14.1 Characteristics ofFlowering Plants

• Angiosperm Classification

2

• Angiosperms are classified into two groups based
  on the number of seed cotyledons (KART uh LEED
  uhns).

3

• Cotyledons are leaflike parts of the plant embryo
  inside the seed.

4
Monocots

• Mono means "one." A monocot seed has only one
  cotyledon.

5

• Monocot leaves are narrow with a parallel vein
  pattern.

6

• Inside a monocot stem, the bundles of vascular
  tissue are scattered.

7

• Monocots have fibrous roots.

8

• The parts of a monocot flower are found in
  multiples of three.

9

• Monocots include grasses and food plants, such as
  corn, and garden flowers, such as tulips.

10

• Palms are one of the few monocot trees.

11
Dicots

• Di means "two." A dicot seed has two cotyledons.

12

• Dicot leaves have a branching pattern of veins.

13

• The bundles of vascular tissue inside a dicot
  stem are arranged in a ring.

14

• Dicots have a large, thick taproot.

15

• The parts of a dicot flower are found in
  multiples of four or five.

16

• Dicots are thought to have evolved before
  monocots. around three times as many dicot
  species than monocot species exist today.

17

• Common dicots include all broad-leafed trees,
  such as oak, maple, cottonwood, and fruit trees.

18

• Food plants such as tomatoes, potatoes, peas,
  squash, lettuce, and broccoli are dicots.

19

• Dicot flowers include sunflowers, roses, and
  violets.
