Explanation:

1. The yellow structure is a skeletal muscle fiber (a specialized muscle cell). Its role is to contract to produce body movement, maintain posture, and generate heat.
2. Cells have diverse organelles to divide labor; each structure performs a specific specialized function (e.g., energy production, protein synthesis) to keep the cell and organism functioning efficiently.
3. Cell walls are rigid, made of cellulose (in plants), found only in plant/fungal/bacterial cells, and provide structural support. Cell membranes are flexible, made of lipids/proteins, present in all cells, and regulate what enters/exits the cell.
4. There are more tissues than organs. Organs are made up of multiple different types of tissues, so each organ relies on several tissue types, leading to a greater total number of tissues in the body.
5. Three key differences: 1) Plant cells have a rigid cell wall outside the cell membrane; animal cells do not. 2) Plant cells contain chloroplasts for photosynthesis; animal cells do not. 3) Plant cells have a large central vacuole for storage/water balance; animal cells have small or no vacuoles.
6. A cell model makes tiny, invisible cell structures tangible and scaled up. It can highlight the shape, location, and relationship between organelles, helping visitors visualize and connect each structure to its specific function more easily than text alone.

Answer:

1. The yellow structure is a skeletal muscle cell (fiber). It contracts to enable movement, maintain posture, and produce heat.
2. To divide specialized functions (cell specialization/labor).
3. - Cell walls: Rigid, cellulose-based (plants), only in some cells, for support.

• Cell membranes: Flexible, lipid/protein, all cells, regulates transport.

1. More tissues. Organs are composed of multiple tissue types, so the total number of tissues exceeds the number of organs.
2. 1. Plant cells have a cell wall; animal cells do not.
3. Plant cells have chloroplasts; animal cells do not.
4. Plant cells have a large central vacuole; animal cells have small/no vacuoles.
5. Models make tiny cell structures visible, show organelle positions, and link structure to function for easier understanding.
