lesson 14
A unicellular alga is specialized.
False
Since all muscle cells are specialized, they are necessarily identical.
False
are the highest level of cellular organization.
Organisms
colonial
Organisms that live in a group called a colony.
muscle fiber
causes the actual contraction of muscles to raise leg
amoeba, paramecium, euglena:
cellular
Some leukocytes absorb entire bacteria by the process of .
phagocytosis
neuron
sends message from brain to move up
Which statements describe organisms referred to as "colonial"?
similar bacteria or protozoa which group together
organ level
A degree of organism complexity. Organisms at this level have their cells arranged into organs.
system level
A degree of organism complexity. Organisms at this level have their cells arranged into systems.
tissue level
A degree of organism complexity. Organisms at this level have their cells arranged into tissues.
cellular level
A degree of organism complexity. Organisms in this level are either unicellular or colonial.
tissue
A group of cells working together to perform a particular task.
system
A group of organs working together for a common purpose.
organ
A group of tissues working together as a unit for a particular purpose in the body.
muscle fiber
A very long, contracting cell which makes up the muscles of our body.
organism level
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.
specialization
The limiting of the function of a cell to a specific function.
division of labor
The work being divided up into specialized tasks as in a cell or a society.
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.
True
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 organic chemicals of life can only be produced within and by the direction of a cell.
colonial organisms:
cellular
Which of the following is a system operation in amoeba?
excretion
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. because:
false biological chemicals are unstable
leukocyte
keeps the tissues involved free of disease
erythrocyte
keeps tissues involved alive, provides oxygen for energy for motion
A functioning organism:
must possess interrelated systems can be unicellular can be plant or animal
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 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
Multicellular organisms exhibit a division of labor among cells known as .
specialization
Multiple organs which are engaged in a specific process form a(n) .
system
organs grouped to perform a common process:
system
respiratory, digestive:
system
The highest level of cellular organization requires the cooperation of multiple .
systems
differentiation
the maturation of a cell for a specific function
groups of cells performing a common function:
tissue
muscle, fat, bone:
tissue
A particular function performed by an arrangement of similar cells is characteristic of .
tissues
