chapter 25- seedless plants

some characteristics of plants:

sessile (fixed in one place)

photoautotrophic (except for Venus fly trap)

multicellular

cell wall -cellulose and lignin

plastids including chloroplasts

plant cells have

cell wall, central vacuole, and plastids

4 main categories of plants:

bryophytes; mosses

seedless vascular plants; farns

gymnosperms; conifers

angiosperms; flowering plants

bryophytes 

mosses; no vascular transport system to transport water, no seed production, use water for fertilization 

seedless vascular plants:

ferns; has vascular system, no seed production, use water for fertilization

primarily found in aquatic environments:

protista

unicellular with a peptidoglycan cell wall, but no evidence of a nucleus

bacteria

heterotrophic, has a cell wall and a nucleus, decomposer

fungi

multicellular, heterotrophs with no cell wall

animals

penicillin , the best known antibiotic is produced by this organism

fungi

multicellular, autotroph, has cell wall and nucleus

plants

heterokaryotic cells are a feature unique to this organism

fungi

if an antibiotic is effective against a human illness, then this illness is probably cause by this organism

bacteria

most of the phytoplanktons are an example for this organism

protista

non-pathogenic, no evidence of nucleus

archaea

prokaryotic, peptidoglycan cell wall

bacteria

acellular, non-living, cannot reproduce by itself

virus

prokaryotic decomposer

bacteria

genetic material can be DNA or RNA

virus

plasma membrane in outermost lining

animals

a vascular bundle contains

xylem and phloem

a feature unique to fungi is

heterokaryotic cells

if you see mold growing on a old slice of bread, this is most likely to be

zygomycetes

the reproductive structure of Angiosperms are called:

flowers

most gymnosperms are pollinated by

wind

the plant tissue that moves carbohydrates from one part of the plant to another is

phloem

what replaces swimming sperm in the life cycle of seed plants

pollen

if a pine tree in your backyard shows a stunted growth, good explantion for this is;

it doesn’t have enough mycorrhizae in the soil.
