Mitochondria:
- The site of aerobic respiration where ATP (cellular energy) is produced.
- They are 0.5-1.5 µm wide and 3-10 µm long.

2) Lysosome:
- Contains digestive enzymes which are kept separate from the cytoplasm by the surrounding membrane, but can be used to digest invading cells or break down worn out components of cell.
- Its size is 0.5-5 µm in diameter.

3) Golgi Apparatus:
- Synthesises and modifies proteins, lipids and carbohydrates. It also makes ‘Lysosomes’.
- Its size is 2.5 µm in length.

4) Ribosomes:
- The site of protein synthesis (or production of protein)
- Its size is 0.025 µm in diameter.

5) Nucleus:
- Contains the cell’s genetic material (DNA) and controls all the cell’s processes.
- Its size is 5-10 µm in

    BIOL 1010 ASSIGNMENT 1 OCT 6 BY JORDAN KAPITANY ST 100883963 Among the many scientific achievements of the twentieth century in the field of bio-technology scientists Paul Berg, Herbert W Boyer, Stanley N Cohen and team for their research that lead the party to discover a technique of taking genes from one organism and inserting them into another organism, also more formally known as Deoxyribonucleic Acid or DNA recombinant technology. In 1971 Berg and team successfully isolated DNA of virus found in monkey's known as lambda then placed the genetic material into DNA sequence of a different simian virus called SV4O. This was done by first using a DNA enzyme, a naturally occurring molecule that has the unique chemicals properties to sever the bonds in the DNA sequence, from a very specific kind of…

    A membrane surrounds the lysosomes and it keeps the enzymes enclosed within it. Lysosomes contain powerful digestive enzymes, which helps to break down the material e.g. white blood cells. Ribosomes 3) Ribosomes are non-membrane- bounded particles that float free in the cytoplasm or it is usually attached to the rough endoplasmic reticulum (ER). It is made of RNA, protein and is site for protein synthesis.…

    Cells rely on ribosomes when they need to produce more protein. They are found in all living cells and they host protein synthesis. They can occur as free particles in prokaryotic and eukaryotic cells and also attaches to the membranes of endoplasmic reticulum in eukaryotic cells. When it comes to size, ribosomes are roughly spherical and usually measure 200 angstroms in diameter. To get an idea of how small this is, imagine trying to pick one little speck of dirt in your yard.…

Description of non-pathogen: B. subtilis is a mesophilic, gram-positive bacillus that is commonly found in soil, although it can also survive in plants (1). B. subtilis are facultative aerobes, using butanediol fermentation or nitrated ammonification when oxygen is unavailable (1). The bacillus is motile by using a single flagellum and commonly forms biofilms which contain several B. subtilis all traveling in the same direction (1).…

    Centrosomes are also present and they contain important spindle fibers which develop during the process of cell division. Main Functions: Endoplasmic Reticulum- a network of tubular membranes within the cytoplasm of the cell, occurring either with a smooth surface (smooth endoplasmic reticulum) or studded with ribosomes (rough endoplasmic reticulum) involved in the transport of materials. Nucleus- a dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane, containing the genetic material (Contains: nuclear pore, nucleolus, nucleoplasm, and nuclear envelope) Golgi Apparatus-…

    Food is first broken down mechanically, by chewing, and is then progressively broken down chemically by various enzyme and other chemical reactions before entering the small intestine. As the food bolus, now converted to a semi liquid chyme becomes broken down into simpler component parts, it can be absorbed by the vili. The vili allow amino acids and glucose to pass into the blood, and lipids and glycerols or sugar alcohols to pass into the lymph, where they can be moved to wherever they are…

    Introduction: - Mitochondria is a double membrane organelle that is found in all eukaryotic organism. There are some evidences that proves that some of the eukaryotic organism lack this organelle but there is no true evidence which says that this specific organism completely lacks mitochondria. Mitochondria is also known as a power house of the living body cell. It stores energies in the cell and releases when its needed. Every organelle in Mitochondria have their own specific roles which helps in storing energy (See Figure 1 for details).…
