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
