Let's complete the table by identifying each organelle based on its
shape and
function.

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 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 (green oval with green lines) | 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, round granules (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.
-
Smooth ER lacks ribosomes and is involved in lipid synthesis and detoxification.
3.
Golgi Apparatus
-
Shape: Stack of flattened membranous sacs.
-
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, cellular debris, and foreign particles.
5.
Mitochondrion
-
Shape: Double-membraned, bean-shaped with inner folds (cristae).
-
Function: Site of cellular respiration; produces ATP (energy currency of the cell).
6.
Vacuole
-
Shape: Large, spherical membrane-bound sac.
-
Function: Stores water, ions, nutrients, and waste products. In plant cells, it maintains turgor pressure.
7.
Chloroplast
-
Shape: Oval with stacked thylakoids (grana).
-
Function: Site of photosynthesis in plant cells; converts light energy into chemical energy (glucose).
8.
Centriole
-
Shape: Two cylindrical structures arranged at right angles (often shown as a "Y" shape).
-
Function: Organizes microtubules during cell division; forms the spindle fibers that separate chromosomes.
