Concepts of Biology Ch.7.4 review

Unicellular Organism
a single celled organism
bacteria, algae, yeast, paramecium, amoeba
examples of unicellular organism
colonial organisms
organisms that are made up of groups of cells of the same species that live attached to one another but have few specialized structures
example of a colonial organism
multicellular organisms
organisms that are made up of many cells that work together
cell specialization
each different type of cell has a different job or role in the organism
division of labor
cell specialization
cell interdependence
three traits that multicellular organisms exhibit that unicellular organisms do not exhibit
Multicellular organisms characteristic
kind of organism where cell specialization is a characteristic
Individual cells
organ systems
4 levels of biological organization from most simple to most complex
Red blood cells-transport oxygen
pancreas cells-produce proteins
muscle cells-allow movement
three examples of animal cells and what they are specialized for
Stomata-allow gas exchange through the openings
example of a plant cell and what that cell is specialized for
stomata-allow gas exchange through tiny openings
guard-surround stomata and regulate this exchange of gases
what stomata and guard cells do in a plant
a group of similar cells that perform a particular function
epithelial tissue-covers body surfaces
nervous tissue-sends messages
connective tissue- connects body parts
muscle tissue-allows bodily movement
four examples of different types of tissues in animals and what they do
groups of tissues that work together to perform a specific function
heart-pumps blood through out the body
lungs-help you breathe
skin-provides covering
different organs and what they do
Organ system
a group of organs that work together to perform specific function
level: organ
level of organization represented by the eye
muscle cells have
a large number of the organelle mitochondria
pancreas has
a large number of the organelle ribosomes
