Unit Two Part One Study Guide Flashcards
What is Eukarya and what makes it special?
it is a domain that has a nucleus to enclose their DNA apart from the rest of the cell
What is Bacteria and what makes it special?
it is one of the domains and it reproduces by producing spores and it causes diseases
What is Archaea and what makes it special?
it is one of the domains and if reproduces by fission and does not cause disease
What are the four kingdoms of Eukarya?
plantae
amelia
fungi
protista
What is the difference between eukaryotic and prokaryotic cells?
Eukaryotic cells are cells containing membrane-bound organelles and are the basis for both unicellular and multicellular organisms; prokaryotic cells do not have any membrane-bound organelles and are always part of unicellular organisms.
What are the purposes and benefits of the classification system?
It organizes all living things and provides a universal way of communication about scientific discoveries/questions
What are the limitations of the classification system?
That the system is constantly being updated as new species are discovered, that is does not prove relationship but only groups the species based on observed relationship, and that not everyone agrees on how the system should be organised
What is the cell theory?
~ all living things are composed of one or more cells
~ a cell is the basic unit of life in all living cells
~ all of the chemical reactions of living organisms occur with in its cell
~ all cells come from cells
Who is Robert Hooke?

What is binomial nomenclature?
it is a two part Latin name of genus and species, it groups genuses and species by homologous trait (basically a very long fancy word that combines the genus and species of an organism into one word)
What is the difference between animal and plant cells?
Animal cells each have a small vaculoe, centrosome, and lysosomes, Plant cells have a cell wall, chloroplasts, and a large central vacuole
What is the difference between unicellular and multicellular organisms?
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, multicellular organisms use many different cells to function
What does the cell membrane/plasma membrane do/what is it?
it is the border or gate of the cell and it is incharge of what comes in and out of the cell protecting it
What does the cell wall do?
it provide structural support for the cell (only in plant cells)
