Study Notes
Plant Classification Overview
- Plants are categorized based on structure (vascular vs. non-vascular), reproduction methods (seeds vs. spores), and flowering status (flowering vs. non-flowering).
Vascular Plants
- Vascular plants have internal tubes that transport food and water throughout the plant.
- Key examples include ferns, conifers, and flowering plants.
Non-Vascular Plants
- Non-vascular plants lack roots, leaves, seeds, or flowers.
- They reproduce using spores and are typically low-growing.
- Examples include mosses and liverworts.
Classification by Seed Leaves
- Monocots possess one seed leaf in their seeds, examples include grasses, orchids, and grains like corn, wheat, and rice.
- Dicots have two seed leaves, including most trees, roses, beans, tomatoes, and dandelions.
Reproductive Cells
- Egg cells combine with sperm cells to form new individuals.
- Sperm cells join egg cells for reproduction.
Types of Non-Flowering Vascular Plants
- Ferns are flowerless and seedless, reproducing by spores; size varies significantly, with some measuring only a few centimeters while others can exceed 20 meters.
- Conifers are also vascular plants that produce seeds in cones, often retaining needle-like leaves year-round.
Unique Plant Examples
- Duckweed is the smallest flowering plant, measuring under 5 millimeters.
- Liverworts have flattened bodies or stems with overlapping scales, are non-vascular, and reproduce using spores.
Main Groups of Plants
- The four primary groups of plants are mosses, ferns, conifers, and flowering plants.
