Plant diversity
Bryophytes
-
Roots, stem and leaves cant be easily differentiated
Does not have transporting tissue. But does have chlorophyll for photosynthesis that exist in the entire organism
-
Known as Pioneer Plants because it has the ability to survive in barren and rough places that other complex plants cant live in
-
-
-
-
Reproductive System
Having the alternation between 2 stages in its life cycle: gametophyte and sporophyte. Know as Metagenesis
-
Sporophytes
-
originated from the fertilization between the male gametes (antherozoids) and the female gametes (egg cell)
-
Roles and Benifits
-
Benifits
Marchantia polymorpha, herbs for hepatitic patient
Spaghnum, can be used as a substitute for cotton
-
Pteridophytes
Flourish a damp, cool, shady habitats, although some species also grow in sandy soil conditions
-
They posses true root, stem, and leaves
-
-
Pteridophytes experience 2 stages in its life cycle (gametophytes and sporophytes), the sporophytes stage are the dominant from a whole plants life cycle.
-
Spores (haploid) are produced by a meoisis in a sporangium (sporangia). Sporangia are located in leaf like appendages called sporophyll.
In some genera, like Equisetum, sporophylls might form a distinct and compact structure, called strobilus/strobili
-
Classification
-
-
-
Pteropsida
-
-
leaves: macrophyllous, called as fronds
-

-
Uses of Pteridophytes
Ornamental plants (pteris, Nephrolepis, Polystichum)
-
Medicinal plant (rheumatism, asthma, blood circulation, digestion)
