What are the similarities between plant and animal cells?

Both plant and animal cells share several fundamental characteristics that reflect their commonality as eukaryotic cells. One of the key similarities is the presence of mitochondria and ribosomes. Mitochondria are crucial for energy production through cellular respiration, while ribosomes are essential for protein synthesis. This means that both cell types have the necessary machinery to generate energy and produce proteins, which are vital for their growth, repair, and overall functioning.

In contrast, the other options present statements that do not hold true across both types of cells. For instance, while it is true that plant cells possess cell walls, animal cells do not; hence, the distinction doesn't apply here. Additionally, while plant cells typically can be larger than animal cells, this is not a universal rule, as size can vary widely among different cell types. Finally, claiming that animal cells lack organelles is inaccurate, as animal cells are equipped with various organelles that perform specialized functions, similar to those in plant cells.
