Bryophyta
|
1.short stature (mosses), 2.non-vascular, 3.produce spores transported by rainwater and ground humidity
|
|
|
Filicinophyta
|
1. ferns, horsetails, 2.vascular, 3.produce spores transported by rainwater and ground humidity
|
|
|
Coniferophyta
|
1. cedar, juniper, fir, pine, 2.produce woody stems, leaves=needles or scales, 3.use wind to help them reproduce by pollination; seed cones with seed scales
|
|
|
Angiospermophyta
|
1.plants that make flowers and have their seeds surrounded by fruits, 2.have seeds, don't produce cones and aren't always pollinated by wind; relay on birds, insects etc. To transport their pollen, 3.sexual reproductive organs=flowers, fruit holds the seeds

|
|
|
Porifera
|
1.sponges, 2.sessile, 3.fed by pumping water through tissue to filter out food, 3.no muscle, nerve tissue or internal organs
|
|
|
Cnidaria
|
1.corals, sea anemones, jellyfish, hydra, man-of-war, 2.different: sessile/free-swimming etc., 3.tentacles; gastric pouch with one opening
|
|
|
Platyhelminthes
|
1.flatworms e.g. Tapeworm; gut with one opening for food to enter and waste to exit; no heart, no lungs 3.cells need to be close for gas exchange(diffusion)
|
|
|
Annelida
|
1.earthworms, leeches, polychaetes, 2.body divided into sections separated by rings, bristles, 3.gastric tracts with a mouth at one end and the intestines have another opening at the other end where wastes are released
|
|
|
Mollusca
|
1.snails, clams, octopuses, 2.produces shells using calcium, 3.bodies are not segmented
|
|
|
Arthropoda
|
1.insects, spiders, scorpions, crabs, shrimps, 2.hard exoskeleton made with chitin, segmented bodies, jointed limbd(can bend), 3.vary in size, can swim/walk etc.
|
|
|
evolution
|
process of cumulative change in the heritable characteristics of a population
|
|
|
Evidence of evolution:fossils
|
life that exfisted more than 500 million years ago was very different; fossils of fish that have been found are only 500 million years old or less; none of predators existing today lived with dinasoures; many living organism have no identical form in the fossil record
|
|
|
Evidence of evolution:selective breeding of domesticaded animals
|
breeders choose the best male and female to produce offspring with desireable features; may produce unique combination of characteristics that not existed before
|
|
|
Evidence of evolution:homologous structures
|
similar in form and function nut found in dissimilar species; evidence of common ancestor (lim of human, bat and hale)
|
|
|
overproduction of offspring
|
causes struggle for survival, competitions for resources (food etc.) can lead to adaptive behaviour, cooperating with other species
|
|
|
variation in species
|
50% mother, 50% father genetic informatio; random distribution of chormones during spliting in meiosis;
|
|
|
natural selection leads to evolution
|
overproduction - the best adapted are more successful - better chance of reproduction and passing on their genes - over many ggenerations changes may result in evolution
|
|
|
evolution in responce to environmental change (2)
|
(1) bacterial infection - antibiotics - not every bacteria is killed, some odd are resistant - multiplication. (2) rat - pesticides - some are resistant - reproduction
