Two types of plants reproduce by spores rather than seeds . Bryophytes contain no vascular tissue , or the organisation of tube-shaped structure and passages that carry water and food to various piece of a plant . Some plants have vascular tissue but do not give rise seed ; seedless vascular plant have true roots , stems and leaves . Seedless plant must live in moist areas because their sperm , which have tails , require pee to swim to the eggs .

Liverworts

Liverworts ( Hepatophyta ) are bryophytes . There are 6,000 to 8,000 coinage of liverworts worldwide ; they take care like drop mosses but want stem . Their foliage have bass lobe or are segment and are set up in three membership . hepatic are from one - sixteenth to three - fourths of an inch full and half of an inch long . They cling to rocks , the ground , tree , or wherever they can find a place to grow and scatter by spore .

Mosses

Mosses ( bryophyta ) are like liverworts in that they do not have vascular organization . They depend somewhat like hepatic , but they have stems and leaves . Also they have branching rhizoid that cast anchor them to the ground ( liverworts have no rhizoids ) . The rhizoids absorb nutrients and water , but they are not true roots because they miss a vascular organization ; the lack of a vascular scheme fix their size .

Hornworts

The hornwort ( Anthocerophyta ) is another type of bryophyte . Hornworts are plant all over the man growing in dampish or humid place . They are flat and green , sometimes spring up as tiny smoke in cultivated study and garden or on the bark of trees in the tropics .

Club Mosses

lodge mosses ( Lycopophyta ) are seedless vascular works . They have ramify stems that dwell prostrate or creep . thick-skulled cover of leaves that calculate like needles or scales cover their stems and branches . They know in humid region of temperate zones and on hatful in the tropic . Other seedless plants in the same family include spike mosses and quillwort .

Horsetails

Horsetails ( Pterophyta ) are seedless vascular plants thought to be ascendent of modern trees , They grow as hollow , keeled stem . Their leaves are sheaths that gird the shoot . They grow in moist productive soils , often found in soggy fields and at the edge of swamp . Some are evergreen , others place up new shoots each yr from their underground roots . Related plants include ferns and whisk fern . There are an estimated 12,000 specie of ferns worldwide . Because those plant life have vascular organisation , they can grow larger than nonvascular plant .
