Cellular Biology Lab – Homework #3 Due the week of Nov. 4th You may use the lab manual‚ pre-lab lectures‚ and credible internet resources‚ however you may not use your cell bio lab classmates as a resource. You will most likely see this material again on the Final and I highly encourage you to work individually and seek help from myself or your TA. Plagiarism will result in an automatic zero. 1. In the cell bio lab‚ we use company manufactured gels‚ however you can make you own polyacrylamide

atoms‚ which are the smallest units of matter. There are many different kinds of cells. The two kinds you are most likely to be familiar with are animal and plant cells. Some of the differences between them are that plant cells have a cell wall and chloroplasts. Cells all have different sizes‚ shapes‚ and jobs to do. The cells in a single organism may have different shapes‚ sizes‚ and jobs. Organisms like humans are made up of trillions of cells. There are also one-celled organisms such as euglenas

however it is not ideal for the duckweed to grow in shallow conditions. If the pond is too shallow than the freezing and evaporating point of the pond will fluctuate too much for the duckweed to grow. Duckweed is composed of a think cell wall‚ with chloroplasts‚ mitochondria‚ smooth ER‚ Rough ER‚ a vacuole‚ cytoplasm‚ goolgi body‚ nucleus‚ nucleolus. All these parts in duckweed help the plant carry out photosynthesis. Duckweed makes food just as any other plant and is an autotroph. The plant uses cellular

Biology Major substances: Organic compounds – are compounds that contain carbon and were originally made by living things e.g. carbohydrates‚ lipids‚ proteins‚ nucleic acids Inorganic compounds – are compounds do not contain carbon as a main element Organic compounds | Composition | Function | Proteins | Carbon‚ hydrogen‚ oxygen and nitrogen | Used in the structure‚ storage‚ movement and transport of cells for growth and repair. | Lipids | Carbon‚ hydrogen and oxygen | Stores energy

(genetic) information are located. Golgi Complex – This is an organelle found in eukaryotic cells. Therefore this would be found in both animal and plant cells. The main function of this cell is that it processes proteins for secretion. Chloroplasts – This is the organelle that carries out photosynthesis which makes energy for the cell. It is found in plant cells. Cytosol – This is the liquid portion of cells and is comprised mostly of water. This is where energy reactions and cell movement

In her article‚ “A Tale of Two Flagella‚” Olivia Judson (2010) states that the dinoflagellate is considered a plant‚ animal‚ predator‚ and a parasite. A dinoflagellate is defined as a large group of single celled organisms that can be helpful and harmful. Dinoflagellates are very diverse in characteristics and abilities. For example‚ some dinoflagellates perform photosynthesis‚ some have eyes‚ and others capture and eat prey. A dinoflagellate can look like a small brown ball that is structured as
