Root: anchors plant, absorbs water+minerals; taproot(dicot) or fibrous(monocot)
Stem: supports, transports water/food; nodes and internodes
Leaf: photosynthesis site; parts: lamina, petiole, veins
Stomata: tiny pores on leaves; gas exchange(CO2 in, O2 out)+transpiration
Flower parts: sepals, petals, stamen(male), pistil(female)
Fruit: ripened ovary; protects seeds; types: fleshy or dry
Seed: contains embryo; dicot(2 cotyledons), monocot(1)
Transpiration: water loss from leaves through stomata
Modified roots: carrot(storage), banyan(prop), orchid(aerial)
Modified stems: potato(tuber), ginger(rhizome), onion(bulb)
Chlorophyll in leaves is the green pigment that captures sunlight
