Cells: Similarities Plant Animal Cell Membrane Cytoplasm Nucleus Mitochondria Organelles: Small , membrane enclosed, parts of the cell that do a specific job.
Cells: Differences Animal Plant Cell Wall Vacuole Chloroplasts Organelles: Small , membrane enclosed, parts of the cell that do a specific job.
Cells Questions: 1. What type of cells are these? 2. How can you tell? 3. What is the importance of the green organelles?
Types of Cells There are many different types of cells. Different cells can look very different. Red Blood Cells Neurons: Brain Cells Cardiac Muscle Cells Their shape and size help them do their specific job.

DNA, Genes, and Heredity
DNA, Genes, and Heredity
DNA, Genes, and Heredity This is a Karyotype. It shows the 23 PAIRS of chromosomes in one human skin cell. These chromosomes contain DNA. 23 individual chromosomes came from the mother and 23 of them came from the father. Can you tell if this DNA came from a boy or a Girl? It’s a BOY! XY is a boy and XX is a girl
Punnett Square for Gender
Punnett Squares
Genotype and Phenotype Genotype: the genes passed down from the parents Phenotype: the trait that you can see
Punnett Squares What percentage of the offspring will have yellow Seeds? Green Seeds?

Sexual vs. Asexual Reproduction Sexual Reproduction: – 2 Parents – Offspring are NOT identical to the parents • More genetic diversity Asexual Reproduction: – 1 Parents – Offspring are identical to the parent
Sexual vs. Asexual Reproduction Question: Which type of reproduction will lead to greater genetic diversity in a population?
Food Chain • All organisms in an ecosystem • Arrows go in the direction of Energy flow • Producers (Plants) convert solar energy into food for all other organisms to use
Food Chain: Trophic Levels Feeder Level Plants PRODUCE their own food Primary (First) Consumers Eat ONLY Plants - Herbivores Secondary Consumers Eat Primary Consumers Tertiary Consumers Eat Secondary Consumers Top Predators - Carnivores
Food Web • The interactions of all organisms in an ecosystem • Arrows go in the direction of Energy flow • Producers (Plants) convert solar energy into food for all other organisms to use http: //www. youtube. com/watch? v=Ed. Kh. QVHc 3 Ao
Symbiosis Relationships between Organisms Mutualism Parasitism Commensalism Predator -Prey
Evolution By Natural Selection Natural selection is simply the logical result of four features of living systems: variation - individuals in a population vary from one another inheritance - parents pass on their traits to their offspring genetically selection - some variants reproduce more than others time - successful variations accumulate over many generations http: //www. nhm. ac. uk/natureonline/evolution/what-is-evolution/naturalselection-game/the-evolution-experience. html http: //www. techapps. net/interactives/pepper Moths. swf
