require moist environments for cycles.1) Mosses- most numerous; are mostly dioecious (seperate sexes)2) Liverworms- Flat, lobular appearance i.e. Marchantia3) hornwarts- hornlike sporophyte that grows up from a flattened gametophyte. Bryophytes have domminant gametophyte (haploid generation) and dependant (diploid) sporophyte generation Lack xylem; lack true roots, leaves, and stems
type of protazoan like an amoeba
- the most highly evolved protozoans
- posseses a micronucleus (repositiory for genetic info) and a macronucleus(contains some of genetic info found in the micro nucleus)
- e.g. paramecium
Minute bacteria some cause infections in food tract
- -in most an extensive underground hyphal mass sends up vertical hyphae fruiting bodies in which spores formed reproductive structure in fruiting bodies are club-shaped.
There are 12 mammalian orders list 6
- 1) cetacea- whales, dolphins
- 2) Carnivora
- 3) Rodenta- also beavers
- 4) chiroplera- bats
- 5) Artiodactyla- sheep cattle- even # of toes on each foot
- 6) Perissodactyla- horses, rhinos- odd number of toes
Rotofers ( have fixed number of adult cells) and Nematoda (roundworks)
some are heterotrophic, some photosynthetic
Euglena-chloraplast membraneChloryphyll a and bswims using pair of flagellaeyespot helps it orient to light
includes all eukaryotic unicellular speciesdivisions often based on functional characteristics
Include: Protozoans (animal like)
Algai Protists (Plant like)
amoebas and their shelled relativesno cell wallI.E. Foraminetera- Most numerous of protazoas-amoebas w/ snail like shells -calcium carbonate shells (ocean)Radiolariam-shells rich in silicon (more resistent)
Hairlike, single-cell processes that anchor gametophyte to the soil in bryophytes?
Mammalian sub classes?
- 3 Total:
- 1) Protheria (monotremes)- lasck teeth, lay eggs, posses a beak. i.e. platypes, anteater
- 2) metatheria ( marsupials or pouched animals) i.e. opossum
- 3) Eutheria (true or placental mammals)
- are all parasites
- no locamotion
- complex life cycles moving from one host to another
- many gametes, spores produced
- Plasmodium- causes malaria
-Probably the oldest living cells
- branched lipids in membranes
-generally extreme habitats
consists of deuterosomes and protosomes
-are all triploblastic (possessing 3rd laer mesoderm)
lacks cell wall...?
Unique among monerans
Kingdom comprosed of single celled bacteria
-lack nucleus or membrane bound organelles
-posses ribosomes, DNA, and RNA
-lack an ER
Divided into two subkingdoms
-Mesoderm arises from endoderm in the archenterm.
-blastopore forms anus and mouth is formed secondarily
Multicellular Female sex organ that prduces eggs.
Mosses, ferns, and conifers
Present in all complex animals beyond the level of a roundworm
-seperates the gut and the internal organs from the body wall (permits indep.Movement of these two sectors. Thus peristalic movements interior to coelan do not interfere with the cocmotor contractions of muscles in the body.
major groups are purple and green bacteria
often has flagellum
2) Crustacea- gills; i.e. shrimp, crab, barnacles have two pairs of antennae
3) Diplopoda- Millipedes- herbivores, 2 pairs leggs per segment
4) Chlipoda- Centepedes- carnivores
5) Insecta- Most species
-typically divided into 3 body part ( head thorax, and abdomen)
Arthropoda and its classes
