Flashcards in Intro To Living Things Deck (23):
1

Organism

If you were to asked to name some living things, or organisms, you might name yourself, a pet and some insects or plants.

2

Cell

A cell is the basic unit of structure and function in a organism.

3

Unicellular

Single called organisms, like bacteria are unicellular organisms.

4

Multicellular

Organisms that are composed of many cells are multicellular.

5

Metabolism

The combination of chemical reactions through which an orgnisum builds up or breaks down material is called metabolism

6

Stimulus

A chained in an organisms surroundings that causes the organism to react is called a stimulus

7

Response

An organism reacts to a stimulus with a response-an action or a change in behavior.

8

Development

Development is the process of change that occurs during an organisms life.

9

Asexual reproduction

Asexual reproduction involves only one parent and produces offspring that are identical to the parent

10

Sexual reproduction

Sexual reproduction involves two parents and combines their genetic material to produce anew organism that differs form the parents.

11

Spontaneous generation

The mistakes idea that living things arise form non living sources is called spontaneous generation

12

Controlled experiment

In a controlled experiment, a scientist carries out a series of tests that are identical in every aspect except for one another.

13

Autotrophs

Organisms that make their own food are called autotrophs

14

Heterotrophs

Orgisims that cannot make their own food are called heterotrophs.

15

Homeostasis

The maintenance of stable inheritance conditions is called homeostasis.

16

Classification

Classification is the process of grouping things based on their similarities.

17

Taxonomy

The scientific study of how organisms are classified are called taxonomy

18

binomial nomenclature

Binomial means two names

19

genus

A genus is a classification grouping that contagion similarities closely related organisms

20

Species

A species is a group of similar organisms that can produce offspring that can also produce.

21

Prokaryotes

Prokaryotes are unicellular organisms whose cells lack a nucleus.

22

Nucleus

A nucleus is a dense area in the cell that contains nucleic acids-the chemical instructors that direct the cell’s activity’s

23

Eukaryotes

Organisms in this domain are eukaryotes- organisms with cells that contain nuclei.
