Big Idea 3 #1-10


1. Big Idea 3: Eukaryotes
     Eukaryotes are simply multicellular organisms. The picture shown depicts a duck, which is a prime example of a eukaryote, as they consist of millions of cells. This picture relates to big idea three by showing how, though made of millions of cells, each cell is able to store, transmit, and receive data necessary to make a working animal.

2. Big Idea 3: Phenotype
     The phenotype of a plant or animal is the physical appearance that results from specific alleles and genes. This picture shows phenotype by showing a plant that has red berries, while other plants have black, or blue berries. The picture relates to big idea three by showing that all living systems transmit different messages to their offspring through their DNA.

3. Big Idea 3: Seed Dispersal Method
     Seed dispersal method is the method that a plant uses to spread its seeds; they include wind, water, animal, and gravity. This picture shows a plant that uses gravity at first, as the container falls to the ground, and then, once it opens, uses wind to transport the seeds. It relates to big idea three by showing how "living systems" use information to learn the best way to reproduce, an "essential life process."

4. Big Idea 3: Behavior
     Behavior is the actions displayed an organism in response to its environment. This picture demonstrates behavior, as the bamboo cannot grow directly up, so it modifies its behavior to grow around the stick in the center. The picture demonstrates big idea three by showing that organisms can respond intelligently based on the data they have received and stored.

5. Big Idea 3: Genetically Modified Organism
     A genetically modified organism is any organism that has been genetically altered to express a trait that humanity wanted. This picture shows rice, which has often been altered to express increased resistance to insects and increased amounts of nutrients. This relates to big idea three by showing that organisms respond directly to their offspring by DNA, which can be altered by humans.

6. Big Idea 3: Tropism
     Tropism is the movement of a plant towards an environmental stimulus, such as light. This picture shows tropism, as the plant demonstrates a curve towards the light. This relates to big idea three by showing that plants are intelligent enough to receive information about where they are receiving light from and then act on that information.

7. Big Idea 3: Herbivory Responses
     Herbivory responses are both the actions of the plants the herbivores eat and the herbivores themselves; both seek to gain an increased advantage. This picture shows molars, which herbivores developed so as to be able to fully grind down and digest their food. This picture relates to big idea three by showing that organisms are able to respond directly to resolve problems in a diet.

8. Big Idea 3: Ethylene
     Ethylene is a plant hormone which is associated with the ripening of fruit and fruit abscission. This picture shows the results of the hormone by showing the fruit of various plants. This picture relates to big idea three by showing that plants have the ability to sense not only what to do but also when to do it.

9. Big Idea 3: Diploid
     Diploid cells are cells that possess two sets of chromosomes and undergo constant mitosis. This picture shows skin cells, which are some of the many types of diploid cells in our body. The picture relates to big idea three because it shows that organism have the ability to know when and where to replicate cells, as skin cells constantly need to replicate.

10. Big Idea 3: Two Alleles for the Same Trait
     Two alleles for the same trait usually results when two dominant or two recessive alleles code for the same thing. In this case, the person has a flat hairline, when his father has a widow's peak, meaning this person has two recessive alleles for a flat hairline. This relates to big idea three by showing that animals are able to not only receive data, but also put it into use as well.
