I. Look for representative specimens of herbaceous dicot and monocot stem. The external parts that can be observed are nodes, internodes, leaf scar, lenticel, and buds (axillary and terminal). Examine and compare their external morphology by answering the questions below:   1.. What is the function of the lenticels? Do all stems have lenticels? 2. How can you differentiate a monocot plant from a dicot plant just by looking at the stem? 3. What advantage would herbaceous stems have over woody stems? 4. What advantage would woody stems have over herbaceous stems?   II. Compare the internal anatomy of stems of xerophytes, mesophytes, and hydrophytes. Relate differences to the nature/habit of the different plants.

Given below is an experimental setup to demonstrate a particular tropic movement in germinating seeds. Study the diagram and answer the questions that follow Perforated trough Moist sawdust - Germinating seed -Brick (i) Label the parts 1 and 2. (ii) Name the tropic movement shown by part 1.
