1. Plants!

2. What makes a plant? Photosynthesis Cell walls How plants eat
Building blocks

3. Photosynthesis Process of using energy from the sun to make sugar
Sunlight is electromagnetic
Radiant energy visible light
Plants absorb RED and BLUE light
Plants use CHLOROPLASTS to store energy from the sun in sugars
Chloroplasts are inside the leaves of plants

4. Photosynthesis
CO2 +
WATER
CHLOROPLAST
SUGAR +
OXYGEN

5. Plant Cells
All cells have membranes, or flexible containers that keep the cell together while letting certain stuff in and out
Only plant cells also have walls made of CELLULOSE
Walls are for shape, protection, and support
Vacuoles
WATER BALLON INSIDE CARDBOARD BOX
Other kinds of organisms have walls, but not made of cellulose

6. How do plants grow? Annual (an-you-al)- year
a plant that completes its life cycle in one growing season
Growing
Flowering
Setting seed
Tomatoes Marigolds

7. How do plants grow? Perennial (per-en-ee-al)= year to year
a plant that lives for 3 or more years
Every year it grows, flowers and seeds
Sometimes the plant’s roots re-grow new stems
Other plants have stems that keep living, like trees
Roses Spruces Daisies

8. How do plants grow? Biennial (by-en-ee-al)= two years
a plant that needs 2 growing seasons to complete its life cycle
The first year it only grows lots of leaves
Then it rests over winter
The next spring it grows flowers and will set seed
Carrots Foxglove

9. Plant Structure Leaves Stems Roots Special parts Flowers Cones
Thorns and vines are special leaves!
Stems
Roots
Special parts
Flowers
Cones

10. Basic Plant Forms
Tree
Shrub/bush
Vine
Forb
Grass
Aquatic plant

11. Roots Responsible for pulling up water and minerals
Anchor the plant to one spot

12. Shoots Stems and leaves
Trunks and branches are kinds of stems
Plants grow at special ends of stems call terminal buds
Leaves grow at nodes along stems

13. Shoots
Problem: food is made at the top and water is sucked up from the ground…
XYLEM (zy-lem): moves water and minerals through the tree, helps support the plant
PHLOEM (flow-em): moves food from leaves to other parts of plant
Borrow or find tree cookie

14. Special Structures Different parts = different advantages Flowers
Cones
Fruit
Storage

15. Flowers
Making seeds
Attracting pollinators
petals

16. Fruits and Seeds
Plants build fruits to protect and help spread their seeds
Seeds contain tiny plants, waiting for the right conditions to germinate and grow
Coat
Food supply
