3es. Chat is nonvascular plantB

3Eonvascular plants don1t contain tissues to transport water and nutrients throughout the body of plants.

3Very good Give the three divisions of  nonvascular plants.

3he three divisions of nonvascular plants are bryophyta, hepatophyta, and anthocerophyta.

3I observed that the plants have cone8li)e in the center and its leaves resembles the  palm leaves.

3Gymnosperms are seed8bearing vascular 

 plants in which the seeds are not enclosed in an ovary. 3Very good Gymnosperms are referred to as 3na)ed seeds. hey do not produce flowers. Chat are the four divisions of GymnospermsB

3he four divisions of gymnosperms are cycadophyta, gin)gophyta, gnetophyta, and coniferata.

3Although classified as a single group, gymnosperm plants are actually comprised of four different phyla. Chat are the characteristics of cycadophytaB 3hat1s right hey have a distinct trun) with a few functional leaves atop. hey are often mista)en for palms. And have large, compound leaves. Fne of the eamples of cycadophyta is the cycads. -ycads bear large cones. Chat are the characteristics of gin)gophytaB

3es. he only living member of the  phylum Gin)gophyta is the !aidenhair tree, better )nown as Gin)go biloba. It has fan8shaped leaves, uniue among seed  plants because they feature a dichotomous

3-ycadophyta are characteriphedra has small, scale8li)e leaves.

3he stem of Celwitschia is shaped li)e a large, shallow cup that tapers into a taproot  below the surface. It has two strap8shaped, leathery leaves that grow continuously from their base, splitting as they flap in the wind. Chat are the characteristics of >phedraB 3es. >phedraHs small, scale8li)e leaves are the source of the compound ephedrine, which is used in medicine as a potent decongestant. *ecause ephedrine is similar to amphetamines, both in chemical structure and neurological effects, its use is restricted to prescription drugs. he last genera is the Gnetum.

3he seeds of Gin)go biloba are usually used for food they can be roasted or put into a soup.

3Chat is the economic importance of Gin)go bilobaB 3-onifers are used in timber and paper   production. 3hat1s right he wood is sometimes used for religious furniture. he wood from the female tree can be made into paper. he leaves and JnutsJ are used for medicine all over the world. his medicine has been used to treat asthma, coughs, bronchitis, digestive aid and urinary incontinence. Chat about the conifersB 3es. Gymnosperms provide the entire worldHs softwood timber, the maKor construction wood of temperate regions, and about 46 percent of the worldHs annual lumber production. 1. Generali2ation
