Taxonomy

• Carl Linnaeus, also known as Carl von Linné or
  Carolus Linnaeus, is often called the Father of
  Taxonomy. His system for naming, ranking, and
  classifying organisms is still in wide use today
  (with many changes). His ideas on classification
  have influenced generations of biologists during
  and after his own lifetime, even those opposed to
  the philosophical and theological roots of his

BRYOPHYTA

• Grimmia pulvinata
• with more than 10,000 species in 700 genera. This
  makes mosses almost twice as diverse as mammals.

• This group of 12,000 species contains the ferns.
  Ferns have a vascular system to transport fluids
  through their bodies. They reproduce from spores,
  and vegatatively by extension of the rhizome
  underground. Tropical ferns may be as high as
  trees, but temperate species tend to not exceed
  one metre in height. (Arms et al, 1979)

CONIFEROPHYTA

Conifers are the largest group with the
gymnosperms. They are distinguished by the seed
not being covered by an ovary, refered to as a
'naked seed'. (Arms et al, 1979)

Phylum Angiospermophyta

• This group contains the angiosperms, consisting
  of about 285,000 species. These are distinguished
  by growing their seeds inside an ovary (Greek
  angeion vessel) which is, itself, embedded in a
  flower. After it is fertilised, the flower falls
  away and the ovary swells to become a fruit. This
  group is also known as Anthophyta or
  Magnoliophyta. The forms they take are extremely
  varied, as are the ecological niches they occupy.
