TOPIC 01-CLASSIFICATION OF LIVING THINGS 

Kingdom Plantae, Division Coniferophyta (Conifers )

DIVISION CONIFEROPHYTA

Coniferophyta is a division containing cone- bearing plants with needle shaped leaves

The smaller male cones produce a yellowish powder called pollen. It contains the male sex cells of gametes. The large female cone bears small seed like structure called ovules. This contains female gametes.

The male cone is comparable to a flower but consisting only of pollen producing structures. The pollen is formed on the leaf like scales of the cone. The female cone is comparable to a flavor but with ovule forming parts only. The ovules are attached to the leaf scales of the cone

The distinguish features and characteristics of the organism in this Division are

  1. They are mostly shrubs and trees, with needle shaped leaves

  2. Their reproductive structures are cones

  3. The ovules are not enclosed inside an ovary wall

  4. The dominant generation is the sporophyte

  5. The majority are evergreen. (they keep their leaves all year round)

  6. They are widely distributed. (are commonly found in areas with cold climate)
