Chapter 1 Flashcards
What is a cell
The smallest structural and functional unit of an organism
Atoms join together with what? And then go on to form what?
Atoms join together to form molecules which in turn can make a cell
Tissue
A group of similar cells that perform a particular function
Organs make up what?
Organisms are?
Organs make up several types of tissues and each single one belongs to an organ system
Organisms such as trees are a collection of organ systems
The levels of biological organization
Biosphere

Each organization level with multiple together can do what
For together to create the next level
Ie: organelles can for together to create cellular
Subcutaneous tissue will do what with age
Decrease as you get older then eventually increase
Life belongs in one of the three domains
Domain bacteria (bacteria)
Domain archaea (primitive bacteria)
Domain eukarya (includes four inner kingdoms)
- Protista (alga, Protozoa, slime mold)
- animalia (animals or humans even)
- fungi (fungi)
- Plantae (plants)
Humans are enveloped inside of the eukaryot system. Specifically inside of Kingdom Animalia
Humans are eukaryotes which include hormones, have a nucleus, and are all enveloped inside each other.
Prokaryotes are?
The Bacteria and Archaea domains which both are without a nucleus, are single-celled, and contain prokaryotes
Eukarya contains
Eukaryotes, (cellular organisms, which will contain a nucleus)
Cell classification
- unicellular and multicellular
- Aerobic and anaerobic
Explain protists
Protists are unicellular and multicellular, eukaryotic
Ie: Protozoa, algae, slime mold
Explain plants
Plants are multicellular, eukaryotic and photosynthetic
Explain animals
Animals are multicellular, eukaryotic, and heterotrophic
Explain fungi
Fungi are eukaryotic, decomposes
Ie: molds, yeasts, mushrooms
What is a species?
A species is the smallest unit and can interbreed to produce one or more population
What is genus?
Genus is the second smallest unit and all humans belong to both species and genus.
