Identify a structure other than a cell wall or a vacuole that might be found in a plant cell but not in an animal cell. explain why

One structure that can be found is most plant cells is chloroplast. A plant cell may have around 0 to 20 chloroplast, depending on their location in plant or their function.

Chloroplast is the structure that photosynthesis occurs. Photosynthesis is the method that plant make food for themselves. They turn sunlight into food such as starch.

Plants are autotrophs, which means they make food themselves, they don't need food from other sources like animals. Therefore, chloroplast is not found in animal cells because we are heterotrophs, we feed on other food.

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein
