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.
