Seedless Plants

what are the two types of vascular tissue

phloem and xylem

In mosses and ferns, the gametophyte generation is

photosynthetic and free living

mosses differ from other bryophytes because their gametophytes

produce structures that look like leaves and stems

unlike bryophytes, lycophytes _______

produce vascular tissue

Describe features of tracheophytes

produce vascular tissue the sporophyte generation is dominant they are found in most terrestrial habitats

gametophyte

the gamete producing phase, produces zygote in which new plant forms

T or F: Bryophytes are non tracheophytes (non vascular)

True

Conspicous, photosynthetic, gameophytes, and the lack of tracheas are feature of

bryophytes

Mosses, liverworts, and hornworts are members of what informal grouping of nonvascular plants?

bryophytes

The closest living descendants of the first land plants are the

bryophytes

The leaves of ferns are called

fronds

Bryophytes are common in what areas

moist areas of the tropics, near stream beds, damp forest floors

seeds are very resistant structures, that can _______ and nourish the young ________

protect, plant

The waxy cuticle and stomata on the above ground parts of the tracheophytes sporophytes function in

reduction of water loss

the three clades of vascular plants are the lycophytes, pterophytes, and _______

seed plants

Ferns, mosses, and seed plant: place in order to the sizes of their gametophyte with group having smallest first

seed plants, ferns, plants

Liverworts reproduce through

sexual and asexual means

Antheridia and archegonia produce which of the following, RESPECTIVELY

sperm and eggs

A common feature of whisk ferns and horsetails is that they both have sperm with ____; for that reason those plants require free water for ___________

sperm, fertilization

Select all statements true about hornworts

their sporophytes have stomata their sporophytes are similar to those in vascular plants their gametophytes are photosynthetic

what is the main evolutionary innovation that helped the tracheophytes to become dominant in many terrestrial habitats

they developed vascular tissue

what is true about whisk fern sporophytes

they lack leaves, they are photosynthetic

Because water availability was a limiting factor for the growth of early terrestrial plant life, such plants likely had the ability to

tolerate desiccation (little water)

what are the functions of roots

transport of water and plant support

characteristics of fern sporophytes

vascular photosynthetic multicellular

the sporophyte of what plant group consists of evenly forking photosynthetic stems that lack roots and leaves?

whisk forks
