Plant Parts
There are four plant parts that we are going to learn about.
Roots Leaf Stem Flower
Plant Part: Roots The first part we are going to learn about is the roots. The roots anchor the plant into the ground.
Plant Part: Stem
The next part we are going to learn about is the stem.
The stem supports the plant. Below is a picture of a plant’s stem.
Plant Part: Leaf
The third part of a plant we are going to learn about is the leaf.
The leaves come in many different shapes and sizes.
Below is a picture of a leaf.
Plant Part: Flower The last part of a plant we are
going to learn about is the flower. The flower petals attract bees and
insects to help pollinate. They also look pretty!
Below are some pictures of different shapes and sizes of flowers.
Functions of Each Plant Part
Now that you have learned and can identify each plant part. You are going to learn about the function of each plant part.
Function means a job. Each plant part has a very important job.
Ready? Lets go!
Function of a Root
The root anchors the plant into the soil.
It also takes in water and minerals from the soil.
Function of a Stem
The stem supports the upper part of the plant.
It also stores food for the plant like water and minerals from the stem.
Function of a Leaf
The leaves job is to make food through photosynthesis.
During photosynthesis, the leaves use light energy to change carbon dioxide and water into sugar (food for the plant).
Function of a Flower
The function of a flower is to make seeds.
Flowers are also important because they are part of the reproductive system of the plant.
The petals on the flower attract bees and other pollinators.
Lifecycle of a FloweringPlant
You have learned about plant parts and each of their functions.
Lastly you are going to learn about the life cycle of a flowering plant.
Ready? Let’s go!
1st Stage: Seed The first stage is the seed. The seed is either lying on the ground or
just beneath the soil.
2nd Stage: Seed begins to sprout If the conditions are right (just right amount of
oxygen, water and warmth) the seed will begin to sprout.
3rd Stage: Developing the leaves and buds
After the seed has been planted, then sprouted, the stem begins to develop leaves and eventually buds.
4th Stage: Plant with Flowers and Fertilization
Once a seed has sprouted and has grown leaves and buds, it then is in its final stage, it grows flowers.
Inside the flowers are tiny seeds. When they are fertilized they produce new seeds. The cycle then starts all over.
