Unit 3 Reflection

This unit contained information explaining the cell theory, which is the belief that all things are composed of cells, cells are the basic unit of life, and new cells are generated from existing cells. I also learned that prokaryotic cells have no nucleus, 1 chromosome, and circular DNA called plasmids. Eukaryotic cells have nucleus and long chains of DNA called chromosomes. 
I also learned that each macromolecule makes up a different part of the cell, serving a different purpose. For example: Carbohydrates make up call walls, help cells communicate , and they store energy. Proteins are catalytic building blocks that allow molecules in and out of the cell. Lipids make up plasma, and nucleotides hold information.
The Unit then explains osmosis which is the diffusion of water across a selectively permeable membrane. Tonic is the ability of a surrounding solution to cause a cell to gain or lose water. Cells change in response to different environmental conditions because of the typically small molecules- Turgor pressure exists inside the cell when the cell swell.
Photosynthesis is the process in which plants produce glucose and oxygen using sunlight and carbon dioxide. Plants grow best under red and blue light, and worst under green and yellow light.
Cellular respiration of process of cells breaking down glucose and energy. Both of these processes rely on each other.
An essential theme was understanding exactly what part of the cell performs what function. The understanding of parts of the cell is essential in this unit to completely understand photosynthesis and cellular respiration. This topic was thoroughly explained.

One of my weaknesses was keeping track of which process produced what product(s). I eventually figured out that glycolysis is the process in which one molecule of glucose is broken in half, producing two molecules of pyruvic acid, a 3-carbon compound. The Krebs cycle breaks down pyruvic acid into carbon dioxide in a series of energy-extracting reactions. I want to learn more about the Krebs cycle.
