Photosynthesis

• Photosynthesis is the process of making food by
  plants
  
• The essential ingredients in making this food are
  sunlight, the chlorophyll that is present in
  green plants, water and carbon dioxide in the
  air.

Water is taken in through the roots of the plant
and transported to the leaves by the xylem (tubes
that carry water) in the stems.

• Carbon dioxide animals breathe out from the air
  goes into the leaves through the tiny pores
  called stomata and is spreads to the cells that
  contain chlorophyll in the inside layer of the
  leaf.

Sunlight is used to break down the water in the
plant into oxygen which the plant gives off and
we use to breathe.
10
The hydrogen is then used with the carbon dioxide
to create the food for the plants and ultimately
food for animals as well.
11
Photosynthesis is necessary not just for plants
to make food for themselves, but for animals,
including us eventually.
