This is what I learned about.........
Throughout this trimester I learned many things that I fully understand and could explain thoroughly. The properties of water: Cohesion and Adhesion, Temperature moderation, Low density of Ice, waters ability to dissolve other substances, and the PH scale all make sense to me. A carbohydrate is an organic compound made up of sugar molecules. A monosaccharide are simple sugar that contain one sugar unit. A disaccharide consists of a double sugar unit, and a polysaccharide are long polymer chains made up of simple sugar monomers. I learned the characteristics of Lipids which include fats and steroids, Proteins which perform most functions in cells, and enzymes and how they work. In chapter 6.1 i learned the three different types of microscopes: light, scanning, and transmission. A light shows the interior of the cell, its not very detailed, scanning shows cells surface, and transmission shows internal details of a preserved cell. I know the difference between an Animal and a plant cell. I also learned each organelle and their function in a cell, and how membranes regulate the traffic of molecules through active and passive transport. The cell cycle consists of interphase and mitotic phase. In the mitotic phase the cell divides within each step: prophase, metaphase, anaphase, and telophase/ cytokinesis. Meiosis instead of producing two cells, produces four. Also it has to do with the division of the sex cells.
What I have found difficult about what I have studied is.........
Im still fuzzy on the building and breaking polymers, I know the definition of a monomer and polymer but the process confuses me. Also Meiosis is still confusing to me, it makes sense that its the reproduction of the sex chromosomes and it produces a haploid, but the whole process put together confuses me. Also I don't understand how tetrads are produced. The difference between Homologous chromosomes and sister chromatids also tend to confuse me.
How is structure related to function?
Structure is related to function in so many ways... In the cell each organelle has a specific function and without that function the body wouldn't be able to carry out it's necessary routines. The structure in reproduction is crucial to the end result. Every step in mitosis and meiosis has it's own function in reproduction. In interphase DNA has duplicated and it consists of check points G1, S phase, and G2. Mitotic phase is where the division takes place in the process of Prophase, metaphase, anaphase, telophase and cytokinesis. Structure is key to the outcome result of it's function in both organelles and reproduction.
