Cell Structure exercise - Free Printable

The task involves labeling the parts of an animal cell and a plant cell based on the provided lists of organelles. Below is the solution with explanations for each part.

Animal Cell (Top Diagram)

The animal cell diagram is labeled as follows:

1. Nucleus: The large, central structure that contains the cell's genetic material (DNA). It is surrounded by a nuclear membrane.
- Label: Top center

2. Nucleolus: A dense region within the nucleus where ribosomal RNA is synthesized.
- Label: Inside the nucleus

3. Cytoplasm: The gel-like substance that fills the cell and surrounds the organelles.
- Label: Everywhere outside the nucleus but inside the cell membrane

4. Cell membrane: The outer boundary of the cell that regulates what enters and exits the cell.
- Label: Outer edge of the cell

5. Lysosome: Small, membrane-bound sacs containing digestive enzymes that break down waste materials and cellular debris.
- Label: Small, round structures scattered in the cytoplasm

6. Endoplasmic Reticulum (ER): A network of membranous tubules and sacs involved in protein and lipid synthesis.
- Label: Wavy, interconnected structures in the cytoplasm

7. Golgi Apparatus: A stack of flattened sacs that modifies, sorts, and packages proteins and lipids for transport.
- Label: Stacked, curved structures near the nucleus

8. Mitochondria: Organelles responsible for producing energy (ATP) through cellular respiration.
- Label: Bean-shaped structures with inner folds

9. Ribosome: Tiny structures where proteins are synthesized. They can be free-floating or attached to the ER.
- Label: Small dots scattered in the cytoplasm or attached to the ER

Plant Cell (Bottom Diagram)

The plant cell diagram is labeled as follows:

1. Ribosome: Tiny structures where proteins are synthesized. They can be free-floating or attached to the ER.
- Label: Small dots scattered in the cytoplasm or attached to the ER

2. Cytoplasm: The gel-like substance that fills the cell and surrounds the organelles.
- Label: Everywhere outside the nucleus but inside the cell wall

3. Golgi Apparatus: A stack of flattened sacs that modifies, sorts, and packages proteins and lipids for transport.
- Label: Stacked, curved structures near the nucleus

4. Mitochondria: Organelles responsible for producing energy (ATP) through cellular respiration.
- Label: Bean-shaped structures with inner folds

5. Chloroplasts: Organelles containing chlorophyll, which are responsible for photosynthesis.
- Label: Green, disc-shaped structures with internal membranes

6. Endoplasmic Reticulum (ER): A network of membranous tubules and sacs involved in protein and lipid synthesis.
- Label: Wavy, interconnected structures in the cytoplasm

7. Vacuole: A large, membrane-bound sac that stores water, nutrients, and waste products.
- Label: Large, central sac in the cytoplasm

8. Nucleus: The large, central structure that contains the cell's genetic material (DNA). It is surrounded by a nuclear membrane.
- Label: Central, large structure

Explanation

- Animal Cells lack a cell wall, chloroplasts, and a large central vacuole, which are characteristic features of plant cells.
- Plant Cells have additional structures like a rigid cell wall, chloroplasts for photosynthesis, and a large central vacuole for storage.

By identifying these key differences and matching the organelles to their descriptions, the labels can be accurately placed.
