Based on the analysis of the image and the provided descriptions, here is the complete solution matching each numbered organelle to its correct description:
-
1. Mitochondria (A): The small, dark, oval-shaped structures are mitochondria, which are responsible for breaking down sugar to produce ATP, the cell's energy currency.
-
2. Plasma Membrane (C): The line points to the outer boundary of the cell. The plasma membrane is a semipermeable layer that controls what enters and exits the cell.
-
3. Nucleus (F): This is the large, purple, spherical organelle that contains the cell's genetic material (DNA) organized into chromosomes.
-
4. Vacuole (I): The small, green, sac-like structure is a vacuole, which functions as a storage compartment for various substances within the cell.
-
5. Ribosomes (G): The small dots shown are ribosomes, which are the sites of protein synthesis in the cell, found floating freely or attached to the rough ER.
-
6. Rough Endoplasmic Reticulum (J): The folded membrane pathways studded with ribosomes are the rough ER, involved in protein synthesis and membrane production.
-
7. Nuclear Membrane (H): This is the double membrane that surrounds the nucleus, controlling the movement of materials between the nucleus and the cytoplasm.
-
8. Golgi Apparatus (D): The stack of flattened vesicles is the Golgi apparatus, which modifies, sorts, and packages proteins for secretion or delivery to other organelles.
-
9. Lysosome (B): The small, red vesicle is a lysosome, containing digestive enzymes that break down waste materials and cellular debris.
-
10. Cytoplasm (E): The entire watery medium inside the cell where all the organelles are suspended is the cytoplasm.
This completes the matching of all organelles to their correct descriptions.
