The Jelly Cell is the second task of the Cells unit and is undoubtedly a more enjoyable assessment compared to cells online which was the previous task. Despite this, it is still an important assessment as it contributes five marks to the working scientifically criteria for term two. Because of its significance, a number of standards must be set to ensure the task is done to the best of my ability.
Apart from accuracy, neatness, completeness, amount of technical detail, labelling of structures, originality and relationship of knowledge to cell construction, I would specifically like to focus on two main standards. Those are the accuracy of the justification of the model and the similarity between the shapes of the food products chosen to the real organelles.
The table below shows the food products that I have chosen for each organelle.
OrganelleItem used to representDiagramReason for selection and function
Cell membraneSolid plastic container
The cell membrane is a thin layer of protein and fat that surround the cell. It is represented by a transparent plastic container so it is easier to see the organelles inside and more portable.
CentriolesRaw spaghetti noodles
The Centrioles is a small body located near the nucleus which creates microtubules. This is represented by a group of spaghetti noodles because the stick like shape of the centriole is also found in spaghetti noodles.
The Term Paper on Structure And Function Of Eukaryotic Cell Organelles
Nearly all animal cells have a nucleus, with the only exception being the red blood cell. The nucleus has two major functions, which are housing the DNA and controlling the cell’s activities. In the centre of the nucleus is the nucleolus. This doesn’t have a membrane, but holds itself together. In the nucleolus, ribosomes are created through the mixture of RNA and proteins. These proteins are ...
ChromatinPlum meat
The chromatin is found in the nucleus and contains DNA and RNA and various proteins that form chromosomes during meiosis. This is represented by the plum meat found inside the plum just like how the chromatin is found inside the nucleus.
CytoplasmJELLY
The cytoplasm is the jelly-like material found around the nucleus. This is represented by the gelatine to fit the task.
Golgi ApparatusDried aniseed
The Golgi Apparatus is a sac like organelle that produces the membranes that surround the Lysosome. This is represented by the dried aniseed because this product contains sac-like features like the Golgi Apparatus.
LysosomePeanuts
Lysosomes are round organelles that contain digestive enzymes. This is represented by peanuts because they have a roundish feature as well.
MitochondriaCashew
The mitochondria are a rod-shaped organelle that converts energy stored in glucose into ATP. This is represented by cashews because they rod-shaped.
Nuclear MembranePlum Skin
The nuclear membrane surrounds the nucleus and is represented by the plum skin. This is quite convenient because the skin naturally surrounds the plum so no additional work is needed.
NucleolusPlum seed
The plum seed symbolises the nucleolus because the seed is situated inside the plum similar to the nucleolus in relation to the nucleus.
NucleusPlum
The nucleus controls many of the functions of the cell and is represented by the plum because the plum contains a membrane and a core just like the nucleus.
RibosomesSesame Seeds
The sesame seeds are used to represent ribosomes because they are small. Ribosomes are small organelles composed of RNA.
Rough Endoplasmic RecticulumDry black fungus + sesame seeds
The rough ER are infolded sacks that produces protein and are covered in ribosomes to give it the rough surface. However, in the jelly cell, the fungus is covered in sesame seeds. The fungus is a folded product so it looks similar to the rough ER. This is represented by the dry black fungus.
The Term Paper on Fungus Organic Matter
Fungus The Latin word for mushroom is fungus (plural, fungi). The word fungus has come to stand for a whole group of simple plants that contain no chlorophyll and lack such complex plant structures as roots, stems, leaves, and flowers. Included among the fungi, along with mushrooms, are molds, mildews, rusts, smuts, truffles, and yeasts. Toadstool is another name for mushroom. Some people use the ...
Smooth Endoplasmic RecticulumDry black fungus
The smooth ER is similar to the rough ER except it produces lipids and membrane protein. They are however, not covered in ribosomes so they are smooth. This is represented by the dry black fungus as well except this time, it is not covered in sesame seeds.
