Plant Parts
Stem
Roots
Leaves Carries water
from roots to other parts of plants and supports plant above ground.
Hold a plant in the ground. They take in water and minerals from the soil.
Take in the air and light
Leaf Shapes
•Wide and flat - maple and oak tree•Small and thick - jade plant
•Smooth or rough edges•Star-shaped - sweet gum•Fan shaped - ginkgo plant
Seed: first stage in the growth of many plants
Seeds come in many different sizes and colors and can even be striped. However, all seeds become plants that look like the plants they came from.
All seeds need water to grow.
This plant has germinated (small plant breaks out of the seed)Root grows from itNext, the seed breaks open and a young plant or seedling appears
Plants that reproduce by seeds usually form more than one seed at a time.
2 Groups of plants form seeds:
•Flowers – grow on bushes, trees or on small plants•Cones – evergreen trees (pine trees & spruce trees)
Cones have hard scales that protect the seeds
under them.
Some plants can be grown from other plant parts:
•Leaf or piece of a stem – placed in water may form roots
Cutting- piece of leaf or stem used to grow new plant
•Tubers and bulbs – underground plant parts also can grow new plants
Bulb – part of stem (this flower grows from bulbs)

Dandelions: form many seeds easily blown by wind
Seeds in watermelon are protected by its fruit.
Stored Food: Used by young plant to grow when seed sprouts
Seed coat : Protects young plant inside the seed
Seedling: lives inside every seed
Seeds are like packages with tiny plant inside. The “package” is wrapped by the seed coat. Inside the seed coat is a seedling and food for the seedling.

•Water

•Animals or people
Cockleburs catch a ride on a shoe
Birds & other animals eat berries , the seeds pass through their digestive systems and are dropped onto the ground far from plant they came from.
Plants can make their own food, unlike people or other animals.
Photosynthesis: food making process
Chlorophyll: green color on plant – chlorophyll helps the plant use energy from the sun to make food.
•Water & carbon dioxide combine inside a plant to make food. (a type of sugar)•Sunlight provides the energy needed for food to be made.
•Plants also make oxygen during photosynthesis. Oxygen is given off through plants leaves.
