2. Obtain samples of modified roots:<br />

a. rhizome<br />

b. corm<br />

c. stolon<br />

d. bulb<br />

3. Obtain samples of leaves from different species showing a variety of forms,<br />

arrangement, <strong>and</strong> margin types.<br />

GREENHOUSE<br />

Plant a legume seed <strong>and</strong> a grass seed. Compare <strong>and</strong> contrast germination or emergence<br />

types, the root systems, leaf characteristics, <strong>and</strong> other anatomical differences.<br />

FIELD TRIP<br />
