DISTINGUISHING BETWEEN THE TWO

TYPES OF FLOWERING PLANTS ACTIVITY

MATERIALS NEEDED: Prepared slides of Monocot and Dicot stems, roots, and leaves! Examples of a monocot plant and a dicot plant if possible!

PROCEDURE: MAKE ALL OF YOUR SKETCHES ON THE BACK OF THIS PAPER

1. Examine the leaves of the live specimens! Observe the differences in the pattern of veins on the leaves!
2. Sketch each leaf, including its vein pattern (TWO SKETCHES – ONE MONOCOT, ONE DICOT)
3. Count the number of petals on each of the monocot and dicot flowers!
4. Look closely into the flower! Count the number of stamens in each type of plant!
5. Sketch and label the prepared slide of monocot and dicot stems (TWO SKETCHES – ONE MONOCOT, ONE DICOT)
6. Sketch and label the prepared slide of monocot and dicot leaves (TWO SKETCHES – ONE MONOCOT, ONE DICOT)
7. Sketch and label the prepared slide of monocot and dicot roots (TWO SKETCHES – ONE MONOCOT, ONE DICOT)

CONCLUSIONS:

1. How do the veins in a monocot leaf differ from those in a dicot leaf?

 

 

 

 

 

2. Compare the number of petals on a monocot flower to the number on a dicot flower.

 

 

 

 

 

3. Compare the number of stamens on the monocot flower to the number on the dicot flower.

 

 

 

 

4. How does the arrangement of vascular bundles in a monocot stem differ from the arrangement in a dicot stem?

 

 

 

 

5. What are two functions of the vascular bundles seen in these stems?

 

 

 

 

6. A plant has parallel veins and three petals on its flower. Is it a monocot or a dicot?

 

 

 

 

7. A fossil of a plant is found and the veins in the leaves branch repeatedly. How many cotyledons does its seed have?
