The kingdom plantae is classified as follows:
1. Division Thallophyta orAlgae
2. Division Bryophyta
3. Division Pteriodophyta
Differences between Bryophyta and Pteriodophyta.
|Plant body is gametophytic||Plant body is sporophytic.|
|Plant body is either thallose or foliose. However, real stem and leaves are always absent.||Real stem and leaves are present.|
|Fixation of plant body is carried out by rhizoids.||Fixation of plant body is carried out by roots.|
|Sporophyte is parasitic over the gametophytic plant body throughout its life.||The gametophyte is small and independent.|
|Bryophytes are non-vascular in nature.||Pteriodophytes are vascular in nature|
Differences between pteriophytes and Phanaerogams (spermatophytes).
|Pteriophytes||Phanerogams / Spermatophytes|
|They are seedless plants.||They are seed-bearing plants.|
|Gametophytes are small but independent.||Gametophytes are nutritionally dependent on the sporophyte.|
|Their reproductive organs are inconspicuous.||Their reproductive organs are quite conspicuous.|
|Fertilization requires An external water source||Fertilization does not require an external water source.|
Differences between Cryptogams and Phanerogams.
|It contains seedless plants.||It contains plants with seeds.|
|It includes both vascular and non-vasular plants.||It includes only vascular plants.|
|For fertilization, an external water source is required||For fertilization, an external water source is not required.|
Differences between algae and fungi.
|Algae contain photosynthetic pigments.||Photosynthetic pigments are absent in Fungi|
|They are autotrophic.||They are heterotrophic.|
|Most of the algae are aquatic in habitat.||Most of the fungi are terrestrial in habitat.|
|The cell wall is made of cellulose.||The cell wall is made of chitin.|
|Algae contain starch as a stored food material||Fungi contain glycogen and oil as the stored food materials.|
4. Divison Gymnospermae
5. Division Angiospermae
Differences between gymosperms and angiosperms
|In gymnosperms, Sporophylls are aggregated to form cones.||In angiosperms, Sporophylls are aggregated to form flowers.|
|The seeds are naked.||The seeds are enclosed by a fruit wall.|
|The microspores and megaspores are produced by male and female cones.||Microspores and megaspores are produced in the same or two different types of flowers.|
|Vascular tissues such as xylem lacks vessels and phloem lacks companion cells.||Vascular tissues such as xylem contain vessels and phloem contains companion cells.|
|The ovules are not enclosed within an ovary.||The ovules are enclosed within an ovary.|
|Endosperm cells are haploid.||Endosperm cells are triploid.|
Differences between Monocotyledon and Dicotyledon.
|Seeds of Monocotyledon plants have only one cotyledon.||Seeds of Dicotyledon plants have two cotyledon.|
|These plants have fibrous root.||These plants have tap root.|
|The leaves show parallel venation.||The leaves show reticulate venation.|
|The plants are herbs, shrubs with tender stem.||The plants are huge trees with strong stem.|
|The flowers have three or multiple of three petioles.||The flowers have five or multiple of five petioles.|
|Vascular bundles are in ring.||Vascular bundles are scattered.|
The plant kingdom has been classified into ‘cryptogams’ and ‘phanerogams’ based on their seed formation ability.
