Plants and bacteria both have cell walls but they are shaped differently. Unlike bacteria cells, plant cells and animal cells both have membrane bound organelles such as a nucleus, ribosomes, lysosomes, Golgi apparatus, endoplasmic reticulum, the cytoskeleton, microvilli, smooth endoplasmic reticulum and cell membranes.
However, plants also have food vacuoles and chlorophylls which most animal cells don't have. Furthermore, plant and animal cells are both eukaryotic cells and bacteria cells are prokaryotes. Bacteria cells lack membrane bound organelles, don't have mitochondria and have a nucleoid where the genetic information is stored instead of a nucleus.
Also, bacteria multiply by binary fission instead of mitosis and meiosis which are both used by eukaryotic cells. Bacteria use their cell membrane to produce ATP instead because they lack mitochondria.
