Let's complete the table by identifying each organelle based on its
shape (as shown in the image) and
function. Here’s the completed table with explanations:

✔ Completed Table:
|
Name of Organelle |
Shape of Organelle |
Function of Organelle |
|------------------------|-------------------------|----------------------------|
|
Ribosome | Small, round (blue dot) | Protein synthesis |
|
Endoplasmic Reticulum (ER) | Network of membranes (green wavy lines) | 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 stacks) | Processing, packaging, and distribution of molecules |
|
Lysosome | Small, round vesicle (yellow circle) | Vesicle that contains substances that break down materials |
|
Mitochondrion | Double-membraned, bean-shaped (red structure) | 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 structures (green oval) | 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 |

🔍 Explanation of Each Organelle:
1.
Ribosome
-
Shape: Small, spherical structures (often seen as dots).
-
Function: Site of protein synthesis. They read mRNA and assemble amino acids into proteins.
2.
Endoplasmic Reticulum (ER)
-
Shape: Network of folded membranes (rough ER has ribosomes attached; smooth ER does not).
-
Function: Involved in protein and lipid synthesis, detoxification, and transport of materials within the cell.
3.
Golgi Apparatus
-
Shape: Stack of flattened membrane sacs (like a stack of pancakes).
-
Function: Modifies, sorts, and packages proteins and lipids for storage or transport out of the cell.
4.
Lysosome
-
Shape: Small, spherical vesicle.
-
Function: Contains digestive enzymes that break down waste materials, old organelles, and foreign particles.
5.
Mitochondrion
-
Shape: Bean-shaped with an inner folded membrane (cristae).
-
Function: Produces ATP through cellular respiration — the "powerhouse" of the cell.
6.
Vacuole
-
Shape: Large, spherical sac.
-
Function: Stores water, nutrients, and waste. In plant cells, it maintains turgor pressure and helps maintain cell shape.
7.
Chloroplast
-
Shape: Oval with stacked green membranes (thylakoids).
-
Function: Site of photosynthesis in plant cells — converts light energy into chemical energy (glucose).
8.
Centriole
-
Shape: Paired cylindrical structures arranged perpendicularly (Y-shape in diagram).
-
Function: Organizes microtubules during cell division (mitosis); forms the spindle fibers that pull chromosomes apart.
