Plant Geneology & Taxonomy
I. NON-VASCULAR PLANTS
No special system of vessels to transport fluids
internally.
• Examples:
mosses, liverworts
II. VASCULAR PLANTS
Special vessel-like system for
transmission of fluids internally.
A. Non-Seed Bearing
Reproduce through spores
• Examples:
Horsetail,
Ferns
II. VASCULAR PLANTS
B. Seed-bearing:
1. Gymnosperms
– Leaves are needle-like or scaly
– Do not produce flowers
– Many produce cones to protect
seeds - conifers
– Seeds not enclosed in fruit
– Stems are woody
• Example:
pines, redwood
II. VASCULAR PLANTS
B. Seed-bearing
2. Angiosperms
– Leaves are flat
– Produce flowers
– Seeds are enclosed in
fruits
– Stems can be woody or
non-woody
– Divided into two groups:
monocots & dicots
II. VASCULAR PLANTS
2. Angiosperms
a. Monocots
– Flower parts in multiples of 3
– one cotyledon in seed
– parallel leaf veins
• Example:
grasses, corn
II. VASCULAR PLANTS:
2. Angiosperms:
b. Dicots
– Flower parts in multiples of 4 or 5
– two cotyledons
– networked leaf veins
• Example:
most other species
