Discussion Activity #1 Instructions

For this discussion activity, you are required to use creativity and your understanding of cells and their structures to produce an original work demonstrating your knowledge of cells, organelles, and other cellular structures. After creating your original work, review your classmates' submissions and provide constructive feedback. Finally, revise your own work based on the feedback received and post the final version in your concluding post at the end of the week.

Choose either a prokaryote (such as bacteria) or a eukaryote (such as an animal or plant cell) and clearly specify your choice in your post's subject line. Select a creative medium (drawing, song lyrics, poem, activity, mathematical comparison, or metaphor) to represent your chosen cell. Your work must include at least five different organelles or sub-cellular structures.

Publish your original work as a new thread in the discussion forum with an appropriate subject line. Do not attach files unless you have created an audio or video file.

For response posts, reply to at least two classmates, including a greeting, a positive comment, and a constructive suggestion for improvement, followed by a closing with your name. Ensure your comments are at least 3-4 sentences long and reflect college-level writing standards.

For your summary/concluding post, review all original and response posts, revise your original work based on feedback or personal reflection, and post the improved final version. Include a brief description of the changes made. Do not create a new thread; reply to your original post, and make your final submission after Saturday night.

A grading rubric is available in the grade book for your reference. Review it before submitting your work to understand how your grade will be determined.

Sample Paper For Above instruction

Creative Representation of a Eukaryotic Animal Cell

Chosen Cell Type: Eukaryotic Animal Cell

Title: The Busy City of Cellópolis

Imagine my cell as a bustling city, teeming with vital structures working together seamlessly. At the heart of this city lies the nucleus, the city hall, housing all the essential information needed to keep the city running. Surrounding it are various districts, each representing different organelles that perform unique functions crucial to the cell’s life.

First, the nucleus is depicted as a large, fortified city hall, controlling the activities of the cell. Its nuclear envelope acts like the city’s security gates, regulating what enters and leaves. Inside, the chromatin resembles the city's archives, storing genetic information that coordinates all activities.

Next, the endoplasmic reticulum (ER) is imagined as a vast transportation network. The rough ER is like a factory district with production lines studded with ribosomes, which function as skilled workers assembling proteins. The smooth ER is a series of pipelines for detoxification, lipid synthesis, and calcium storage, acting as waste management and resource distribution centers.

The mitochondria within this city are power plants, providing energy for all activities. Their double membrane resembles a complex filtration system—akin to a power station powered by fuel and machinery. The mitochondria generate ATP, the energy currency fueling every city operation.

The Golgi apparatus is thought of as the postal service center, sorting, packaging, and dispatching proteins and lipids to their destinations. Its series of flattening sacs resemble a well-organized distribution hub ensuring efficient delivery across the city.

Finally, the cytoskeleton forms the city's infrastructure—roads and bridges that maintain structural integrity and facilitate movement within the city. Microtubules and actin filaments are like the city's transportation routes used by vehicles and pedestrians to traverse distances efficiently.

This creative analogy helps visualize the complex yet organized functions of a eukaryotic animal cell, highlighting the importance of each organelle in maintaining cellular life. By imagining these components as parts of a city, it becomes easier to understand their interconnected roles in supporting biological functions.
