Phanerogams are seed bearing plants. These are most advanced plants. The word Phanerogams (or Phanerogamae) is made up of two Greek words “FANEROS” which means evident and “GAMOS” which means marriage. These are also known as spermatophytes. The word spermatophyte is also made from two Greek words “SPERMA” which means seed and “PHYTON” which means plant.
In 1883, A.W. Eichler classified the whole plant kingdom into two sub-kingdoms such as cryptogams and phanerogams. This is traditional of classification of plants and is still followed by many botanists.
Phanerogams are terrestrial plants and more advanced than the cryptogams. These are also called as flowering plants.
Following are the characteristic features of phanerogams:
1.They have well-differentiated plants i.e. the plant body is divided into distinct root, shoot, and leaves.
2.These are multicellular, eukaryotic and chlorophyll containing plants.
3.These are photoautotrophic and produce own food by photosynthesis.
4.These are flowering plants.
5.These have vascular system i.e. xylem and phloem tissues.
6.These are higher terrestrial plants and can be found in deserts, on mountains, and in rainforests.
7.Here the reproductive organs are found in the flowers and are visible.
8.The life cycle of phanerogams is completed in two generations sporophytic generation and gametophytic generation. This is also known as alternation of generation.
9.The plant body is a sporophyte and diploid.
10.The gametophytic phase is much reduced in phanerogams.
