Leaves are organs made of layers of tissues. Tissues are made of cells.
Outside flat cells make up epidermis (the skin of the leaf)
Inner tissue is sponge-like for air to pass
Bottom has tiny openings to let air in and out
Vessels are tubes.

The process that plants and some other organisms use to make sugar for food.
Carbon dioxide + water + sunlight energy  oxygen + sugar
Process happens during cellular respiration.
Process happens in Chloroplasts.

7. Photosynthesis!!! (cont.)
Carbon dioxide – inhaled (breathed in) by the plant through leaves
Water – taken in through the roots of the plant
Sunlight – provides energy for Carbon Dioxide and Water to combine.
Oxygen – what animals inhale (breathe in)
Sugar/Glucose (C6H1206) – food the plant needs to grow and survive.

8. Don’t forget that sugar is consumed by the plant for energy.
