Plant Kingdom
Unit: Diversity of Living Organisms
Syllabus Coverage: Algae, Bryophyta, Pteridophyta, Gymnosperms and Angiosperms
Easy Concept Notes
- Plant kingdom is studied through increasing complexity: simple algae to advanced flowering plants.
- Algae are mostly aquatic and have thalloid bodies; examples include Chlamydomonas, Spirogyra and kelps.
- Bryophytes are amphibians of the plant kingdom; they need water for fertilization.
- Pteridophytes are first vascular cryptogams with xylem and phloem.
- Gymnosperms bear naked seeds; angiosperms bear seeds enclosed within fruits.
- Alternation of generations explains the life cycle with gametophyte and sporophyte phases.
How to Study This Chapter
- Bryophytes lack true vascular tissue.
- Pteridophytes have vascular tissue but no seeds.
- Gymnosperms have seeds but no fruit.
