Study Notes
Characteristics of Plant Kingdom
- Multicellular, eukaryotic organisms
- Autotrophic, producing their own food through photosynthesis
- Cell walls composed of cellulose
- Lack of movement and sensory organs
Classification of Plant Kingdom
- Based on characteristics such as body structure, reproduction, and evolution
- Divided into two main groups:
- Bryophytes: Non-vascular plants (liverworts, mosses, and hornworts)
- Vascular Plants: Tracheophytes with vascular tissues (xylem and phloem)
Types of Vascular Plants
- Seedless Vascular Plants: Ferns and horsetails
- Gymnosperms: Seed-producing plants with naked seeds (conifers, cycads, and ginkgoes)
- Angiosperms: Flowering plants with seeds enclosed in ovaries (monocots and dicots)
Plant Structure and Function
- Root System: Underground structures for water and nutrient absorption
- Stem: Above-ground structure for support and transportation of materials
- Leaf: Organs for photosynthesis
- Flower: Reproductive structures in angiosperms
Reproduction in Plants
- Asexual Reproduction: Vegetative propagation through roots, stems, and leaves
- Sexual Reproduction: Production of gametes, fertilization, and seed formation
Ecological Importance of Plants
- Primary Producers: Base of food chains and webs
- Oxygen Production: Release of oxygen through photosynthesis
- Soil Formation: Plant roots hold soil in place, preventing erosion
