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
Gymnosperms Evergreens with
needle-like leaves that produce seeds enclosed in cones
Examples: Pine and acorn trees
Reproductive method: drops cones to ground
Able to survive through rough weather
Angiosperms Flowering plants that
have their seeds enclosed in fruit
Examples: Flowers and trees
Reproductive method: reproductive structures
Male-Stigma (generates pollen)
Female-ovum Pollen can travel by what
2 ways?
Discuss two ways that you have benefited from the Plant Kingdom.
