Key botanical terms( these you are sure to see)

Plant cycles to know

Moss, Fern, Gymnosperm(Pine) and Angiosperm( monocot and dicot )

Advances that led to land plants

1.  Water vascular system

2.  Roots and stems

3.  Loss of dependence on water for fertilization( development of pollen )

4.  Differentiation of tissues

Plant cell types-parenchyma, sclerenchyma, collenchyma

Vascular tissues - xylem - tracheids and vessel elements and phloem- companion cells and sieve tubes

Plant tissues -apical meristem, cambium, mesophyll, epidermis, endonermis, pith, root hairs, stomates, guard cells, and wood

Transpiration and plants

Monocot vs. Dicot

Floral Sex- Pistil, stigma, style, ovary: stamen, anther,filaments, pollen

Ovary- antipodal cells, synergids, polar nuclei,

Seeds- epicotyl, hypocotyl,endosperm,seed coat

Plant hormones- auxins ( IAA ), cytokinins, giberellins, ethylene

Photoperiodiism - far red and near red.  Phytocchromes.  Short day plants and long day plants

Plant lady's corner-

Casparian strips

Guttation

Tropisms
