Question | Answer |
What are the types of plants? | Non vascular/bryophytes
mosses
liverworts
hornworts
vascular
seedless
ferns
seed producing
gymnosperms
angiosperms
monocots
dicots |
What are the characteristics of non-vascular plants/bryophytes? | no vascular tissue
uses diffusion and osmosis for transport of nutrients
one cell thick
sponge like absorbency
pharmaceutical potential
low tangled masses |
What are the characteristics of mosses | used to make diapers by aboriginal peoples |
what are the characteristics of hornworts? | one chloroplast per cell |
How do Bryophytes reproduce? | gametophyte (haploid) generation + soporophyte generation (diploid)
Spends more time in gametophyte stage
relies on moisture a lot for sexual reproduction |
What is the gametophyte generation? | gametophyte produces sporophyte
spores produce through meiosis and are released
spore germinates on the ground=male/female gametophyte
female=archegonium=egg
male=antheridium=sperm
sperm+egg=zygote
goes through mitosis
form sporophyte |
What are the characteristics of seedless vascular plants | taller
sporophyte is the dominant stage of life
less dependent on moisture
ferns |
What are the characteristics of seed producing vascular plants? | reproduce sexually without water
survive harsh environments
can be carried far distances |
what are the characteristics of gymnosperms? | seed not enclosed
includes cone bearing trees
coniferous trees
pine |
What are the characteristics of angiosperms? | produce flowers
90% of plants are angiosperms
seeds contained in a fruit
roses
non coniferous trees
divided into monocots or dicots |
What is the difference between monocots and dicots? | monocots
one seed coat
root xylem and phloem in a ring
vascular bundles scattered in stem
veins are parallel
petals in 3s
dicots
two seed coats
root phloem between arms of xylem
vascular bundles in a ring
veins netlike
petals in 5s/4s |
