Transcribed Image Text:### Structure of a Prokaryotic Cell
**Diagram Description:**
The diagram presents a labeled illustration of a prokaryotic cell. The cell is depicted in an elongated, oval shape with various internal structures. The diagram includes labels with letters from A to G pointing to different parts of the cell.
- **A:** Capsule
- **B:** Cell wall
- **C:** Plasma membrane
- **D:** Cytoplasm
- **E:** Ribosome
- **F:** Nucleoid
- **G:** Flagellum
**Explanations for Structures:**
1. **Capsule (A):**
- This is the outermost layer, which offers protection to the cell and helps in attachment to surfaces.
2. **Cell Wall (B):**
- A rigid layer that provides the cell with structural support and shape.
3. **Plasma Membrane (C):**
- The membrane inside the cell wall that controls the movement of substances in and out of the cell.
4. **Cytoplasm (D):**
- A jelly-like substance within the cell where various cellular processes occur.
5. **Ribosome (E):**
- Small structures within the cytoplasm responsible for protein synthesis.
6. **Nucleoid (F):**
- An irregularly-shaped region containing the cell's DNA.
7. **Flagellum (G):**
- A tail-like structure that enables the cell to move.
**Interactive Elements:**
Below the diagram, there is an interactive section where users can match the labels (A-G) with the corresponding cell parts from a drop-down menu. The options available in each drop-down are: Capsule, Plasma membrane, Cytoplasm, Cell wall, Ribosome, Flagellum, Nucleoid.
This diagram serves as an introductory overview of the fundamental structures found in prokaryotic cells, highlighting the simplicity and efficiency of these unicellular organisms.
