Animal cell project

The Nucleus is found in both the animal cell and the plant cell. The Nucleus function is to direct all functions within the cell. 5. Nucleolus The Nucleolus is found in the nucleus in both plants and animal cells. The nucleolus function is to assemble ribosomes which move out of the nucleus and take positions on the rough ER (Endoplasmic Reticulum) where they are critical in protein synthesis. 6. Chromatin The Chromatin is located in both plant cells and animal cells. The function of the hromatin is to package DNA into a smaller volume to fit in the cell, to strengthen the DNA to allow mitosis and prevent DNA damage. 7. Centrioles Centrioles are found only in the animal cell. The function of Centrioles is to produce the cells cytoskeleton which is made up of microtubules and microfilaments. Chloroplast The chloroplast is located only in the plant cell. Chloroplast Job is responsible for making glucose in the process known as photosynthesis. The Chloroplast is green due to chlorophyll a pigment that captures sunlight. The chloroplasts live in the mesophyll cells. 8. Ribosomes Ribosomes are found in both plant and animal cells. The function is to synthesize and make proteins. Ribosomes can be found free floating in the cytoplasm or attached to the ER (Endoplasmic Reticulum). 9. Vacuoles Vacuoles are found in both plant cells and animal cells. The vacuoles function is to store food, water, or wastes. The vacuole that is only found in plant cells is the central vacuole. The vacuoles store water, food, and waste. Vacuoles purpose is to serve rimarily as storage units but versatile to perform more than one function. Cell Wall Cell walls are located only in the plant cell. The function of the cell wall is to support and give structure. The cell wall is made up of cellulose. 10. Cell Membrane Cell membranes are located in both plant and animal cells. The Job of the cell membrane is to control what foes into and out of the cell. 11 . Cytoplasm Cytoplasm is found in both plants and animal cells. The Job of the cytoplasm is to keep the organelles safe and in place. 12. Nuclear Envelope The Nuclear Envelope is located in both the plant cell and the animal cell. The nuclear envelopes function is to send a stream of RNA and other info-carrying molecules to the rest of the cell through nuclear pores. These organelles I have listed are in animals and in plant cells or both. The lists of organelles are very unique and if you have never heard of these organelles and cells. I hope you will learn something from my project. In conclusion, my project is to show the similarities and differences between each organelle in a plant cell or animal cell.

Fresh Tec Case Study Example | Topics and Well Written Essays - 1500 words

Fresh Tec - Case Study Example First, there was the naturally occurring aging and decaying process of fruits and vegetables, known as senescence. Senescence involved transpiration and respiration, processes that went on in the fresh produce even after being detached from the mother-plant. Secondly, the kind of packaging used for delivery and storage did nothing to extend the life of harvested produce or effectively alleviate senescence. Instead, the packaging necessitated quicker, and costlier, options of delivery from the farms to the consumers, and all the agents that fall in-between. Thirdly, the produce was prone to physical injury, temperature injury and disease. The physical injury was mostly caused by shipping produce in splintered or damaged crates and boxes, or the way the shipping was handled. Such injuries presented bacteria with entry points, resulting in diseases. Most modern packinghouses invested in the use of washing and spraying fungicides before shipping to reduce chances of disease, but had no g reat impact on how long the produce could stay after harvesting. Temperature injury was caused by extreme temperatures both during storage and shipping, soon rendering produce unsuitable for the market. Given all these external factors, FreshTec was not well positioned to be much more successful in the industry than other players, because they would all use the same processes and players involved. FreshTec saw a single solution to all the factors degrading the quality of produce in all its processes and stages before finally reaching the consumer; packaging. The right type of packaging could increase the life of produce. The retailers and warehouse operators would be able to keep more stocks for longer without having to throw them away as waste when they went bad (USDA, 2010). The farmers, marketers, brokers and distributors would choose cheaper delivery and shipping methods that, although take longer, keep produce fresh, retain moisture contents and keep produce tasting sweet. This aspect would also enable consumers to have off-season produce that has been stored from the last harvest, because the packaging and storage enables them to last longer. SmartPac, developed by FreshTec, offered customized modified atmosphere packaging (MAP) for any variety of produce. This enabled them to climb an edge above all previous technique. The packaging exchanged heat from the box, allowing sealed contents to be cooled while using a naturally oxidizing sanitation system to sterilize and clean produce during transit. In this way, FreshTec could ensure produce reached the consumer while still fresh, undamaged and naturally sweet. This also eliminates the need of having to harvest farm products before they are optimally ripe. Fresh produce had to be harvested just before ripening in order to allow for senescence during transportation to distant destinations, tempering with natural taste. Question Two FreshTec may use several options to approach the issue of industry adoption o f their new packaging. The first would be to justify the cost of the new packaging, which averaged at an extra $1 to $1.5 in comparison to standard packaging. All this was in view that the new packaging was being launched into a tradition-bound and conservative industry. However, if the produce could still be delivered cheaply for longer periods and reach new markets that were previously inaccessible while still fresh, the pricing burden can easily be shared between the retailers and consumers.

PowerPoint slides, and videos of Topic 3, selected ONE issue of Essay

PowerPoint slides, and videos of Topic 3, selected ONE issue of significance and relevance to our time - Essay Example Fighting on behalf of God in the event that one is wronged makes the religion to be viewed as intolerable to the human race that are bound to do wrong. In the video interviews with Hamza Yusuf, it is evident that the Islamic religion has gone through a number of changes as it tries to fully entrench itself in the Western countries such as the United States. After the happenings of 11th September 2001, the view of Islamic religion has been changed to that of a religion marked and characterized by war and terror which has also been witnessed recently in other parts of the world. However,-Hamza Yusuf (1/6, 10mn)-Hamza argues that acts of terrorism should not be limited to those who profess the Islamic religion only hence the Muslims need not to be subjected to such accusations. It is a known case that people who profess other religions such as Christianity, have also lead to the death of many people such as the 1994 Rwanda genocide in which both communities involved were
