Life Science MCA Power Point Review

**RESEARCH: With your partner, do the necessary research to complete the topic you were assigned & fill in your topic's slide.

**PICTURE: Every topic needs at least ONEpicture that explains your topic & any other questions asked for.

**PRESENT: Be ready to do a SHORT presentation of your slide at the end of the class--both partners need to present.

Topic #2: Cells--What is the difference between...

• Plant Cells

• Animal Cells

7.4.1.2-All living organisms are made of 1+ cells which carry on the many functions needed to live.

Topic #2.5: Cells

• How do cells make more cells?

• What is the purpose of cells?

7.4.2.1.1-ID a variety of populations and communities in an ecosystem and how they are related.

Topic #3--Ecosystems

● Explain the difference between populations& communities?

● Show a picture of an ecosystem and labelthe populations & communities present.

7.4.2.1.2-Compare and contrast the roles of the following: predator vs. prey, parasite vs. host

Topic #4--Organism Interactions

What is the difference between a …

• Predator vs. Prey

• Parasite vs. Host

7.4.2.1.2-Compare and contrast the roles of the following: producer, consumer, decomposer.

Topic #5--Organism Interactions

What is the difference between a…

• producer-• consumer-• decomposer-

*Show a cycle that illustrates how these are allrelated to each other in a specific example

7.4.2.1.3--The number of populations that are supported in an ecosystem depend on the biotic resources available and the abiotic factors

Topic #6: Populations

What are…

● Biotic Resources:

○ examples:

● Abiotic Factors:

○ examples:

7.4.2.2.1-Producers use the energy from the Sun to make sugars from CO2 and H20 by photosynthesis. This food can be used, stored later, or used by other organisms.

Topic #7: Photosynthesis

Explain what goes on in Photosynthesis.

7.4.2.2.2&3-Describe the roles & relationships among producers, consumers & decomposers in changing energy from 1 form to another in a food web. The total amount of matter in an ecosystem stays the same, it's just transferred from 1 location to another.

Topic #8: Food Webs

What is a food web?

**Find a picture or two that show how food webs show the relationships between organisms in an ecosystem. Label the producers, consumers anddecomposers in the diagram.

7.4.3.1.1--Reproduction allows for the continuation of a species. Hereditary information is contained in genes which are inherited through asexual & sexual reproduction.

Topic #9: Genetics & Reproduction

●What is Heredity?

●What are genes and where are they found?

●What is the difference between asexual and sexual reproduction at a cellular level?

7.4.3.2-Individual organisms with certain traits in particular environments are more likely than others to survive & have offspring.

Topic #10--Survival

● What is extinction?

● How might animals or plants adapt to survivein a specific or changing environment?

● Explain how the finches adapted on theGalapagos islands?

7.4.4.1-Human activity can change the ecosystem

Topic #11--Human activity Ecosystem Change

What is Selective Breeding?

(Give examples of how selective breeding=new varieties of plants and animals)

What are ways humans can change a population or ecosystem?

7.4.4.2.1: Explain how viruses, bacteria, fungi and parasites may infect the human body and cause problems.

Topic #12--Viruses & Bacteria

What is the difference between a …

• Virus

• Bacteria

*Explain the differences in how viruses and bacteria infect the body and cause problems.*Which one (viruses or bacteria) can be effectively treated with antibiotics?

7.4.4.2.3--Recognize that vaccines cause the body to build immunity to a disease without actually causing the disease itself.

Topic #13--Vaccines

What is a vaccine?

How do vaccines work?

7.4.4.2.4-Our immune system protects us against microscopic organisms and foreign substances that enterfrom outside and against some cancer cells that arise from within the body

Topic #14 -Immune System

Explain how our immune system works and fights offforeign substances:
