1

Biology is..

The study of life

2

Biologists..

make discoveries and seek explanations performing laboratory field investigations

3

Biologists study the diversity of..

Life (Jane Goodall studied chimpanzees in their natural habitat)

4

Biologists research...

diseases(Mary-Claire King studied chimpanzee genetics and found humans are 99% identical to chimpanzees)

5

Biologists develop

technologies(Dr.Charles Drew did research that led to storage blood for transfusions)

6

Biologists improve..

Agriculture(Joanne Chory helped agriculturists to increase food produced from cops)

7

Biologists preserve...

The environment(Lee Anne Martinez developed waterless composting toilets for people in Africa to use composted waste to improve soil for agricultural use.)

8

Characteristics shared by all living organisms include:

Made of 1 or more cells, displays organization, grows and develops, reproduces, responds to stimuli, requires energy, maintains homeostasis. adaptions evolve over time.

9

Cells are..

the basic unit of structure and function in living things.

10

Cells can vary in size, but

the basic structure of cells is the same in all organisms, some are more complex.

11

Living things are..

arranged in an orderly way

12

Examples of orderly living things:

Paramecium is unicellular, yet is a collection of organized structures that carry on life functions. Multicellular organisms have specialized cells organized into groups that work together.

13

22

Organisms internal environment is..

all things inside it

23

Stimulus:

part of environment that causes a reaction

24

Response:

reaction to stimulus

25

All things living use energy for

life processes

26

How energy flows:

sun-plants-plant eaters-meat eaters

27

Homeostasis:

Maintaining constant internal conditions despite environmental changes

28

Examples of homeostasis:

temperature, disease, sickness

29

Adaption:

change in an organism to survive
