What are the characteristics of spermatophytes?
- The plant has roots, stems, leaves and seed bearing structures.
- They produce seeds.

What plant fertilizes an egg?
Fertilization occurs when pollen grains (male gametophytes) are carried by the wind to the open end of an ovule, which contains the eggs, or female gametophyte. There, the pollen grain develops an outgrowth called a pollen tube, which eventually penetrates to the egg cell within one of the archegonia.
What are the importance of Spermatophytes?
ImportanceToday spermatophytes are by far the largest vascular plant lineage, with about270,000 living species. Ecological ImportanceSpermatophytes are important because they perform a process for obtaining foodcalled Photosynthesis. Photosynthesis is the basis of life.

What is Phanerogamae Cryptogamae?
Cryptogams and phanerogams are two sub-kingdoms of the kingdom Plantae. Cryptogams consist of seedless plants and plant-like organisms whereas phanerogams consist of seed-bearing plants. Cryptogams do not develop flowers and fruits as well. Most Cryptogams do not have a vascular system.

Phanerogams are classified into two groups such as: The word gymnosperm is made from two Greek words “ GYMNO ” which means naked and “ SPERMA ” which means seed. Gymnosperms are naked seed containing plants. These are called primitive seed plants.
What are cryptogams and phanerogams?
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.
