2) Transpiration
3) Storage
4) Protection
Photosynthesis
CO2 + Light + Chlorophyll – O2 + Carbohydrates
Transpiration
evaporation of H2O
Storage
Cotyledons (cotyledons are not true leaves)
Protection
Brats, scales, and spines are modified leaves
Flowers-functions
1) Reproduction
2) Pollination
3) Fertilization
4) Fruit
5) Seed
Flowers can be reproduced…
1) Annually
