Midterm exam Flashcards
only one parent is required no reproductive organs individuals are exact clones of parents quick fission, budding, fragmentation: division of cells
Asexual Reproduction
Two parents Gmates zygote Genetic variation half from each parent
Sexual Reproduction
animals don’t require meiosis
Eggs are formed by mitosis
offspring are clones
Ameoitic parthenogenesis
Haploid Egg: half of the genes
unfertilized
becomes the male
Meiotic Parthenogenesis
Containing both male and female reproductive organs
Don’t have to search around to find a mate
Hermaphroditic
contain both male and female for reproduction
Monoecious
separate male and female
dioecious
came up with the nomenclature
LIinnaeaus
prokaryotic and single celled
bacteria that live in extreme environments
Archaea
prokaryotic and single celled
true bacteria
e.coli and similar
Bacteria
single and multi-cellular
DNA is organized in the nucleus of the cell
Eukarya
Decomposers
break things down to manufacture energy
Fungi
Archaebacteria
Eubacteria
Fungi
Kingdom
Single celled organisms
Protista
Autotrophic
utilize sunlight for photosynthesis
plantae
Eukaryotic
multi-cellular
Animalia
Domain: Ukarya Kingdom: Animalia Phylum: Chordata (backbone) Class: Mammalia Order: Primates Family: Hominoidea Genus:Homo Species: Sapiens
Human Taxonomy
Introduced in 1866 1969: introduced monera Unicellular Lack tissues / organs Life cycle Mutualistic commensalistic Parasitic plant like protists fungus like protists
Protistans
Categorized by how they locomote Amoeboid Flagellated Ciliated Sporozoans
Animal like protists
Cytoplasmic unicellular no organs or tissues organelles nucleus mitochondira
Protozoans
mostly freshwater
mostly nonparasitic/nonpathogenic
get around with cilia
8,000 species
Ciliophora
