Study Notes
Plant Kingdom Classification
- Plant kingdom is divided into various groups based on reproductive structures and life cycles.
- Major divisions: Thallophyta, Bryophyta, Pteridophyta, Gymnosperms, and Angiosperms.
Thallophyta
- Comprises simple plants such as algae.
- Lacks true roots, stems, and leaves.
- Bodies are often autotrophic due to chlorophyll presence.
- Example: Spirogyra, which has spiral chloroplasts.
Bryophyta
- Known as amphibians of the plant kingdom due to their requirement for water for reproduction.
- Lacks specialized conducting tissues for food and water.
- Plant body is typically differentiated into stem-like and leaf-like structures.
- Examples include Moss (Funaria) and Marchantia.
Pteridophyta
- Possesses true roots, stems, and leaves.
- Has conducting tissues, making it more advanced than Bryophytes.
- Reproduces via spores and includes ferns like Nephrolepis and Adiantum.
Gymnosperms
- Seed-bearing plants that do not produce flowers and fruits.
- Reproductive organs are cones, and seeds are exposed.
- Examples include Cycas, Picea, and Thuja.
Angiosperms
- Flowering plants with encased seeds (in fruits).
- Reproductive organs are flowers, showcasing high evolutionary advancement.
- Examples include Mango and Bamboo, which feature natural coverings for their seeds.
Key Comparisons
-
Bryophyta vs Pteridophyta
- Bryophytes need water for reproduction; Pteridophytes do not.
- Bryophytes lack true roots, stems, and leaves; Pteridophytes have them.
- Conducting tissues are absent in Bryophytes, present in Pteridophytes.
-
Angiosperms vs Gymnosperms
- Angiosperms have flowers; Gymnosperms have cones.
- Seeds of Angiosperms are enclosed; Gymnosperm seeds are exposed.
- Angiosperms often showcase a variety of fruit types, while Gymnosperms lack this characteristic.
-
Cryptogams vs Phanerogams
- Cryptogams reproduce via spores; Phanerogams reproduce via seeds.
- Cryptogams include Thallophyta and Bryophyta; Phanerogams include Gymnosperms and Angiosperms.
Monocots vs Dicots
- Monocots
- Single cotyledon in seeds.
- Fibrous root system.
- Parallel venation in leaves.
- Flowers usually in multiples of three (trimerous).
- Dicots
- Two cotyledons in seeds.
- Well-developed tap root system.
- Reticulate venation in leaves.
- Flowers typically have four or five parts (tetramerous or pentamerous).
General Plant Characteristics
- Cell wall and plastids are present in plant cells, distinguishing them from animal cells.
- Non-seed bearing plants do not produce fruits or flowers, classified under Thallophyta and Bryophyta.
- Classification criteria include the presence of conducting tissues and the ability to bear seeds, flowers, and fruits.
