cell theory and organization Flashcards
Unicellular
1 cell, small, independent
multicelular
many cells,bigger,dependent ,depend on each other,membrane bound organelles
characteristics of cell
cell membrane and DNA
macromolecules
work inside the cell carries it out,( there are different kinds)
organelles
create smaller macromolecules,
tissues
made of many cells that work together to function
major type of tissue
Connective, muscle, nervous, and epithelial
eukaryotic cells
nucleus, most multicellular, their cells have different functions depending on spot in body,
(nerve cell transmit info as electrochemical signals)
organs
Different types of tissue working together to preform a specific job
organ systems
made of 2 or more organs, work together to preform a specific function
cells
Smallest living thing, biological organization
orgainism
Largest level of biological organism, characterististicts: 1 or more cells, react to stimuli, maintain stable equilibrium,
viruses
not living
cell theory
cells come from other cells,all living things are made of cells
ribosomes
in pro and eukaryotic, make protein,produces in nuclous
