As the image or labels are not provided, lets generally look at structures which are common to all cells (eukaryoic)

Explanation:

The eukaryotic cells can be divided into two main types: plant cell and animal cell.

The similar structures in both of these cells include:

Cell membrane: The covering which is semi- permeable and protects the cell from the external environment.

Cytoplasm: The fluid in which all the organelles of a cell float.

Vacuole: Storage house of a cell.

Nucleus: The are where all the hereditary material exists.

Ribosomes: Organelle where proteins are made.

Endoplasmic Reticulum: Also associated with the making of proteins.

Golgi-complex: Area where proteins are modified and packaged.
