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 |
