Chp. 1 Bio

Exploring Life

QuestionAnswer
Ecosystem producers, consumers, decomposers.
Producers Covert solar energy into a form their cell can use(chemical energy). plants, photosyntheric bacteria and protists do this by photosynthesis.
Consumers Depend on energy from the producers through cellular respiration. During every transfer of chemical energy, some is lost as heat. animals
Decomposers such as fungi, bacteria, worms, feed on dead organisms. releasing energy that may be used by other organisms.
2 main kinds of cells Prokaryotic Cells and Eukaryotic Cell
Prokaryotic cells are the simplest and smallest cells. They lack a nucleus and membrane bound organelles. Ex. Bacteria, archea.
Eukaryotic cells are more complex. they have a nucleus containing DNA and membrane bound organelles like mitochondria and chloroplasts. EX. plants, animals, fungi.
Taxonomy is the branch of bio that names and classifies species and organizes them into a hierarchy of broader groups. 3 domains
3 Domains Archaea, Bacteria, Eukarya
Discovery science involves observation and analysis of data
Hypothesis-based science involves why questions. Observation/question/hypothesis/prediction/test
Hypothesis a possible answer(or educated guess) to the question.
Archaea contains the Archaebacteria, the ancestral bacteria that live in extreme environments.
Bacteria contains the Eubacteria, E Coli. 1) all bacteria are single-celled organims. 2)all bacteria are prokaryotic - they do not have a nucleus or other subcellular structures.
Eukarya all the other organism, Humans. Eukaryotic cells. 4 kingdoms in the cell Kingdom Protista/Kingdom Fungi/Kingdom Plantae/Kingdom Animalia
Kingdom Protista (Apart of Eukarya domain)- diverse group. eg. seaweed, algea, pond life
Kingdom Fungi (apart of Eukarya domain) - single or multicellular decomposing eg. mushrooms, yeast, molds
Kingdom Plantea (Apart of Eukarya domain) - multicellular producers.
Kingdom Animalia (Apart of Eukarya domain) - Multicellular consumers
