cells Flashcards
binomial nomenclature
Two terms used to denote genus and species of a living organism
vacuole
A space within the cytoplasm of a cell typically containing fluid
Cladistics
classification of organisms based on genetic perspective
Eukaryote
has nucleus. Organisms whose cells contain a nucleus and other membrane-bound organelles.
prokaryote
no nucleus. A microscopic single cell organism that has neither a distinct nucleus with a membrane and nor other specialized organelles.
systematics
The branch of biology that deals with taxonomy
Chitin
material that gives strength to exoskeletons
cellulose
an important structural component of the primary cell wall of green plants in many forms of algae
cytoplasm
gelatinous liquid that fills the inside of a cell
homeostasis
The state of steady internal conditions maintained by living systems
cytosol
The liquid component of the cytoplasm of a cell
cell membrane
separates the interior of a cell from the outside environment
flagella
A slender thread, like structure that enables many organisms to swim
protist
A single cell organism
mitochondria
A membrane bound cell organelle in which the process of respiration energy production occur
phytoplankton
microscopic, plantlike organisms that are the base of the marine food web
chloroplast
A plastid that contains chlorophyll in which photosynthesis takes place
zooplankton
small free-floating, aquatic micro organisms
what are the different groups of micro organisms we have studied
plants, animals, bacteria, fungi
what are the 6 common features of the 4 groups of organisms we have studied
1.Reproduction
2. has cells.
3. Grows and metabolizes.
4. has genetic material.
5. responds to environment.
6. maintains homeostasis.
draw a bacterial cell, label the parts, describe the function of parts
cell wall
capsule
genetic material
cell membrane
ribosomes
cytoplasm
flagellum
ribosomes
A minute particle, consisting of RN and proteins
cell wall versus cell membrane
cell membrane separates interior of the cell from the outside environment… The cell wall is the exterior of a plant cell
capsule
The outer layer of the cell that protects bacteria from toxic compounds
