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.
Organelle Item used to represent Diagram Reason for selection and function
Cell membrane Solid 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.
Centrioles Raw 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.
Chromatin Plum 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.
The cytoplasm is the jelly-like material found around the nucleus. This is represented by the gelatine to fit the task.
Golgi Apparatus Dried 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.
Lysosomes are round organelles that contain digestive enzymes. This is represented by peanuts because they have a roundish feature as well.
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 Membrane Plum 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.
Nucleolus Plum seed
The plum seed symbolises the nucleolus because the seed is situated inside the...
