Science Characteristics of Life

Question 1

How do you know something is living?
It must demonstrate all

Answer 1

of the characteristics of life

Question 2

Organization define

Answer 2

These levels has specific structures and functions that work together to keep the living thing alive.

Question 3

Growth and Development define

Answer 3

Living things growth, which involves an increase in size or number of cells, and development, which involves changes in their structure and function over time.

Question 4

Reproduction define

Answer 4

Living things are capable of producing offspring through reproduction.

Question 5

Responses to Stimuli define

Answer 5

Living things can sense and respond to changes in their environment or stimuli, both internal and external. This includes things like responding to changes in temperature, light, or sound, as well as responding to internal stimuli like hunger or thirst.

Question 6

Homeostasis define

Answer 6

Living things are able to maintain a stable internal environment despite changes in their external environment or the demands on their cells. This can include things like regulating body temperature, and blood sugar levels.

Question 7

Use of Energy define

Answer 7

Living things require energy to carry out their life processes or activities. They obtain energy from food or sunlight and use it to carry out various processes like growth, movement, and reproduction.

Question 8

Cell membrane what are the parts of the cell and the functions they perform?

Answer 8

This is like a gatekeeper that surrounds the cell and controls what goes in and out of the cell.

Question 9

Cell wall what are the parts of the cell and the functions they perform?

Answer 9

This is like a protective layer around the cell that gives it shape and support. It’s only found in plant, fungal, and bacterial cells.

Question 10

Cytoplasm what are the parts of the cell and the functions they perform?

Answer 10

This is like a jelly that fills the cell and contains all the cell’s parts. It’s where many of the cell’s processes happen.

Question 11

Nucleus what are the parts of the cell and the functions they perform?

Answer 11

This is like the control center of the cell. It contains the DNA that tells the cell what to do and when to do it.

Question 12

Chloroplast what are the parts of the cell and the functions they perform?

Answer 12

This is like a solar panel that’s only found in plant cells. It helps the plant make food using energy from the sun.

Question 13

Mitochondria what are the parts of the cell and the functions they perform?

Answer 13

These are like the powerhouses of the cell. They turn food into energy that the cell can use.

Question 14

Vacuole what are the parts of the cell and the functions they perform?

Answer 14

This is like a storage container for the cell. It stores water, food, and waste products, and helps keep the cell’s shape and structure.

Question 15

Name the six characteristics of all life

Answer 15

1. Organization
2. Growth and development
3. Reproduction
4. Response to stimuli
5. Homeostasis
6. Use of energy

Question 16

Explain why movement is not considered a characteristic of life

Answer 16

Movement is not considered a characteristic of life because there are things that can move but are not alive. For example, a car or a rock can move, but they are not considered to be alive.
