Cells in Organisms
Why do creation scientist believe that God created the cells?
-because no known principles of chemistry did not support evolution -because the proper organic chemicals found in cells cannot form spontaneously or remain in the presence of the earths atmosphere -because the complex organic chemicals of life can only be produced with in and buy the direction of a cell
Organisms in the level are either unicellular or colonial
Cellular level
Organisms that live in a group called a colony
Colonial
The work being divided up into specialized tasks
Division of labor
Keeps tissues involved alive, provides oxygen for energy for motion
Erythrocyte
Which of the following is a system operation in amoeba?
Excretion
A unicellular alga is specialized
False
Since all muscle cell are specialized, they are necessarily identical
False
Keeps the tissues involved free in disease
Leukocyte
A very long, contracting cell
Muscle fiber
Causes the actual contraction of muscles to raise leg
Muscle fiber
A functioning organism:
Must possess interrelated system Can be unicellular Can be plant or animal
Send message from brain to move up
Neuron
A group of tissues working together as a unit
Organ
Two or more tissues which cooperate as a unit are considered an __________
Organ
-Kidney, heart, stomach, liver: -Amoeba, paramecium, euglena: -Colonial organisms: -Respiratory, digestive: -Groups of cells performing a common function: -Body systems working together for the good of the whole: -Muscle, fat, bone: -Oregans grouped to perform a common process: -Tissues arranged into units to perform a function: -Algae, frog, rabbit:
Organ Cellular Cellular System Tissue Organism Tissue System Organ Organism
A degree of organisms complexity. Organisms at this level have their cells arranged into organs
Organ level
A functional plant or animal, existing through the cooperative organization of interrelated systems, is calling an ___________
Organism
The highest level of complexity of a living thing
Organism level
_________ are the highest level of cellular organization
Organisms
Some leukocytes absorb entire bacteria by the process of __________
Phagocytosis
Which statement describes organisms referred to as "colonial"?
Similar bacteria or Protozoa which group together
Multicellular organisms exhibit a division of labor among cells known as __________
Specialization
The limiting of the function of a cell to a specific function
Specialization
A group of organisms working together for a common purpose
System
Multiple organs which are engaged in a specific process form a _________
System
Organisms at this level have their cells arranged into systems
System level
The highest level of a cellular Organization requires the cooperation of multiple __________
Systems
Cells working together to perform a particular task
Tissue
Organisms at this level have their cells arranged into tissues
Tissue level
A particular function performed by an arrangement of similar cells is characteristic of ___________
Tissues
An "organism" is considered the highest level of organization of cells, yet is also found at the lowest level of cellular organization
True
No cell is "simple"
True
Some organisms consist of just one cell
True
