2. Cluster of atoms
3. Specialized part of a cell bound in a membrane; "little organ"
4. Smallest unit of living matter
5. Group of similar cells; makes up an organ
6. Structure containing two or more tissues
7. A group of organs

9. Collection of particular species in particular area
10. Collection of all species in particular area
11. Combined physical and biological components of an area
12. The surface and atmosphere of earth |
|
|
Term
| Can an organism have organs but not tissues? |
|
Definition
| No, because organs are a collection of tissues joined together. |
|
|
Term
| Distinguish between 1.producers, 2.consumers, and 3.decomposers. |
|
Definition
1. provide food for the ecosystem (trees, plants)
2. eat plants and other animals (humans, animals)
3. decompose waste and dead animal remains (bacteria, fungi, small animals) |
|
|
Term
| How does each of these groups interact with each other? |
|
Definition
| Photosynthetic organisms release oxygen into the air and animals take in oxygen and convert it into carbon dioxide. Decomposers recycle matter into minerals that plants can use. |
|
|
Term
| How does energy move through an ecosystem? How does energy enter a system? Exit? |
|
Definition
| Plants absorb energy from light and convert it into energy of sugars, etc. Consumers ingest it and it is passed to decomposers. It is converted to heat and exits. |
|
|
Term
| How does the photosynthesis of plants function in both the cycling of chemical nutrients and the flow of energy in an ecosystem? |
|
Definition
1. Animals absorb oxygen and release it as carbon dioxide
2. Plants convert chemicals into sugar and animals ingest it |
|
|
Term
| _____________is the lowest level of structure that can perform all activities required for life. |
|
Definition
|
|
Term
| What is meant by “emergent properties” as we discuss cell structure and function within an organism? |
|
Definition
| "The whole is greater than the sum of it's parts." A cell's structure can let us know what it's function is. |
|
|
Term
| Distinguish between prokaryotic and eukaryotic cells. |
|
Definition
Pro-unicellular, usually smaller, lacks membrane enclosed organelles, Bacteria/Archea
Euka-Organelles divided by membranes; everything but Bacteria/Archea |
|
|
Term
| Name the seven characteristics of life. |
|
Definition
| Order, regulation, growth/development, energy processing, response to environment, reproduction, and evolutionary adaptation. |
|
|
Term
| What is the chemical basis for the unity of life? |
|
Definition
| Chains of DNA molecules are chemical "building blocks." DNA accounts for the unity AND diversity of life. |
|
|
Term
|
Definition
| Branch of biology that identifies, names and classifies species. |
|
|
Term
| What is a domain? Name the three recognized domains and the group of organisms found in each. |
|
Definition
| Taxonomic category above Kingdom. Three domains are Bacteria, Archea, and Eukarya. |
|
|
Term
| Name the four kingdoms found in the Domain Eukarya. For each, give a brief description of the types of organisms found in the kingdom and their method of obtaining food. |
|
Definition
Protists-mostly single celled, eat by photosynthesis or eat other organisms
(all others are multicellular)
Fungi-Molds, yeasts, mushrooms (mostly decomposers). Ingest dead organisms & wastes.
Plante-Consists of plants, make food by photosynthesis.
Animalia-mostly motile, cells lack cellulose, eat other organisms. |
|
|
Term
| Prokaryotes are found in the Domains ___________and _____________. |
|
Definition
|
|
Term
| Eukaryotes are found in the Domain_____________. |
|
Definition
|
|
Term
| What two points did Charles Darwin propose in his book, The Origin of Species? |
|
Definition
1. Evidence to support the theory of evolution
2. Evidence for natural selection to support his theory of evolution |
|
|
Term
| What observations did Darwin make that led him to believe that natural selection was the mechanism for evolution? |
|
Definition
1. Individuals' heritable traits vary
2. Species have the ability to produce more offspring than will survive
3. Individuals with desirable traits will leave most offspring
4. Over time, higher number will have those desirable traits |
|
|
Term
| What is evolutionary adaptation? |
|
Definition
| An organism adapting to its' natural environment over time by evolutionary means. |
|
|
Term
| Give an example of natural selection. |
|
Definition
antibiotic resistance in microorganisms.

|
|
Term
| How does natural selection enable a population of organisms to adapt to their environment? |
|
Definition
| Organisms who receive better genes are better able to survive in their environment; obtain food, communicate within their species, get a mate and pass on their good genes, and shelter themselves from the environment. |
|
|
Term
| Distinguish between hypothesis-based science and discovery science. |
|
Definition
-uses data from discovery science for explanations (tests hypotheses)
-uses verifiable observations and measurements to obtain data |
|
|
Term
| Distinguish between a theory and a hypothesis. |
|
Definition
-supported by some amount of evidence
-explanation for a set of reasons |
|
|
Term
| What is the purpose of a controlled experiment? |
|
Definition
| There must be a control group to compare to the experimental group. |
|
|
Term
| How are science and technology related? |
|
Definition
| Science seeks understanding of natural phenomena, but technology is the application of science to our lives. |
