Step-by-step solution for: Cell Organelles - Worksheet | Distance Learning
Let's complete the table by identifying each organelle based on its shape and function.
---
| Name of Organelle | Shape of Organelle | Function of Organelle |
|------------------------|------------------------|----------------------------|
| Ribosome | Small, round (blue dot) | Protein synthesis |
| Endoplasmic Reticulum (ER) | Network of membranes (green wavy structure) | Be smooth (no ribosomes) or rough (with ribosomes) and is associated with packaging, synthesis, and transport of materials in the cell. |
| Golgi Apparatus | Stack of flattened sacs (orange stacked structure) | Processing, packaging, and distribution of molecules |
| Lysosome | Small, spherical vesicle (yellow circle) | Vesicle that contains substances that break down materials. |
| Mitochondrion | Bean-shaped (red oval with folds) | Power plants of cells where energy (ATP) is produced. |
| Vacuole | Large, round sac (blue circle) | Temporarily stores food, water, waste; rather large in plant cells. |
| Chloroplast | Green, oval with internal stacks (like a stack of coins) | Found in plants and is where photosynthesis occurs. |
| Centriole | Two perpendicular cylinders (Y-shaped red structure) | Found in animal cells and is used in cell division; the spindle fibers attach to it. |

1. Ribosome
- Shape: Small, granular structures (often shown as blue dots).
- Function: Site of protein synthesis. They read mRNA and assemble amino acids into proteins.
2. Endoplasmic Reticulum (ER)
- Shape: Network of folded membranes (smooth or rough).
- Function:
- Rough ER has ribosomes attached and helps in protein synthesis and transport.
- Smooth ER lacks ribosomes and is involved in lipid synthesis and detoxification.
3. Golgi Apparatus
- Shape: Stack of flattened sacs (like pancakes).
- Function: Modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.
4. Lysosome
- Shape: Small, spherical vesicles.
- Function: Contains digestive enzymes to break down waste materials, cellular debris, and foreign particles.
5. Mitochondrion
- Shape: Double-membraned, bean-shaped with inner folds (cristae).
- Function: Produces ATP through cellular respiration—called the "powerhouse" of the cell.
6. Vacuole
- Shape: Large, fluid-filled sac (especially prominent in plant cells).
- Function: Stores water, nutrients, ions, and waste products. In plant cells, it also helps maintain turgor pressure.
7. Chloroplast
- Shape: Oval, green organelle with stacked thylakoids (grana).
- Function: Site of photosynthesis in plant cells—converts light energy into chemical energy (glucose).
8. Centriole
- Shape: Paired cylindrical structures (often shown as two perpendicular rods).
- Function: Organizes microtubules during cell division (mitosis); forms the spindle fibers that pull chromosomes apart.
