Can someone help me fill out this study guide?
Unit 2: Cells, DNA and Cell Division. Cells will be introduced. This unit will also include how energy is transferred through living things. Unit II will develop the concept of genetic material (DNA) and its importance in mitotic cell division. Chapters 4, 5, 6, 7, 8, 11
Outcome 3. Compare the cellular components of life.
List the key concepts of the cell theory. (pages. 68-69, lecture)
Distinguish between the characteristics of prokaryotic cells and eukaryotic cells. Explain how viruses fit into this plan. (pages. 69-73, 308 lecture)
Know the function of the following cell structures: nucleus, cytoplasm, nucleolus, ribosomes, smooth and rough endoplasmic reticulum, Golgi complex, mitochondria, cell wall, chloroplast. (pages. 72-83)
Describe how materials are transported actively or passively into or out of a cell. Terms: plasma membrane, diffusion, osmosis, isotonic, hypotonic, hypertonic, active transport, passive transport, endocytosis, exocytosis. (pages. 74–75, 84–90)
Define ATP and identify how it functions as an energy carrier. (pages. 100-101)
Recognize the overall energy pathway and how energy moves through living things. Terms: photosynthesis, aerobic respiration, anaerobic respiration, glycolysis, Krebs cycle, electron transport. (pages. 106–114, 116, 119–130, 132 and lecture)
Describe the structure of nucleic acids. List and explain the series of experiments that led to the discovery that DNA is the genetic material. Identify how the scientific method was involved in these discoveries. Terms: DNA, RNA, ribose, deoxyribose, nucleotide, phosphate, nitrogen base, adenine, guanine, thymine, cytosine, uracil, double helix, nuclein, Hershey-Chase, Griffith, Avery, Watson, Crick, Franklin, Chargaff, Wilkins. (pages. 190–196, 202 and lecture)
Describe DNA replication. Terms: DNA polymerase, helicase, leading strand, lagging strand. (pages. 194-197, 202,)
Outcome 4. Identify the processes of somatic cell division.
Recognize what happens when DNA condenses to form chromosomes. Identify the parts of a chromosome. Terms: sister chromatids, centromere. (pages. 138-139)
Describe the cell cycle. Identify what happens during interphase. Terms: G1, S, G2, M and C. (pages. 136-137)
List the stages of mitosis and what happens during each stage. Terms: prophase, metaphase, anaphase, telophase, centrioles, spindle fibers. (pages. 140-141)
Define cytokinesis and distinguish the differences in cytokinesis between plant and animal cells. Terms: cleavage furrow, cell plate. (page.142)
Explanation / Answer
Answer=
Key concepts of cell theory are as follows:
1.Cells are the units of structure (building blocks ) of all animals and plants.
2.Cells are the smallest unit of function in all animals & plants.
3.Cells originate only from pre-existing cells by cell division.
4.All cells maintain homeostasis.
