what are the 8 life processes everything shares
- reproduction
- growth/development
- nutrition
- response to stimuli
- cellular respiration
- excretion
- synthesis
- transport
what are undifferentiated cells?
stem cells
all eukaryotes/protists have ….
histone proteins
every cell has…
- cell membrane (protein synthesis)
- ribosomes
- cytoplasm
- DNA double helix
- macromoleules + monomers (carbs, lipids, proteins, nucleic acids)
examples of kingdom plantae
fern, grass, moss, trees,
heterotrophic decomposers examples
mushroom
yeast
mold
ringworm
athletes foot
paramecium
- mostly unicellular
- some hetero/some auto
- some have cell wall
diversity stems from —
differences in DNA sequences
what is gene expression
process of converting information from one gene to cellular product
genome
all of the genes in an organism
3 domains
- Bacteria
- Eukarya
- Archaea
1st major theme
The process of evolution drives the diversity and unity of life
Darwins theory
- natural selection
- survival of the fittest
- convergent evolution
- everything living has genetic material
what is convergent evolution?
when 2 species that do NOT share a recent common ancestor but end up with similar traits due to the environment around them
2nd major theme
Biological systems utilize free energy & molecular building blocks to grow, reproduce, and maintain dynamic homeostasis
what are some examples of processes that these biological systems utilize to maintain homeostasis?
- metabolism (endergonic/exergonic)
- cellular respiration
- ATP
- krebs cycle
- enzymes
- sexual/asexual reproduction
- glucose oxidation
3rd major theme
living systems store, retrieve, transmit, and respond to information essential life processes
examples of 3rd major theme
- nervous/endocrine system
- adreneline
- fight or flight
4th major theme
Biological systems interact, and these systems & and their interactions possess complex properties
examples of 4th major theme
food webs/chains, food transport, energy pyramid, levels of organization, prey predator relationships
how are organisms classified
domain, kingdom, phytum, class, order, family, genus, species
