Step-by-step solution for: Grade 6-8 - Structure and Function - Organelles, Cells, and ...
Let's solve this step-by-step by identifying each labeled part in the diagram of animal and plant cells.
We are comparing a typical animal cell (on the left) and a plant cell (on the right). Both share many organelles, but plant cells have some unique structures like the cell wall, chloroplasts, and a large central vacuole.
Here’s the labeling based on standard cell biology:
---
- This is the outer boundary of the cell that regulates what enters and exits.
- Present in both animal and plant cells.
- In the plant cell, it lies just inside the cell wall.
> ✔ Label: Cell Membrane
---
- A rigid structure found only in plant cells (and some other organisms).
- Provides structural support and protection.
- Made primarily of cellulose.
> ✔ Label: Cell Wall
---
- The control center of the cell; contains DNA.
- Surrounded by the nuclear envelope.
- Found in both plant and animal cells.
> ✔ Label: Nucleus
---
- The double membrane surrounding the nucleus.
- Contains pores for material exchange between nucleus and cytoplasm.
> ✔ Label: Nuclear Envelope
---
- A structure within the nucleus where ribosomes are made.
- Often appears as a dark spot inside the nucleus.
> ✔ Label: Nucleolus
---
- Organelle responsible for cellular respiration (producing ATP).
- Present in both plant and animal cells.
> ✔ Label: Mitochondrion
---
- The genetic material inside the nucleus (appears as thread-like structures).
- Sometimes shown as chromatin or chromosomes depending on cell cycle phase.
> ✔ Label: Chromatin (or DNA)
---
- Network of membranes involved in protein and lipid synthesis.
- Rough ER has ribosomes on its surface (shown here with dots).
- Smooth ER lacks ribosomes.
> ✔ Label: Rough Endoplasmic Reticulum (Rough ER)
---
- Modifies, sorts, and packages proteins and lipids for transport.
- Looks like a stack of flattened sacs.
> ✔ Label: Golgi Apparatus
---
- Small structures that make proteins.
- Found free in the cytoplasm or attached to the rough ER.
> ✔ Label: Ribosomes
---
- Found only in plant cells.
- Site of photosynthesis; contains chlorophyll.
- Green in color (as shown).
> ✔ Label: Chloroplast
---
- Large central vacuole in plant cells (much larger than in animal cells).
- Stores water, ions, and waste products; helps maintain turgor pressure.
- Animal cells may have smaller vacuoles.
> ✔ Label: Vacuole (Central Vacuole in Plant Cell)

1. Cell Membrane
2. Cell Wall
3. Nucleus
4. Nuclear Envelope
5. Nucleolus
6. Mitochondrion
7. Chromatin (or DNA)
8. Rough Endoplasmic Reticulum (Rough ER)
9. Golgi Apparatus
10. Ribosomes
11. Chloroplast
12. Vacuole

✔ Summary: This diagram highlights key differences:
- Plant cell has: Cell wall, Chloroplasts, and large central vacuole.
- Animal cell has: No cell wall, no chloroplasts, and smaller vacuoles.
Both share: Nucleus, mitochondria, ER, Golgi, ribosomes, lysosomes (not labeled here), etc.
