Monocots and Dicots
Monocots and Dicots
There are 2 basic types of plants...monocots and dicots. Each group displays differences in leaves, stems, roots, flowers, and seeds. In this investigation, your team is going to germinate and grow 2 different plants. One is a monocot and the other is a dicot. You will observe the seed, root and leaf differences between the 2 different plants. The stem differences will be analyzed through microscopic study of preserved stem tissue. In addition, you will also research other differences between monocots and dicots. As you differentiate between the 2 groups, think about the trees that you studied. Would they be classified as monocots or dicots?
1. Problem: How do monocots and dicots differ in their seed, leaf, root, stem and flower structure?
2 styrofoam cups per team
Fill 2 styrofoam cups 3/4ths full of potting soil
Place 6 rye seeds that have been soaked in water for 2 days on top the soil in one cup
Place 2 lima beans that have also been soaked in water for two days on top the soil in the other cup
Place approximately 1/2 inch of soil on top the seeds. Add water to the soil.
Put you team names on masking tape and attach the tape to the outside of the cup
Place the 2 team cups on the window sill and observe daily for several days. Add water to the cups if they become dry.
4. Experimental Data:
pictures and information about:
The following is what you are going to have to put on your team wiki page under the heading: Monocots and Dicots. *Each team member is responsible for putting up their own information. I will be checking the team history to determine which member completed certain information.
Required parts and headings you should use (don't use heading 1):
: Research to determine the differences between monocots and dicots. Construct a chart and show differences between seeds, leaves, roots, flowers, and stems of monocots and dicots.
: Create a chart like the one in experimental data above. Complete the data chart, analyze the data collected and finish with a conclusion statement and reasoning for your conclusion.
(Give reasoning for your conclusion). Include in your chart a column for pictures of seeds, leaves, roots, stems, and flowers of the rye, alfalfa and lima bean. You should get the leaf and root pictures from the plants that were grown in class. The stem pictures we will get in the next step. The flower pictures will be taken from the web.
: Examine a monocot and a dicot microscope slide showing a cross section of the stem. Take pictures of each slide using the motic camera (directions are on the
Resources for students link
. Insert the images into the wiki page (remember to name the pictures uniquely to prevent overwriting by others.) Label the pictures with the structures seen and discuss the differences that you observe. Ask yourself: What are you looking at? and What do each of the parts do for the plant?
: Research and list 3-4 examples of herbaceous plants that are monocots and 3-4 herbaceous plants that are dicots.
: Research and list 3-4 examples of trees that are monocots and 3-4 examples of trees that are dicots.(Perhaps a chart would be a way of organizing this information)
: Classify the 2 trees that you studied as either a monocot or a dicot. Give reasoning for your answer. You should not use these for your answer in #5.
Food and fiber
: Identify how those plants from #4-6 are part of our food and fiber system (how plant species directly or indirectly support our populations in the food or other materials we require). Some of the plants classified in the herbaceous monocot family are actually things we eat. The onions and chives are some of the plants we found. The trees that were classified give us oxygen.
Note: To start: ask questions about what do the above terms in the questions mean? Be sure you know what they are before attempting to answer the questions themselves. In your answers, you should address everything you learned so that others understand completely.
As a group, decide which assessment you would prefer:
