organs Flowers (modified leaves) contain 4 organs: sepals, petals, stamens, pistil.
roots DRIED FIGS: strangler fig usually does not girdle; may shade out host tree. Banyan=Ficus bengalensis.
Ceiba (Kapok, Silk Cotton) = national tree of Guatemala.
Notre Dame completed 1345.
Pneumatophores: Bald cypress knees.
stems POTATO eyes arranged in a spiral.

leaf_morphology JUGLANS NIGRA, GLEDITSIA TRIACANTHOS LEAVES; fruit.
leaves NOPALITOS prickly pear.
Grapevine tendrils are modified stems; prickly pear; ice plant=Aizoaceae; kalanchoe.
dermal SPRUCE NEEDLES: Cuticle = thickened skin surrounding nails; cutin=fatty acids, cutan=hydrocarbon.
plantcells_xylem Water moves laterally thru pits in secondary walls.
ground_tissue Ground tissue internal to vascular tissue=pith; external=cortex.
plantcells_collenchyma CELERY.
plantcells_parenchyma important for photosynthesis; fleshy fruit.
plantcells_sclerenchyma PEAR gritty texture; flax.

0. Axillary bud meristematic cells inibited by produced by apical meristem.
1. Ground tissue internal to vascular tissue is pith, external is cortex.
2. Stele: vascular cylinder, a solid core of xylem and phloem
3. Fusiform initials of the vascular cambium form secondary xylem to the inside and secondary phloem to the outside.
4. Ray initials of the vascular cambium give rise to the xylem and phloem rays.
5. Arabidopsis is the first plant to have its entire genome sequenced
6. Protoplast: cell contents exclusive of the cell wall.
7. Leaf trichomes: outgrowths of the epidermis; aromatic leaves (mint) secrete oils protect from herbivores.
8. Both xylem and sieve-tube cells (phloem) lack a nucleus
9. Bark becomes scaly: cork cambium divides only parallel to surface
10. Rays bands of thin-walled parenchyma cells conduct nutrients and water; not lignified, disintegrate in dead wood, radial splits.
