Slide20 l.jpg
One bundle, the water and food.xylem, carries water and minerals from the roots to the leaves. It also supports the great bulk of the plant.

Veins l.jpg
VEINS stem.

  • carry water and mineral from root and stem to leaves

  • carry food that the leaves make to the rest of the plant


2 types of veins l.jpg
2 types of veins stem.

  • Parallel veins run the same direction as the leaf.

  • Netted veins branch out at all angles to cover the entire leaf.






Slide39 l.jpg
Chlorophyll lets the plant use the energy from the sun shining on its leaves to make food out of carbon dioxide and water.


Chlorophyll is what makes leaves green l.jpg
Chlorophyll is what makes leaves green. shining on its leaves to make food out of carbon dioxide and water.

Slide72 l.jpg
When the pollen from one plant is carried to another plant of the same type, it is called cross-pollination.



Slide74 l.jpg
Wind-pollinated called plants shed millions of small, male pollen grains into the air. Few will find a female plant to fertilize, however.
