How does the cotyledon differ in monocots versus dicots?In this lab, we will examine the life cycles of the two groups of seed-producing plants: the gymnosperms(which include the conifers) and the angiosperms (the flowering plants), as well as specific plant structand modifications of these structures.Learning objectives of the lab.Through observation, drawing, and identification of living specimens, models, and prepared slidesstudents will learn:d producing plants: gymnosperms and angiosperms, into the plants' life cycles

OPE Examining a flower50 1. Flowers are borne on stalks or pedicels in the axils of modified leaves called bracts. As mentioned previously, flowers may occur singly or in a cluster. Examine at least one of the flowering shoots provided and determine the floral arrangement. (Write the answer in #7.) 2. Using a pair of forceps, remove the outer green sepals of a single flower. Record the number. 3. Remove and record the number of petals. (If more than 12, put numerous.) 4. Remove and record the number of stamens. 5. The structure remaining is the pistil. 6. Use a sharp scalpel to cut a horizontal slice from the ovary. Place this on a slide and observe the cut surface with the stereomicroscope. Observe the ovules. Record the number of compartments or carpels in the ovary. 7. Take another of the same flower. Hold it upside down between the first finger and thumb. Carefully cut it with a scalpel into two halves along the plane of symmetry. Try to cut in a plane that creates mirror images of…

Instructions: 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. Why are terminal buds considered an active part of the stem? 2. Of what importance are nodes to the plant? 3. What are inter nodes and where are they located? 4. What is the function of the lenticels? Do all stems have lenticels? 5. How can you differentiate a monocot plant from a dicot plant just by looking at the stem? 6. What advantage would herbaceous stems have over woody stems? 7. What advantage would woody stems have over herbaceous stems?
