Plant Cell and Animal Cell Diagram Quiz - Free Printable

Based on the analysis of the provided diagram, here is the identification of each labeled part in both the plant and animal cells:

- A: Cell Wall - A rigid outer layer found only in plant cells, providing structural support and protection.
- B: Cell Membrane (Plasma Membrane) - A semi-permeable membrane that surrounds the cytoplasm, regulating the movement of substances in and out of the cell. It is present in both plant and animal cells but lies just inside the cell wall in plant cells.
- C: Cytoplasm - The gel-like substance within the cell membrane that contains all the organelles. It is present in both plant and animal cells.
- D: Vacuole - A membrane-bound sac for storage. In plant cells, it is typically a single, large central vacuole. In animal cells, there are multiple smaller vacuoles.
- E: Nucleus - The control center of the cell, containing the cell's genetic material (DNA). It is present in both plant and animal cells.
- F: Mitochondrion - The organelle responsible for producing energy (ATP) through cellular respiration. It is present in both plant and animal cells.
- G: *(Not explicitly asked, but based on context, this likely points to the Golgi apparatus or another organelle near the nucleus. However, without a clear zoom, we'll focus on the labeled letters.)*
- H: Chloroplast - An organelle found only in plant cells (and some protists) that conducts photosynthesis. It contains chlorophyll, which captures light energy.
- I: Nucleolus - A dense region within the nucleus where ribosome assembly begins. It is present in both plant and animal cells.
- J: Endoplasmic Reticulum (ER) - A network of membranous tubules and sacs involved in protein and lipid synthesis. It is present in both plant and animal cells.

This completes the identification of all labeled parts in the diagram.
