Study Notes
Major Classes of Plants
- Four primary groups: gymnosperms, angiosperms, mosses, and ferns.
Gymnosperms
- Term "gymnosperm" means "naked seed" in Greek.
- Produce seeds not protected by fruit.
- Examples include pines and redwoods.
Angiosperms
- "Angiosperm" translates to "covered seed" or "enclosed seed" in Greek.
- Flowering plants that produce seeds protected by fruit or pods.
- Classified into two main groups: monocotyledons (monocots) and dicotyledons (dicots).
Monocots
- Seeds have one cotyledon.
- Seedlings display a single seed leaf.
- Vascular bundles are scattered throughout the stem.
- Leaves exhibit parallel veins.
- Flower parts typically in multiples of three.
Dicots
- Seeds contain two cotyledons.
- Seedlings produce two seed leaves.
- Vascular bundles are arranged in a circular pattern.
- Leaves have netted veins.
- Flower parts usually in multiples of four or five.
Scientific Classification
- Scientific names are always in Latin and printed in italics.
- Binomial nomenclature system developed by Carl Linnaeus consists of two parts: genus and species.
- The first name identifies the genus, while the second specifies the species.
- Species can be further divided into varieties.
Life Cycle of Plants
- Three major life cycle groups: annuals, biennials, and perennials.
Annuals
- Complete their life cycle within one year.
- Examples include tomatoes and pansies.
Biennials
- Require two growing seasons to complete their life cycle.
- Examples of biennials are hollyhock and parsley.
Perennials
- Plants that live for more than two years.
- Divided into two classes: herbaceous and woody.
Herbaceous Plants
- Have soft stems that die off during frost.
Woody Plants
- Possess stems and buds that can withstand winter frost.
