Life Sciences – Cell Biology: Section E in textbook



Life Sciences – Cell Biology: Section E in textbook

1) List the 4 characteristics of living things.

2) What is the difference between a unicellular and multicellular organism? What about the difference between a eukaryotic cell and a prokaryotic cell? Which usually goes with which?

3) Complete the chart with each of the 9 organelles (nucleus, cell membrane, vacuole, lysosome, mitochondria, cytoplasm, endoplasmic reticulum, golgi body, ribosome).

|Name of Organelle |Function of Organelle |

|Example: Nucleus |Controls the cell and contains its genetic |

| |material (DNA) |

4) Advanced cellular processes can be referred to as STERNGRR – identify the process each letter represents as well as an example of each of these processes

5) Use the gummy bear demonstration to explain what osmosis, diffusion, equilibrium & concentration are.

6) What is a pathogen?

Copy and complete the chart on the top of the next page for the 4 types of pathogens.

|Pathogen: |Characteristics: |Diseases it causes: | |

| | |(at least 2 examples!) |Treatment |

|Fungi | | | |

|Virus | | | |

|Bacteria | | | |

|Parasite | | | |

7) What does it mean when pathogens are referred to as contagions? What about mutagens?

8) What is the difference between a vector and a carrier?

9) What is the difference between an epidemic & pandemic?

• Can you give an example of each from any point in history?

10) List 3 examples and 3 careers associated with the field of biotechnology.

Life Sciences – Ecology: Section B in textbook

Choose a specific ecosystem to focus on (example: rainforest, ocean, etc) and answer all of the following questions with that ecosystem in mind:

1) Draw an energy pyramid:

• Label or list producers, primary consumers, secondary consumers, tertiary consumers.

• Label where the most energy vs. the least energy is found based on the “Rule of 10”

2) Provide examples of the following within your ecosystem:

Biotic factor-

Abiotic factor-

Autotroph-

Heterotroph-

Population-

Niche of a specific organism-

Density-dependent limiting factor-

Density-independent limiting factor-

Predator/prey relationship-

Cooperation-

Competition-

Parasitism-

Mutualism-

Commensalism-

Example of a connection between an aquatic & terrestrial food chain-

3) How does energy move through an ecosystem vs. how matter moves through an ecosystem?

4) Draw and label the steps of the nitrogen cycle.

5) Draw and label the steps of the carbon cycle.
