The Plant Kingdom 4 General Characteristics: 1) Multi-celled organisms 2) Plants make their own food by photosynthesis 3) They have chloroplasts- organelle where photosynthesis takes place • they’re green because they have chlorophyll Chlorophyll- • the chemical that gives plants their green color • traps light energy for photosynthesis 2

4 General Characteristics Cont’d 4) Plant cells have cell walls (animal cells do not) cells walls • stiff cell walls give structure to each cell • also supports the plant • made of cellulose • have holes through which cells share cytoplasm & pass nutrients sugars, water, and hormones 5
Photosynthesis: Prefix photo means: Light Root word synthesis means: to make Photosynthesis Process in which plants use water, carbon dioxide, and energy from the sun to make food • only occurs in the chloroplasts • releases oxygen 6
What process is illustrated here? Photosynthesis 6 CO 2 + 6 H 2 O + light energy = C 6 H 12 O 6 + 6 O 2 7
