  • Types of Angiosperms
  • Botany

2
Angiosperms
  • Angiosperms are flowering plants.
  • Angiosperms belong to the division Magnoliophyta.
  • Angiosperms can be divided into two classes
  • Monocots-Class Liliopsida
  • Dicots-Class Magnoliopsida

3
Class Liliopsida
  • Class Liliopsida contains the monocots.
  • Monocots all have distinct features that make
    them different from other angiosperms.

4
Characteristics of Monocots
  • Monocots have
  • one cotyledon (first emerging leaf from the
    germinating seed aka. Seed leaf)
  • Parallel veined leaves (think of the veins on a
    blade of grass)
  • Scattered primary vascular bundles
  • Monosulcate pollen (has one indention or dip in
    surface)
  • Flower parts in multiples of three (either have
    three of each or have a number that is divisible
    by three)

5
Characteristics of Monocots
Vascular Bundles Scattered
One Seed Leaf Inside Seed
Parallel Veins on Leaf
Three Petals, Three Leaves
6
Class Magnoliopsida
  • Class Magnoliopsida contains the dicots.
  • Dicots are unique flowers. 50 of all dicots
    have woody stems among their other unique
    features.

7
Characteristics of Dicots
  • Dicots have
  • Two cotyledons (seed leaves)
  • Net-veined leaves
  • Primary vascular bundles in rings
  • Floral parts in multiples of fives
  • Tricolpate pollen

8
Characteristics of Dicots

Flower parts in multiples of five
Vascular bundles in rings
Net-veined leaves

Copy and answer the ENTIRE question on your own
paper.
  • 1. You collect a flower specimen while you are
    out on a nature walk. It has 12 pink petals and
    6 leaves with parallel veins around the flower.
    Would you classify this plant as a monocot or a
    dicot? Why?
  • 2. While out on the same nature walk, you
    collect a blue flower. It has five flower petals
    and leaves with webbed veins. It five leaves
    around the petals. Would you classify this plant
    as a monocot or a dicot? Why?
