Germination Sprouting of Seed (usually requires a
little light – don’t burry too deep) Soften seed coat w/ water, digestive
acids or fire Breakdown endosperm to supply
sugars for cell respiration – requires oxygen
Growth of new shoot & root
Photosynthesis Light Dependent Reaction
Photon energy used to produce?
Photon energy used to split ? Into ?
Light Independent Reaction ATP energy combines the
H+ with ? To form glucose

Tomato, a fleshy fruit with softouter and inner layers of pericarp
Ruby grapefruit, a fleshy fruitwith a hard outer layer and softinner layer of pericarp
Milkweed, a dry fruit that splitsopen at maturity
Walnut, a dry fruit that remainsclosed at maturity

Wings enable maplefruits to be easilycarried by the wind.
Seeds within berries and other edible fruits are often dispersed in animal feces.
The barbs of cockleburs facilitate seed dispersal by allowing these fruits to hitchhike on animals.
Dandelion seeds dispersed by wind
Leaf functions Capture photon energy & convert to ATP
using chlorophyll Gas exchange using stomata Photosynthesis Transpiration
Transpiration: evaporation of water through stomata, cools plant. W/O loss of water at leaf no water would be absorbed at root (due to capillary action)
Phototropism:Growth toward light
