentation, all three questions must be answered correctly.
standards
Standards
  • Standards Addressed:
    • “L.OL.02.14 Identify the needs of plants.”
    • “L.OL.02.22 Describe the life cycle of familiar flowering plants including the following stages: seed, plant, flower, and fruit.”
  • These standards are part of the Michigan Grade Level Content Expectations (GLCE’s)
the beginning of a plant
The Beginning of a Plant

Click the flower to watch a video of a seed going through germination! [1]

Back to Quiz Question 1

All plants start as seeds

Seeds come in all shapes and sizes

Seeds go through a process called germination

Germination is when a plant starts emerging from a seed

what does a seed need
What Does A Seed Need?

In order to grow into a plant, a seed needs proper light, water, warmth, and minerals

Without all of these things, a seed will not germinate

parts of a plant
Parts of a Plant

Once a seed grows into a mature adult plant, it has:

Roots

Stem

Leaves

Flower

To help you remember the parts of a plant, click on the picture to listen to a silly song! [2]

roots
Roots

Provide support by securing the plant in the ground

Absorb water and nutrients for growth

  • Two types of roots:
    • Taproot
    • Fibrous
taproot
Taproot

I’m a taproot!

Back to Quiz Question 2

Taproots reach far underground

They have one main root with smaller roots branching off of it

A common taproot that we eat are carrots

fibrous roots
Fibrous Roots

I’m a fibrous root!

Fibrous roots are a bunch of very fine roots

These roots are spread throughout the soil

Common fibrous roots are grass and onions

slide10
Stem
  • Provide support, acts as the plants backbone
  • Carry water and nutrients from the roots to the leaves
  • Move food produced by the leaves throughout the plant
  • Two parts inside the stem:
    • Xylem cells – move water
    • Phloem cells – move food
leaves
Leaves
  • Make food for the plant through a process called photosynthesis
  • Come in many different shapes and sizes
    • Simple leaf – single leaf blade
    • Compound leaf – separate leaflets

Simple Leaf

Compound Leaf

what is photosynthesis
What is Photosynthesis

Back to Quiz Question 3

  • How greenplants make their food
    • Chlorophyll is a pigment that makes some plants green
    • Chlorophyll is the main factor of photosynthesis
  • Carbon dioxide, water, and light energy are changed into glucose
    • Glucose is a sugar that is the source of food used by plants

More on Photosynthesis!

Click the flower to join Mrs. Frizzle and Liz and learn more about photosynthesis! Check out The Facts, play the Factivity, and look at some of the Beyond the Facts websites! [3]

flower
Flower
  • Flowers are used for more than just making a plant look pretty
  • Flowers are important in making seeds
  • The colorful petals of flowersattract pollinators, such as bees and butterflies
    • Pollinators move seeds from place to place, and help new plants to grow!
fruits
Fruits

Some flowering plants also contain fruits

Fruits carry seeds and help plants to keep growing

When the seeds are dispersed, they can get buried

After they’re buried, if given proper light, water, warmth, and minerals the cycle starts all over again!

Hey Second Graders, click the flower to learn more about the parts of a plant and their functions! [4]

why are plants important
Why Are Plants Important?

Plants are an important part of every habitat. Humans and animals use plants as a source of food!

Many medicines come from plants

Plants help control the water cycle

Through photosynthesis, plants take in the carbon dioxide we breathe out, and release the oxygen that we breathe in. We balance each other out!
