What is a similarity between all bacteria and plants? a. they both have a nucleus b. they are both composed of cells c. they both have chloroplasts d. they both lack a cell wall?

The correct answer is b.they are both composed of cells

Explanation:

Both bacteria and plants are composed of cells. Bacteria is a single cellular organism so it is composed of only one cell while plants are multicellular organism, therefore, it is composed of many cells.

Bacteria are prokaryotes so bacterial cells do not contain a membrane-bound nucleus and other membrane bound organelle but plants are eukaryotes so they have a membrane-bound nucleus and other membrane-bound organelle.

Both bacteria and plant cells have cell wall outside their cell membrane. Plant cell wall is made up of cellulose which bacterial cell wall is made up of peptidoglycan of lipopolysaccharide.
