1. And So It Is…. -the remainder of the initial review series.

2. And we have a seed Is it a dicot or a monocot? Meaning, does it have two seed halves? Like our beans—a new plant emerged, from the embryo of the seed, splitting the protective seed coat—this whole process is termed germination.

3. Germination-starts with the absorption of water, which trigger enzyme activity. This in turn sets of processes such as respiration. The absorbed water swells the seed and causes the 1. seed coat to crack. 2. Roots growing from the radicle anchor the seedling in the soil. 3. Then the hypocotyl elongates to produce a young shoot. 1 2 3

4. And the plant “is off to the races” The future nutrition of the young plant is attached to the young stem (hypocotyl) and is either paired (dicotyledon) or in one part (monocotyledon). Both dicotyledons and monocotyledons are small packages of nutrition.

5. Major Plant Tissues: 1.Ground-the most common of all plant tissues-serves as support,storage, secretion and photosynthesis (the work), 2. Dermal-the surface (ex. guard cells-which surround the stomata), 3.Vascular-the xylem and phloem—together they comprise the vascular bundles, 4. Meristematic-the plant’s growth tissue.

6. BOTTOM LINE Key: go through all your notes, use the internet (find sites—great links provided on my school web page), use books, use aunt Edna, whatever. Mucho stuff—just takes repeated exposure (and soaking in)—but this review will be a BIG help, now: what are the major parts of a plant? Answer on back of your ice breaker sheet---use can use your past notes, the book, aquarium fish.
