Monocots have parallel leaf veins while dicots have branched leaf veins. Safety Precautions: 1. Use care when cutting the seeds with scalpel 2. Exercise extreme care, scalpel are extremely sharp. 3. Inform the teacher if the investigator has a food allergy 4. Wash hands thoroughly before the experiment. Materials: 1 scalpel 1 hand lens Some presoaked seeds, such as beans(Garbanzo), corn. Some stem, leaves, and flowers of various plants, such as Lilly, Kalanchoe. Pre-lab Questions: 1.
The microscopic characteristics that distinguish monocot and dicot are the shape of vascular bundles. Dicots have a circular shape of xylem and phloem in its vascular bundles while monocots have a scattered shape of xylem and phloem in its vascular bundles. 2. The macroscopic characteristics that distinguish monocot and dicot are the number of petals, shape of leaf veins, number of cotyledon, presence of endosperm etc. 3. Washing hands completely after the investigation can avoid unexpected acterial infection and unexpected contamination between different plants samples. Procedure: 1. Dissect one sample of each type of seed to find out whether its embryp has one or two cotyledons. 2. Draw and label the inside of each seed 3. Obtain samples of stems, flowers, and leaves of monocots and dicots. Observe their characteristics to classify the plants as monocots or dicots. 4. Draw an example of each structure you examined. Identify as many differences among the samples as you can. 5. Determine which are monocots and which are dicots.

Xylems and Phloem are in circular shape in dicots, while monocots’ are scattered. Monocots have the multiples of 3 petals while dicots can have 4/5 petals. Monocots have parallel leaf veins while dicots have branched leaf veins. Monocots have endosperm while dicots do not. Conclude and Communicate 1. Monocots have one embryonic seed leave while dicots have two.
Monocots’ seeds have one cotyledon while dicots’ have two. Monocots have the multiples of 3 petals while dicots can have 4/5 petals. Monocots have parallel leaf veins while dicots have branched leaf veins. Monocots do not have the presence of wood, while Dicots have the presence of wood. Monocots’ roots have vascular tissue arranged in a ring. Vascular bundles in stem are scattered throughout ground tissue. The roots of dicots have vascular tissue that arranged in a star shape, vascular bundles in stem are arranged in a distinct ring.
