Veins - transport nutrients and water.
Petiole - connects the stem and the leaf.

10. Leaves are Busy

light and carbon dioxide are taken in.
oxygen is released.

12. The Parts of a Flower A bud is a developing flower
Sepal protect the bud

13. The Parts of a Flower Petals – usually colorful
Sepal – protects the bud; sometimes they fall off after the flower is formed

Style – Tube like structure for support
Ovary – Where the pollen goes down. It becomes the fruit
Ovule – Where the seed develops

Imperfect – have only the male or only the female parts on the same flower.

17. Pollination
1)The petals attract birds and insects by their color or smell.
2)The bird or insect moves the pollen from the anther to the stigma.

18. Spreading the Seeds
