Final answer:
The cell structures found in both animal and plant cells are the a) cell membrane, Golgi apparatus, and nucleolus, with each playing vital roles in cell function and maintenance.
Step-by-step explanation:
The cell structure that are found in both animal and plant cells are A) Cell membrane, Golgi apparatus, Nucleolus. These structures play crucial roles in cellular function and are essential components of eukaryotic cells.
- The cell membrane forms the boundary of the cell, controlling the movement of substances in and out of the cell.
- The Golgi apparatus modifies, sorts, and packages proteins for secretion or for use within the cell.
- The Nucleolus is a region within the nucleus where ribosomal RNA is produced and ribosome assembly begins.
Other structures such as chloroplasts, the cell wall, and a large central vacuole are unique to plant cells, while animal cells may contain lysosomes and centrioles that are not found in plant cells.
