Monocots and dicots

•

This document compares the key differences between monocots and dicots. It begins by explaining that flowering plants are divided into two classes: monocots and dicots. The main differences discussed are that monocots have vascular bundles that are scattered in the stem cross-section, while dicots have vascular bundles arranged in a ring. Examples of monocots include palms, grasses, orchids and onions, while dicots include oaks, roses, mustards, cacti and sunflowers. Images are also provided showing the different vascular bundle arrangements in a monocot and dicot plant.

Differences Between Monocots and Dicots Presented by Crystal Salinas
Agenda  Angiosperm- two classes 1. Monocots 2. Dicots  Differences between monocots and dicots  Identify plants and place them in the two groups
What are they?  Angiosperm - Flowering plants. First appearing at least 110 million years ago from an unknown gymnosperm ancestor, flowering plants have risen to dominance in most of the world's floras. Angiosperms are divided in to two groups: monocot and dicot.
What are they?  Monocotyledons (Monocots) – These plants have specific characteristics that class them as such.  Some examples are: – Palms – Grasses – Orchids – onions
Characteristics of Monocots
What are they?  Dicotyledons (Dicots) – Dicots also have special characteristics.  Some examples of Dicots are: – Oaks – Roses – Mustards – Cacti – sunflowers
Characteristics of Dicots
Comparison of Plants  Monocot is on the left – Oat plant  Dicot is on the right – Bean plant  Notice the difference in the two plants
Vascular Bundle of Monocots  In monocots, the vascular bundles in the stem cross section are usually scattered or more complex of an arrangement as compared to dicots.
Vascular Bundle of Dicots  The vascular bundles in the stem cross section of dicots are arranged in a circle, or ring.
Types of Monocots and Dicots
Review 1. What are three different characteristics that make monocots and dicots different? 2. Are all plants with monocot characteristics monocots? 3. What are some plants that are classified as monocots? 4. What are some plants that are classified as dicots?
