- Distinguish between living and non-living things based on the principal features/characteristics of life. Answer-Living things display all of these characteristics: they reproduce and grow, use energy, have levels of organization, maintain constant internal conditions, and evolve.
- Describe the relationship among atoms, macromolecules, and cells.Answer- Atoms build up to make macromolecules then marcromolecules build up to make cells.
- Describe cellular structures and functions in eukaryotic cells. Answer- A cell is defined as eukaryotic if it has a membrane-bound nucleus.
- Compare the structure and function of eukaryotic cells vs. prokaryotic cells. Answer-The distinction between prokaryotes and eukaryotes is considered to be the most important distinction among groups of organisms. Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA.(Citation-"Eukaryotic Cell vs Prokaryotic Cell." - Difference and Comparison. N.p., n.d. Web. 26 Apr. 2014.)
- Explain the importance of enzymes to cellular function.Answer- Enzymes are proteins that control the speed of chemical reactions in your body. Without enzymes, these reactions would take place too slowly to keep you alive. Some enzymes, like the ones in your gut, break down large molecules into smaller ones. Others, like the enzymes that make DNA, use small molecules to build up large complex ones. Enzymes also help cells to communicate with each other, keeping cell growth, life and death under control.(Citation-"Who Am I?" Why Are Enzymes Important? N.p., n.d. Web. 24 Apr. 2014.)
- Explain the steps and importance of cell division.Answer- Cell division is important because it helps cells to produce new cells. Cell division is a process in which, a large cell called the mother cell splits into two parts and each of the parts are called daughter cells.
- Describe the relationship between cell division and cancer.Answer- When a cancerous cell goes through mitosis it does so much more rapidly than regular cell division.
- Explain the overall process and importance of meiosis. Answer- Meiosis increases the genetic variation, such that there are two divisions meaning four haploids with different sets of chromosomes each. Meiosis is a process of cell division in which gametes are produced. Meiosis reduces the diploid cells to haploid cells or gametes.
- Describe and construct the structure of DNA. Answer- DNA: A nucleic acid that carries the genetic information in the cell and is capable of self-replication and synthesis of RNA. DNA consists of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. The sequence of nucleotides determines individual hereditary characteristics.(Citation-"DNA+structure." The Free Dictionary. Farlex, n.d. Web. 26 Apr. 2014.)
- Describe the relationship among DNA, genes, and alleles.Answer- Genes are what show up / code for something. these are on the chromosomes. There are two alleles that each of us have that control what the genes are doing (i.e. brown hair / blond hair). and DNA is the sequence of nucleotide bases which code for genes.
- Explain how genes are inherited in sexual and asexual reproduction. Answer- With sexual reproduction the offspring will share the genetic material from both it's mother and father. With asexual the single species can fertilize and produce an identical offspring with the same genetic material

Stages of cell division
onion root tip+Task- Locate and identify the principle stages of mitosis on slides of plant and animal tissue, diagram and label the principle stages of plant and animal mitosis, explain what is happening during each stage of mitosis, identify interphase and cytokineses, and describe how cytokineses differs between plant and animal cells.
