  1. How to getfood… A plant isdrawing ressources fromabove the ground surface and below the ground surface… Above the ground : The shoot system (stems and leaves) absorb light in chlorophyllcells and CO2 thanks to leavesstomata. Below the ground : Rootsabsorb water and mineralsthanks to rootshairs. Those exchanges systemsisadaptingregarding the environmental conditions.

  2. How to transport all this… To types of vascular tissues Xylem: Carrying water and dissolvedmineralsupward (xylemsap or « sève brute ») Phloem : Conducting the products of photosynthesisfrom the shoot system to the rest of the plant (phloemsap or « sève élaborée »)

  3. How to protectagainst the eviloutside… • Againtenvironementaggressions: • Stomatalcrypts • Ability for the leaf to roll in bad conditions Againstpredators : -Thorns -Repulsive or toxicsecretions Against the seasonal cycle : -Bud protection -Growth stop -Loss of leaves -Food storage -Dormancy state
