bio chapter 1 test

3 domains of life

Bacteria, Archaea, Eukarya

cell types

Prokaryotic (lacks nucleus and organelles) and Eukaryotic (has nucleus and DNA)

six kingdoms

eubacteria, archaebactera, protista, fungi, plantae, animalia

7 levels of classification

domain, kingdom, phylum, class, order, family, genus, species

which kingdoms have prokaryotic and which have eukaryotic cells?

prokaryotic- eubacteria, archaebacteria

eukaryotic- protista, fungi, plantae, animalia

taxonomy + 2 reasons of use

the science of classifying living things

- helps identify organisms

- represents relationships between organisms

species concept

morphological, biological, phylogenetic

phylogeny

history of the evolution of a species

dichotomous key

two-part key used to identify an organism

ancestor

organism from which other groups of organisms are descended

physiology

study of physical and chemical functions of organisms like internal processes and types of proteins they make

4 ways to show how species are related

- similar stages of development

- similar physiological functions

- similar anatomical structure

- similar DNA sequence

homology

similarity in anatomical structure

characteristics of life

Homeostasis

Organization

Metabolism

Growth

Adaptation

Response

Reproduction

homeostasis

maintain stability on the inside while adjusting with environment

genetic diversity

means the variety of inheritable characteristics or genes in a population of interbreeding individuals

classifying types of diversity

- genetic and ecosystem diversity

- Ecosystem Function and Species

Diversity

- Ecosystem Services & Human Actions
