Study Notes
Plant Classification Overview
- Nonvascular plants are low-growing and lack true vascular tissue for material transport.
- Vascular plants possess true vascular tissue, allowing effective transportation of water, nutrients, and food.
Key Structures in Plants
- Rhizoid: A rootlike structure found in mosses; anchors the plant and helps absorb water and nutrients.
- Frond: The term used for the leaves of fern plants.
- Pollen: Tiny structures produced by seed plants, containing sperm cell precursors.
- Seed: Contains a young plant and a nutrient supply, all protected by a fruit.
Vascular Tissue Functions
- Phloem: Vascular tissue responsible for transporting food within plants.
- Xylem: Vascular tissue that moves water and minerals from the roots to other plant parts.
Plant Types
- Gymnosperms: Seed-producing plants, their seeds are found directly on cone scales without protective fruit.
- Angiosperms: Flowering plants with seeds enclosed in protective fruit.
Seed Plant Characteristics
- Cotyledon: Leaf produced by a seed plant embryo, often storing nutrients.
- Monocots: Angiosperms with a single seed leaf, parallel veins, and flower parts typically in multiples of three.
- Dicots: Angiosperms with two seed leaves, branched veins, and flower parts usually in multiples of four or five.
Vascular Plant Structures
- All vascular plants feature three main structures: roots, stems, and leaves.
Reproductive Differences
- Nonvascular plants reproduce using spores, lacking vascular tissue for support.
- Seedless vascular plants also use spores but have vascular tissue.
- Seed plants reproduce through pollen and seeds.
Gymnosperms and Angiosperms
- Gymnosperms differ from angiosperms in that their seeds are unprotected, while angiosperms have seeds encased in fruit.
Types of Gymnosperms
- Four main types: cycads, conifers, ginkgoes, and gnetophytes.
