 Where do plants get their energy?  The Sun’s heat and light give energy to all organisms  Yet, this energy cannot directly start cell processes, it has to be changed into chemical energy  Plants capture energy from the sun… and convert it into chemical energy

 Through Photosynthesis  Photosynthesis: plants use sunlight to form sugar molecules (chemical energy) called carbohydrates  Sugar molecules are made by plants taking in water and carbon dioxide (taken in by leaves)  Oxygen is produced (given off) by plants  Plants are producers

 Photosynthesis  6CO2 + 6H2O+ solar energy C6H12O6+6O2  CO2(carbon dioxide)  H2O= water  C6H12O6= carbohydrates (glucose)  O2= oxygen

 Multi-cellular organisms that have a cell wall and make their own food through photosynthesis  First species of plants did not posses a vascular system (xylem) to carry water up from the roots  2 types of plants: Angiosperms & Gymnosperms

GGymnosperms EEvergreens with needle-like leaves that produce seeds enclosed in cones EExamples: Pine and acorn trees RReproductive method: drops cones to ground AAble to survive through rough weather AAngiosperms FFlowering plants that have their seeds enclosed in fruit EExamples: Flowers and trees RReproductive method: reproductive structures MMale-Stigma (generates pollen) FFemale-ovum PPollen can travel by what 2 ways?

 Discuss two ways that you have benefited from the Plant Kingdom.
