Kingdom Classification - Plantae

Characteristics

Multicellular: Organisms in this kingdom are composed of many cells.
Eukaryotic: They possess a true nucleus and other membrane-bound organelles.
Autotrophic: They produce their own food through photosynthesis, using chlorophyll.
Cell Wall: Possess rigid cell walls primarily made of cellulose.
Reproduction: Primarily reproduce sexually, but many also exhibit asexual reproduction.
Habitat: Mostly terrestrial, but some are aquatic.

The plant kingdom is divided into major groups based on key characteristics.

Bryophytes (Non-Vascular Plants):
- Characteristics: Lack true roots, stems, and leaves. Depend on moisture for reproduction. Reproduce by spores. The gametophyte generation is dominant.
- Examples: Mosses, liverworts, hornworts.
Pteridophytes (Seedless Vascular Plants):
- Characteristics: Possess vascular tissue (xylem and phloem). Have true roots, stems, and leaves. Reproduce by spores. The sporophyte generation is dominant.
- Examples: Ferns, horsetails, club mosses.
Gymnosperms ("Naked Seed" Plants):
- Characteristics: Seeds are not enclosed within a fruit. Do not produce flowers or fruits. Most are woody plants.
- Examples: Conifers, cycads, ginkgoes.
Angiosperms (Flowering Plants):
- Characteristics: The most diverse group of plants. Produce flowers and fruits. Seeds are enclosed within a fruit. Have a well-developed vascular system and exhibit double fertilization.
- Examples: Roses, mangoes, wheat.

Algae: Simple aquatic plants (e.g., Spirogyra, Chlamydomonas).
Mosses: Non-vascular plants (e.g., Funaria).
Ferns: Vascular plants that reproduce by spores (e.g., Dryopteris).
Flowering Plants: The most diverse group of plants, reproducing by seeds enclosed within fruits (e.g., Rose, Mango, Wheat).
Conifers: Cone-bearing plants (e.g., Pine, Fir).
