Introduction to Living Things

2. Taxonomy is
The scientific study of how living things are classified.

3. When a plant grows toward light, the plant’s action is a response.

4. Classification Level
What is the broadest classification level?
DOMAIN

5. Which characteristic could be used to place organisms into kingdoms?
Their ability to make food

6. What does an organisms scientific name consist of?
Genus name & Species name

7. Which group contains only multicellular heterotrophs?
animals

8. Scientists get information about evolutionary history of species by:
comparing body structures

9. What is an organism that makes its own food called?
autotroph

10. Water is more abundant in living cells.

11. What happens when two organisms share many classification levels?
they have more characteristics in common

12. Redi and Pasteur helped demonstrate that:
Living things do not arise from nonliving materials.
Spontaneous generation is a mistaken idea because:
Living things are produced by other living things.

13. Which kingdoms include unicellular and multicellular organisms?
Fungi & Protists
Charles Darwin’s theory of evolution had a major impact on classification.

14. Gradual change in species over time is evolution.
Which domains include only prokaryotes?
Bacteria & Archaea

15. Each genus of organisms contain one or more species.
Archaea aren’t classified with bacteria because its chemical makeup is different.
An owl & robin share-kingdom, phylum, & class AND have more in common than an owl and bat.

16. Biologists find taxonomy useful because it gives them information about an organism based on classification.
Stable internal conditions held by an organism is homeostasis.

17. Genus is the first word in an organism’s scientific name.
Evolutionary history suggests bats and whales have similar characteristics.
A taxonomic key consists of paired statements about characteristics of organisms.
