• Identify what all living things need to survive

What Are the Characteristics All Living Things Share?

Let's find out some of these characteristics. Read page 5 to 7. Underline the main ideas.

All Living Things

• have cellular organization (unicellular or multicellular)

• contain similar chemicals (the most abundant one: water, but also carbohydrates and nucleic acids)

• use energy (they do it in a combination of chemical reactions called metabolism)

• respond to their surroundings (in two steps: stimulus (change in the surroundings) and response (action or change in the behavior))

• grow (become larger) and develop (become complex during the organism's life)

• reproduce (living things reproduce sexually (which involves 2 parents and a combination in the DNA) and asexually (which involves one parent that produces identical offspring)

Multiple Choice

Asexual Reproduction

• A reproductive process that involves only one parent and produces offsprings that are genetically identical to the parent.

• Any change or signal in the environment that can make an organism react in some way.

• A reproductive process that involves two parents that combine their genetic material to produce a new organism which is different from both of their parents.

• A living thing.

Multiple Choice

Development

• A living thng.

• Made of many cells.

• Any change or signal in the environment that can make an organism react in some way.

• The process of change that occurs during an organism's life to produce a more complex organism.

Multiple Choice

Response

• An action or change in behavior that occurs as a result of stimulus.

Multiple Choice

Stimulus

• An action or change in behavior that occurs as a result of a stimulus.

• The process of change that occurs during an organism's life to produce a more complex organism.
