Take 5 Monocots and Dicots
#1 RESEARCH: 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.
major leaf veins are parallel
major leaf veins are reticulated
one embrionic cotyledons
two embrionic cotyledons
tracheary elements may be absent from the center
develop from the radicle
multiples of three
multiples of four or five
vascular bundles are scattered
vascular bundles are in a ring
#2 EXPERIMENTAL DATA: Complete the data chart, analyze the data collected and finish with a conclusion.(Give reasoning for your conclusion).
Description and Picture of:
The alfalfa seeds are yellow or olive green to brown. They are irregularly reniform.
The ground ivy seeds are square, trailing, rooting at the nodes. They are mostly without hair but occasionally with short, stiff backward-pointing hairs.
The yucca seeds are blackish gray and are in the shape of a kidney.
The alfalfa leaves are pinnately trifoliolate with the terminal petiolule longer than the sides petiolules. Leaflets are toothed or serrated.
The ground ivy leaves are opposite, nearly round in outline or sometimes kidney-shaped, on long petioles. Margins have large rounded teeth and leaf veins arise from the same point.
The yucca leaves are very long and smooth.
The alfalfa has an extensive taproot which may penetrate the soil 23-30ft. Fibrous roots proliferate in the upper 8 inches of the soil.
The ground ivy roots are rhizomes occur and fibrous roots are also produced at the base at each node of the trailing stem.
The yucca roots long, pointy, and come out of what looks like to be a big root, but is the under ground stem.
Ground Ivy is a monocot. Their major leaf veins are parallel and their flowers come in multiples of three.
Lima beans are dicots. They have one primary root with secondary roots branching off. Also their leaves are reticulated.
#3 STEM SLIDES: Examine a monocot and a diccot microscope slide showing a cross section of the stem. Take pictures of each slide using the motic camera.(Motic instructions given on Resources Page) Insert the images into the team wiki page. Label the pictures and discuss the differences that you observe.
File Not Found
The corn is the monocot. The xylem tubes are the little "bubbles" in the vascular bundles. The phloem tubes are the little "bubbles" in the vascular bundles. We measured a air space and it was measured 407.59000 um.
File Not Found
The tilia is the dicot. The xylem tubes are the inside tubes that are closest to the center. The phloem tubes are the ones closest to the outside. When we measured, we measured the xylem tubes. They came out to be 2617.33596 um.
#4 HERBACEOUS PLANTS: Research and list 3-4 examples of herbaceous plants that are monocots and 3-4 herbaceous plants that are dicots.
Four examples of herbaceous dicots are Primula, Buttercup, Turnsole, and Mint. One example of a herbaceous monocot is Lemon Grass. Another example of a herbaceous plant is Ginger and Orchid.
#5 WOODY PLANTS: 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)
Oaks, Maples, and Sycamore are all examples of a dicot tree. One example of a monocot tree is the Mountain Cabbage Tree. Another example of a monocot tree is Balsam Fir and Green Alder.
#6 INDIVIDUAL TREE CLASSIFICATION: Classify the 2 trees that you studied as either a monocot or a dicot. Give reasoning for your answer.
Black Cherry and the American Chestnut is a dicot because the Class name of the tree is Magnoliopsida which is a word from the Takhtajan system and the Cronquist system which means dicotyledon. I also know that because the veins are not parallel. Tom Wagner
Quaking Aspen is a dicot. I know this because the Class name of the tree is Magnoliposida which is a word from the Takhtajan system and the Cronquist system which means dicotyledon. The word dicotyledon means dicot. The Tulip Tree is a dicot. I know that it's a dicot because
the veins are not parallel, and if they were parallel it would be a dicot.-- Kristen Fedder
Anna Monyak-The Honey Locust is a dicot because its major leaf veins are reticulated and the flowers usually come in multiples of four or five. The Eastern hemlock is neither since it is not a flowering plant and not classified under a flowering classification.
#7 Identify which plants that you listed from steps 4-6 are a part of your food and fiber system on earth.
For ginger it is pickled in vinegar, stewed in boiling water to make tea, it is also used in candy as a flavoring for cookies, crackers, and cake. It is also the main flavor in ginger ale, and it is used in gingerbread , ginger snaps, ginger cake, and ginger biscuits.
For buttercup it is used for yellow spices.
Mint is used for teas, beverages, jellies, syrups, candies, and ice creams.
Lemon grass is used for teas, soups, and curries, and is often used with seafood, poultry, and fish
Orchid is used for flavoring, and powder for cooking.
For the Black Cherry tree we use the cherries for soda flavorings, jellies, pies, and ice creams.
Oak tree is used for smoking fish, meats, which is put into wines.
Maple tree is used for maple products such as syrup, taffy, sugar.
The American Chestnut is used for the chestnuts it drops during the fall which many people eat.
The Quaking Aspen is used for making bitter from the bark and leaves.
The Honey Locust's pulp is used for making beer.
The Tulip Tree is used for making honey from the blossoms.
The phloem tubes are the closest to the outside and the xylem are the closest to the inside.
