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 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.
