Cells in Organisms quiz 3 review
amoeba, paramecium, euglena:
cellular
keeps the tissues involved free of disease
leukocyte
Some leukocytes absorb entire bacteria by the process of
phagocytosis
Which statements describe organisms referred to as "colonial"?
similar bacteria
Why do creation scientists believe that God created the "cell"?
because the known principles of chemistry do not support evolution because the proper organic chemicals found in cells cannot form spontaneously or remain in the presence of the earth's atmosphere because the complex chemicals of life can only be produced within and by the direction of a cell.
colonial organisms
cellular
A degree of organism complexity. Organisms in this level are either unicellular or colonial.
cellular level
Organisms that live in a group called a colony.
colonial
the maturation of a cell for a specific function
differentiation
The work being divided up into specialized tasks as in a cell or a society.
division of labor
keeps tissues involved alive, provides oxygen for energy for motion
erthrocyte
Which of the following is a system operation in amoeba?
excretion
A unicellular alga is specialized.
false
Since all muscle cells are specialized, they are necessarily identical.
false
If a particular biological amino acid, protein, or DNA could accidentally form by chance, it could wait around for millions of years (remain stable) while ALL the hundreds of other necessary cellular chemicals were also being formed by accident.
false: because biological chemicals are unstable.
A very long, contracting cell which makes up the muscles of our body.
muscle fiber
causes the actual contraction of muscles to raise leg
muscle fiber
A functioning organism:
must possess interrelated systems can be unicellular can be plant or animal
sends message from brain to move up
neuron
A group of tissues working together as a unit for a particular purpose in the body.
organ
Two or more tissues which cooperate as a unit are considered a(n)
organ
kidney, heart, stomach, liver
organ
tissues arranged into units to perform a function
organ
A degree of organism 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 called a(n) _____.
organism
algae, frog, rabbit
organism
body systems working together for the good of the whole
organism
The highest level of complexity of a living thing in which the systems work together for the good of the whole. Any living thing must be considered to have reached this level.
organism level
______ are the highest level of cellular organization.
organisms
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 organs working together for a common purpose.
system
Multiple organs which are engaged in a specific process form a(n)
system
organs grouped to perform a common process
system
A degree of organism complexity. Organisms at this level have their cells arranged into systems.
system level
The highest level of cellular organization requires the cooperation of multiple
systems
respiratory, digestive
systems
A group of cells working together to perform a particular task.
tissue
groups of cells performing a common function:
tissue
muscle, fat, bone
tissue
A degree of organism complexity. 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 it is also found at the lowest level of cellular organization.
true
No cell is "simple."
true
Some organisms consist of just one cell.
