CHARACTERISTICS OF LIVING THINGS

CHARACTERISTICS OF LIVING THINGS

• The six characteristics of living things are:

• Living things must have cells

• Living things must sense and respond to change

• Living things must be able to reproduce

• Living things must be able to reproduce

• Living things must have DNA

• Living things must use energy

• Living things must grow and develop

Living things must have cells

Living things must have cells

• Every living organism is composed of cells.

• A cell is a membrane-covered structure that contains al of the materials necessary for life

• There are two types of cells:– Unicellular– Multicellular

• Every living organism is composed of cells.

• A cell is a membrane-covered structure that contains al of the materials necessary for life

• There are two types of cells:– Unicellular– Multicellular

Characteristics of Unicelluar organisms

Characteristics of Unicelluar organisms

Unicellular organism are composed of

only one cell

Examples:

Protista

Monera

Bacteria

Unicellular organism are composed of

only one cell

Examples:

Protista

Monera

Bacteria

Characteristics of Multicellular organisms

Characteristics of Multicellular organisms

• Multicellular organisms are composed of

two or more cells and the

numbers can be in the trillions.

Examples:

Plantae

animalia

• Multicellular organisms are composed of

two or more cells and the

numbers can be in the trillions.

Examples:

Plantae

animalia

• Multicellular organisms has cells that perform specific functions.

Examples: Muscle cells are specialized for movement

Nerve cells transport signals

• Multicellular organisms has cells that perform specific functions.

Examples: Muscle cells are specialized for movement

Nerve cells transport signals

Living things must sense and respond to

change

Living things must sense and respond to

changeAll organisms have the ability to sense

change in their environment and respond to that change.

Stimulus (plural stimuli) is any

change in an organism’s

environment that affects

the activity of the organism

All organisms have the ability to sense change in their environment and respond to that change.

Stimulus (plural stimuli) is any

change in an organism’s

environment that affects

the activity of the organism

Response is the reaction to what

happens when you reacted

to the stimulus

Response is the reaction to what

happens when you reacted

to the stimulus

• Homeostasis is the ability to maintain a stable internal environment regardless of the external environment

Example: - The body sweats when it is hot outside in the summer - The body shivers with cold chills when the body is cold

• Homeostasis is the ability to maintain a stable internal environment regardless of the external environment

Example: - The body sweats when it is hot outside in the summer - The body shivers with cold chills when the body is cold

Living must be able to reproduce

Living must be able to reproduce

• There are two types of reproduction:– Asexual– Sexual

• There are two types of reproduction:– Asexual– Sexual

Living things must have DNA

Living things must have DNA

• DNA is an acronym for deoxyribonucleic

acid

Deoxyribonucleic acid is heredity material

that controls all the activities of

a cell, contains the information

to make new cells

and provides for

making proteins

• DNA is an acronym for deoxyribonucleic

acid

Deoxyribonucleic acid is heredity material

that controls all the activities of

a cell, contains the information

to make new cells

and provides for

making proteins

• DNA provides instructions for making molecules called proteins

• Proteins are responsible for almost all of the

activities of an organism’s

characteristics

• DNA provides instructions for making molecules called proteins

• Proteins are responsible for almost all of the

activities of an organism’s

characteristics

• During reproduction DNA is copied and passed on its offspring

• DNA carries the characteristics of the organism

• Heredity is the transmission of characteristics from one generation to the next generation

• During reproduction DNA is copied and passed on its offspring

• DNA carries the characteristics of the organism

• Heredity is the transmission of characteristics from one generation to the next generation

Living things must use Energy

Living things must use Energy

• Organisms use energy to carry out the activities of life

• Organisms use energy to carry out the activities of life

Living things must have the ability to Grow and

Develop

Living things must have the ability to Grow and

Develop• All organisms regardless whether

they are unicellular (single-cell) or

multicellular (two or more cells) grow and develop during periods of their lives

• All organisms regardless whether they are unicellular (single-cell) or

multicellular (two or more cells) grow and develop during periods of their lives
