Explain the structure and function of the mitochondria. 16. What function does the cell wall perform in a plant? 17. What similarities do mitochondria and chloroplasts share? 18. Describe how the endoplasmic reticulum‚ mitochondrion and Golgi apparatus are structurally similar. 19. Medicine‚ alcohol and many drugs are detoxified in liver cells. Why do you think the liver cells of some people who abuse alcohol and drugs have an increased amount of smooth ER? 3.3. Cell Membrane:

In Crash Course video number four you learn animal cells and how they operate more like a city. Hank calls this city Eukaryopolis- The city of animal cells. He also goes over what each part of the cell and how the animal cells are responsible for different things that happen in our body. The very start of video starts off comical by showing you the difference between what an animal is and is not. Then it goes on to explain that why a eukaryotic because they have a “true kernel‚ meaning good nucleus

Synaptic transmission Objectives: To describe the process of electrical transmission between neurones. To highlight the differences between chemical and electrical transmission. To describe the process of chemical transmission. To explain the electrical events associated with chemical transmission ELECTRICAL TRANSMISSION Direct flow of ions from one neurone to another (direct influence of electric current from one to another) E.g. gap junction Gap junction: directly connects the cytoplasm

What does it mean for this process to be anaerobic? (a) No oxygen is required. (b) No oxidation occurs. (c) It takes place in the lysosome. (d) Glucose is broken down by the addition of electrons. 13-2 Which of the following stages in the breakdown of the piece of toast you had for breakfast generates

1. A. Homeostasis is defined as a condition of equilibrium in the body internal environment. For example the internal organs‚ behaviors‚ body temperatures. In homeostasis it can be considered as dynamic as it is always changing. The liver‚ kidneys‚ autonomic nervous system and endocrine system‚ and hypothalamus help maintain homeostasis. For example‚ my brother has imbalance homeostasis due to having seizures. Because his brain is not functioning correctly‚ his homeostasis is not balance. B. Medial

The cell is one of the most basic units of life. There are millions of different types of cells. There are cells that are organisms onto themselves‚ such as microscopic amoeba and bacteria cells. And there are cells that only function when part of a larger organism‚ such as the cells that make up your body. The cell is the smallest unit of life in our bodies. In the body‚ there are brain cells‚ skin cells‚ liver cells‚ stomach cells‚ and the list goes on. All of these cells have unique functions

cytoskeletal microtubes and thus spindles cannot be formed so cell division is prevented. During telophase taxol causes the reversal of prophase events such as the chromosomes decondense‚ spindle disassembly‚ nuclear envelope reformation‚ the Golgi apparatus and E.R. reform and the nucleus also reforms. Cytokinesis effects are that the cell still divides for animal cells a cleavage furrow made of actin and myosin II constricts the middle of the cell and in plants the phragmoplast forms at the equator
