Step-by-step solution for: Plant Cell Worksheets -Worksheets Library
Let’s solve this step by step.
We are given a diagram of a plant cell with numbered parts (1 to 15), and on the left, there is a list of organelle names also numbered 1 to 15 — but they’re not in order. Our job is to match each number from the diagram to the correct organelle name from the list.
We’ll go one by one, using what we know about plant cell structure:
---
Step 1: Look at number 4 in the diagram.
It points to the outermost layer — that’s the cell wall. In the list, “CELL WALL” is #5. So → Diagram 4 = List 5
Wait — actually, let’s be careful. The list on the left has numbers too — those are just labels for the names. We need to match the *diagram number* to the *correct name*, regardless of the list’s numbering.
Actually, re-reading: The list on the left is labeled 1 to 15, and each line has a name. The diagram has numbers 1 to 15 pointing to structures. We must write which name goes with which diagram number.
So for example, if diagram label “1” points to a stack of discs, that might be Golgi body or something else.
Let’s use standard plant cell knowledge:
---
Diagram Number 1: Points to stacked flat sacs — that’s likely the Golgi body. In the list, “GOLGI BODY” is #15. So → Diagram 1 = Golgi Body (#15)
But wait — let’s check all carefully.
Actually, better approach: Let’s identify each diagram part based on shape and location.
---
Diagram 1: Stack of flattened membranes → Golgi apparatus → matches list #15 “GOLGI BODY”
Diagram 2: Large empty space inside cell → Vacuole → list #2 “VACUOLE”
Diagram 3: Jelly-like substance filling cell → Cytoplasm → list #3 “CYTOPLASM”
Diagram 4: Outer rigid layer → Cell Wall → list #5 “CELL WALL”
Diagram 5: Thin line inside cell wall → Cell Membrane → list #4 “CELL MEMBRANE”
Diagram 6: Star-shaped crystal? Wait — looks like a spiky ball → probably Druse Crystal → list #6 “DRUSE CRYSTAL”
Diagram 7: Network of tubes near nucleus → Endoplasmic Reticulum → list #7 “ENDOPLASMIC RETICULUM”
Diagram 8: Small dots floating or on ER → Ribosomes → list #8 “RIBOSOMES”
Diagram 9: Pair of cylinders near nucleus → Centrosome → list #9 “CENTROSOME”
Diagram 10: Oval with internal folds → Mitochondria → list #12 “MITOCHONDRIA”
Wait — hold on. Diagram 10 looks like a chloroplast? No — chloroplasts have thylakoids, mitochondria have cristae.
Actually, diagram 10: oval with inner folded membrane → classic mitochondrion → so #12
But let’s check diagram 14: green oval with stacks → that’s chloroplast → list #14 “CHLOROPLAST”
Diagram 13: large round structure with smaller circle inside → that’s nucleus with nucleolus → so diagram 13 = Nucleus (#11), and the small circle inside is nucleolus (#13)
Wait — diagram 11 is pointing to the small circle inside the big circle → that’s nucleolus → list #13 “NUCLEOLUS”
Diagram 13 is pointing to the whole big circle → nucleus → list #11 “NUCLEUS”
Diagram 12: another oval with folds → also mitochondria? But we already have one. Maybe it’s amyloplast? Amyloplasts store starch — often look similar but no cristae.
Looking again: Diagram 12 — oval with some internal structure, maybe less defined than 10 → could be amyloplast → list #10 “AMYLOPLAST”
Diagram 14: clearly has grana (stacks) → chloroplast → list #14 “CHLOROPLAST”
Diagram 15: wavy lines near top left → could be rough ER or smooth ER — but since 7 is already ER, maybe this is something else? Wait — diagram 15 points to a region with many small vesicles and tubules — actually, that might be part of ER or Golgi? But Golgi is already 1.
Wait — perhaps I made a mistake.
Let me restart with a clear table:
Standard plant cell parts:
- Cell wall: outermost → diagram 4
- Cell membrane: just inside cell wall → diagram 5
- Cytoplasm: fills cell → diagram 3
- Vacuole: large central sac → diagram 2
- Nucleus: large round organelle → diagram 13
- Nucleolus: inside nucleus → diagram 11
- Mitochondria: powerhouses, oval with cristae → diagrams 10 and 12? But usually multiple.
- Chloroplast: green, with thylakoids → diagram 14
- Golgi: stacked cisternae → diagram 1
- ER: network → diagram 7
- Ribosomes: tiny dots → diagram 8
- Centrosome: pair of centrioles → diagram 9
- Druse crystal: star-shaped calcium oxalate crystal → diagram 6
- Raphide crystal: needle-shaped — where is that? Diagram 15? It shows long thin rods — yes! Diagram 15 points to long thin crystals → that’s raphide → list #1 “RAPHIDE CRYSTAL”
- Amyloplast: stores starch — might be diagram 12? Or 10?
List item #10 is “AMYLOPLAST” — should be an organelle that stores starch, often colorless plastid.
Diagram 12: oval, no green, internal structure — could be amyloplast.
Diagram 10: more defined cristae — mitochondrion.
Diagram 13: nucleus → list #11
Diagram 11: nucleolus → list #13
Now let’s assign:
Diagram 1 → Golgi Body → list #15
Diagram 2 → Vacuole → list #2
Diagram 3 → Cytoplasm → list #3
Diagram 4 → Cell Wall → list #5
Diagram 5 → Cell Membrane → list #4
Diagram 6 → Druse Crystal → list #6
Diagram 7 → Endoplasmic Reticulum → list #7
Diagram 8 → Ribosomes → list #8
Diagram 9 → Centrosome → list #9
Diagram 10 → Mitochondria → list #12
Diagram 11 → Nucleolus → list #13
Diagram 12 → Amyloplast → list #10
Diagram 13 → Nucleus → list #11
Diagram 14 → Chloroplast → list #14
Diagram 15 → Raphide Crystal → list #1
Yes, that makes sense.
Double-check:
- Raphide crystal: long needles → diagram 15 → correct
- Druse: star-shaped → diagram 6 → correct
- Amyloplast: non-green plastid → diagram 12 → reasonable
- Mitochondria: diagram 10 → has cristae → correct
- Chloroplast: diagram 14 → has grana → correct
- Nucleus: 13, nucleolus: 11 → correct
- Golgi: 1 → stacked → correct
- ER: 7 → network → correct
- Ribosomes: 8 → dots → correct
- Centrosome: 9 → two cylinders → correct
- Vacuole: 2 → large central → correct
- Cytoplasm: 3 → background → correct
- Cell membrane: 5 → inner boundary → correct
- Cell wall: 4 → outer → correct
All matched.
