What is the difference between between Flowering plants and non flowering plants?

Question

What is the definition of plants? Key words:Classification of plants,Fertilisation method, Land/Water plants,Roots,stems,suckers,leaves?
P.S. Write some examples

Answer 1

Non flowering plants:
1. Earliest Vascular Plants: The oldest fossilized vascular plant Cooksonia was discovered in both Europe and North American Silurian rock. True roots and leaves were absent; with the largest species being 50 cm. tall.
2. Ferns. These are the most well represented of the seedless plants. Most ferns have fronds, compound leaves divided into several leaflets. As the frond develops it uncoils from a structure called a fiddle head. Ferns are homosporus with the leafy plant the sporophyte. The sporangia are located on the under surface of the fronds in areas called sori. The gametophyte is a free-living, small, fragile structure. Water is necessary for fertilization since the sperm must swim to the archogonium, where fertilization takes place.
3. Gymnosperms: As the climate began to dry out the large Fern forests began to be replaced by a new type of plant the gymnosperm. This plant had vascular tissue and a new type of reproductive structure called the seed. These plants contained these seeds in structures called cones. The leaves of most of the gymnosperms are needle -like structures. These needles contained a thick cuticle and reduced stomata. The conifers are heterosporus (male and female gametes develop from different types of spores on different structures).

Flowering Plants: are the most widespread and diverse. The division Anthophyta is divided into two classes, Monocotyledonae and Dicotyledonae. The development of the flower allow this group of plants take over most biomes on earth. The life cycle of the Anthophyta is similar to that of the gymnosperms. The gametophyte stage is small and microscopic. The male gametophyte is the mature pollen grain while the female gametophyte is the embryo sac, located in the ovule.

Answer 2

Difference in how they reproduce, since non-flowering would not have seeds. Maybe by taking a cutting or by a root system spreading underground or by making roots/plants above ground as "babies" (ie Hens and Chicks plants or tomato plants (but that flowers too) or strawberry plants).

Answer 3

Flowering plants use sexual reproduction to produce seeds which are a combination of genes from two different plants.

Nonflowering plants use asexual reproduction to produce spores which contain the genetic material from only one parent.
