CHARACTERISTICS OF LIFE

Question 1

The most common feature of every living organism is life.
There are nine essential characteristics of life.
(TRUE OR FALSE)

Answer 1

False (Correct Answer: There are six essential characteristics of life.)

Question 2

It is a specific interrelationships among the parts of an
organism and how those parts interact to perform
specific functions. Living things are highly
organized.

Answer 2

Organization

Question 3

All organisms are composed of one or more cells and
cellular function depends on the precise organization
of large molecules.

Answer 3

True

Question 4

Disruption of this organized state can result in loss

of functions or death

Answer 4

True

Question 5

It is the ability to use energy and to perform vital functions.

Answer 5

Metabolism

Question 6

It refers to all of the chemical reactions taking place in

the cells and internal environment of an organism.

Answer 6

Metabolism

Question 7

Organisms possess specialized proteins that break
down food molecules. The organisms use the
nutrients from the food (source of energy) and raw
materials to synthesize new molecules. Energy is
used to rearrange the shape of molecules (shape
determines function). (TRUE OR FALSE)

Answer 7

True

Question 8

Some changes in molecular shape cannot allow certain
cells to change shape.
(TRUE OR FALSE)

Answer 8

False (Correct Answer: Some changes in molecular shape can allow certain
cells to change shape.)

Question 9

Specialized white blood cells can surround
and engulf potentially dangerous foreign invaders,
such as certain bacteria. (TRUE OR FALSE)

Answer 9

True

Question 10

This is necessary for responsiveness, growth,

development and reproduction.

Answer 10

Metabolism

Question 11

What are the 2 types of metabolism?

Answer 11

Anabolism & Catabolism

Question 12

It means “break down;”

e.g., cellular respiration

Answer 12

Catabolism

Question 13

It means “build up;” e.g, protein synthesis

Answer 13

Anabolism

Question 14

It is the organism’s ability to sense changes in its external
or internal environment and adjust to those
changes.

Answer 14

Responsiveness

Question 15

Actions include moving toward food or water and
moving away from danger or poor environmental
conditions.

Answer 15

Responsiveness

Question 16

Through responsiveness, organisms can also make adjustments that maintain
their internal environment (TRUE OR FALSE)

Answer 16

True

Question 17

If the external environment causes the
body temperature to ____, sweat glands will
produce sweat which ____ body temperature
down to normal range.

Answer 17

rise; lower

Question 18

It is an increase in size or number of cells, which produces

an overall enlargement of all or part of an organism.

Answer 18

Growth

Question 19

Muscle enlarged by exercise is composed
of larger muscle cells than those of an untrained
muscle, the skin of an adult has more cells than the
skin of an infant. (TRUE OR FALSE)

Answer 19

True

Question 20

Decrease in materials surrounding the cells contribute

to growth. (TRUE OR FALSE)

Answer 20

False (Correct Answer: INCREASE in materials surrounding the cells contribute
to growth.)

Question 21

Bones grow because of cell number
increase and deposition of mineralized materials
around the cell. (TRUE OR FALSE)

Answer 21

True

Question 22

What are the two types of growth?

Answer 22

Hypertrophy and hyperplasia

Question 23

It is an increase in size of cells wherein body mass increases

Answer 23

Hypertrophy

Question 24

It is an increase in number of cells

Answer 24

Hyperplasia

Question 25

Usually in a very young age, the body is actively
increasing in the number of adipocytes (fat tissues),
referring to hyperplasia; Then, if the amount of fat is not reduced as a child
grows, it is possible that the accumulated adipocytes
will grow in size, referring to hypertrophy. (TRUE OR FALSE)

Answer 25

True

Question 26

Changes in an organism undergoes through time,

beginning with fertilization and ending at death.

Answer 26

Development

Question 27

The
greatest developmental changes occur before
birth, but many changes continue after birth, and
some go on throughout life.
(TRUE OR FALSE)

Answer 27

True

Question 28

This usually involves growth but also involves

differentiation and morphogenesis.

Answer 28

Development

Question 29

It involves changes in a cell's structures and
function from an immune, generalized state to
a mature, specialized state.

Answer 29

Differentiation

Question 30

It is the change in shape of tissues, organs, and

the entire organism.

Answer 30

Morphogenesis

Question 31

It is called the formation of new cells or new organisms.

Answer 31

Reproduction

Question 32

Reproduction of cells allows for growth and

development. (TRUE OR FALSE0

Answer 32

True

Question 33

All living organisms pass on their genes to their

offspring. (TRUE OR FALSE)

Answer 33

True
