Cells in Organisms
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.
Organisms in this 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
etythrocyte
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. because:
false biological chemicals are unstable
keeps the tissues involved free of 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 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
organ
Two or more tissues which cooperate as a unit are considered a(n)
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: organs 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 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
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 statements describe 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 organs working together for a common purpose
system
Multiple organs which are engaged in a specific process form a(n)
system
. Organisms at this level have their cells arranged into systems
system level
The highest level of 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 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
