In what ways do nonvascular plants, seedless vascular plants, and seed plants differ?

<p>Nonvascular plants lack vascular tissue and use spores to reproduce. Seedless vascular plants have vascular tissue and use spores to reproduce. Seed plants have vascular tissue and use pollen and seeds to reproduce.</p> Signup and view all the answers

How does the absence of vascular tissue in nonvascular plants affect their structure and appearance?

<p>Because they have no vascular tissue to support them or transport water and nutrients, nonvascular plants are low-growing, have thin cell walls, and lack roots.</p> Signup and view all the answers

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.
