Flashcards in Life Characteristics Deck (22):
1

What are all the characteristics of life

Cells
Organization
Growth/development
Reproduction
Responses to stimuli
Requires energy
Maintains homeostasis
Adaptation

2

Cells definition

Basic component of all living things

3

One cell

Unicellular

4

Many cells

Multicellular

5

Organization of what makes up what

Cells make up tissues
Tissues make up organs
Organs make up systems
Systems carry out bodily functions

6

Definition of growth

Increase in mass to an organism, and in many organisms, the formation of new cells and structures

7

Reproduction definition

Production of offspring which must occur in order for species to continue

8

Species definition

A group of organisms that can mate with one another to produce FERTILE offspring

9

Stimulus

A signal to which an organism reacts

10

Response

Reaction to stimuli

11

What is energy used for

Carrying out essential biological procedures

12

Autotrophic

Produces own food (light or chemicals

13

Heterotrophic

Consumes food

14

Decomposer

Breaks down dead materials for food

15

Maintains homeostasis

Constant maintenance of an organisms internal environment

16

Homeostasis

When a change in the internal environment occurs, processes within the organism work to regain the normal environment state

17

Adaptation

Any inherited characteristics that result from changes to a species over time. These characteristics are favorable for species and allows them to pass their genes to their offspring

18

Animals panting

Homeostasis

19

When you get a temp and your body cools down

Homeostasis

20

Growing more hair

Adaptation

21

Putting on a coat

Response

22
