Let me carefully match each numbered structure in the diagram to its correct description from the list A–J.
First, I’ll identify each labeled part by zooming in and comparing with the descriptions.
-
1: This points to the outer boundary of the whole cell. The description that fits is
C. Plasma Membrane — “The protective outside layer of the cell that lets some things in and keeps others out (semipermeable).”
-
2: This points to the jelly-like material filling the cell, where organelles float. That’s
E. Cytoplasm — “The watery medium in which the organelles float inside the cell.”
-
3: This is a large, round structure near the center — clearly the control center. That matches
F. Nucleus — “The organelle that contains all our genetic information in 23 pairs of chromosomes making up our DNA.”
-
4: A small, round dot — likely a lysosome (digestive vesicle). Matches
B. Lysosome — “Vesicles with digestive enzymes to break down waste and bacteria.”
-
5: Two oval-shaped structures with inner folds — classic mitochondria. Matches
A. Mitochondria — “Double-membraned organelles that break down sugar to make ATP to be used as energy by the cell.”
-
6: A stack of flattened sacs — this is the Golgi apparatus. Matches
D. Golgi Apparatus — “Made up of flat vesicles that package things to leave the cell — like hormones.”
-
7: The membrane surrounding the nucleus. That’s
H. Nuclear Membrane — “Surround the nucleus and controls what goes in and out.”
-
8: A network of membranes with dots (ribosomes) on it — rough ER. Matches
J. Rough Endoplasmic Reticulum (rough ER) — “Folded membrane pathways spotted with ribosomes and making new membranes as needed.”
-
9: A small, empty-looking sac — likely a vacuole. Matches
I. Vacuole — “Membrane sacs for storage.”
-
10: Small grain-like structures, some free-floating and some on ER — these are ribosomes. Matches
G. Ribosomes — “Little grains floating around inside the cell and on the rough ER where proteins are made.”
Now I’ll list each number with its correct letter:
1 → C
2 → E
3 → F
4 → B
5 → A
6 → D
7 → H
8 → J
9 → I
10 → G
Final Answer:
1-C, 2-E, 3-F, 4-B, 5-A, 6-D, 7-H, 8-J, 9-I, 10-G
